Installation, Operation and Maintenance ManualSmall DC Motors •56 Frames2Small DC MotorsReceiving and HandlingAcceptance Unpack motor carefully and inspect for possible damage during shipment.Check packing materials and save any instruction tags or wiring diagrams found in the carton. Report any damages or shortages immediately to the local transportation agent.Installation MountingCheck nameplate data on motor before installing to assure the correct rating and that the available power supply agrees with the required motor power supply.Motor should be mounted on a firm foundation.If the foundation is not flat, use shims to prevent misalignment when tightening hold-down bolts. DC motors arc equipped with ball bearings and may be operated in any position.For any position other than base down,new drain holes should be provided so that condensation is allowed to run off. Location should be dry, clean and well ventilated for most satisfactory service. Be sure the possibility of oil seepage into the motor is prevented. Commutator end of the motor should be accessible so that brushes can be conveniently inspected.Mounting Instructions for 56C & 140TC Face Mounted MotorsBefore mounting a “C”face motor to a mating flange,be sure both surfaces and all mounting holes are smooth and free of debris.When mounting into a quill type reducer, make sure the input and output shafts are coated with an anti-seize compound suitable for the application.!ATTENTION:Only qualified electrical personnel familiar with the construction and operation of this equipment and the hazards involved should install,adjust,operate,and/or service this motor.Read and understand this manual in its entirety before proceeding. Failure to observe this precaution could result in personal injury or loss of life.!ATTENTION:High voltage and rotating parts can cause serious or fatal injury. The use of electric machinery, like all other utilization of concentrated power and rotating equipment, can be hazardous. Installation, operation, and maintenance of electric machinery should be performed by qualified personnel.Familiarization with NEMA safety standards, national electrical code and sound local practices is recommended.!ATTENTION:To guard against personal injury or death causedby contact with moving parts, guards (coupling, belt, chain, etc.)must be installed. Machines accessible to the public should be further guarded by screening, guard rails, etc.Small DC Motors 3When mounting through a flexible coupling, verify that there is adequate clearance between the driven equipment shaft, the coupling interface and the motor ck of clearance may result in binding of the shafting and premature bearing failure.Always slide the motor tenon into the mating flange to its full depth before tightening the mounting bolts. Do not allow the motor to hang by the shaft extension while assembling it to the driven equipment (i.e. quill input gear case). This may bend or crease the shaft and damage any seals that are present.Only use the proper mounting bolts. These should be 3/8”-16 threads per inch and sized for length such that engagement into the motor flange does not exceed 9/16”. For example, a gear case with a 3/8” flange thickness requires a bolt that is: 3/8” + 9/16” = 15/16” = Maximum Bolt Length Since 15/16” is not a standard bolt length, a 7/8” bolt or a 1” bolt with a lockwasher can be used.AlignmentShafts should be carefully aligned before tightening any couplings. Inspect couplings and shaft for paint, dirt or burrs. If necessary, remove withsandpaper for proper fit. Pulley or coupling should be carefully fitted. Do not hammer on shaft, pulley or coupling.ApplicationPermanent Magnet “PM”motors are not always designed for across the line starting. This may cause loss of flux resulting in an increase in speed and possibly instability. Wound field motors can be started across the line with full applied voltage. However, for frequent starting or reversing, voltage should be reduced for normal brush and commutator life.Dynamic or regenerative braking methods should not be used unlessprovisions are made to limit the maximum instantaneous current to a value not greater than the maximum allowable peak amperes shown on the nameplate. This also applies to plug reversing the PM motor.ConnectionsAll motors should be installed in accordance with the National Electric Code and local requirements. Fuses, thermal cutouts and other protective devices should be the proper size and rating to safely carry the load and to interrupt the circuit on overloads.!ATTENTION:To guard against motor damage such aspremature failure and/or a loose assembly, use only mountingbolts that are the correct length.A bolt that is too long may cause damage to the motor.4Small DC MotorsConnection diagrams are shown above. Care must be taken to ensure that the dual-voltage shunt field is properly connected.Some DC motors are equipped with a thermostat inside the motor. This thermostat has a normally closed (NC) contact which opens if the motor temperature exceeds design limits due to extended overload operation.Leads from the thermostat are labeled P1& P2and should be connected in series with the drive “STOP” button (refer to the previous figure).!ATTENTION:Ground the machine properly to avoid seriousinjury to personnel. Grounding should be in accordance with theNational Electrical Code and consistent with sound local practices.+A1High Voltage Connection 1, 2Low Voltage Connection 1, 2High VoltageConnection1, 2LowVoltageConnection 1, 2Permanent Magnet Thermostat (if furnished)GroundConnection Connect in Series with Control Stop DeviceEarth Ground Series A2S1+F1F11F2A1+A2S1+F1F11F2+A1A2S1–S2+F1F11F2A1+A2S1+F1F11F2S2F22S2F22F22–S2F22+A1TypeS h u n t S t a b i l i z e d S h u n t a n d C o m p o u n d CCW Rotation Facing Commutator End CW –A2+F1F11–F2+A1A2S1S2A1+A2S1S2F22+A1–A2–A1–A1+A2+F1F11–F2F22+A1A2+F1F11F2F22–A1+A2+F1F11F2F22+A2P1P21Motors with single voltage fields do not have leads F11 & F22. Leads F11 & F22 may be marked F3 & F4, respectively. Connect on low voltage field connection.2Consult motor nameplate to determine value of low and high voltage connection.Small DC Motors5Important:When motors are provided with thermal protection (typicallythermostats), it is important to properly connect and apply thedevices. This will ensure that the motor is properly protectedfrom being operated if thermal limits are reached and/orexceeded.The control system must be configured to reduce themotor load and/or shut down the motor control system to allowthe motor to cool to a level within acceptable operating ranges.If the motor is operated with the thermal protective devicestripped (indicating an over temperature condition), the motorinsulation could be damaged and complete failure of the motorinsulation is possible. In the event of motor failure due to anover temperature condition,Rockwell Automation requires thatmotor thermal protective devices (when supplied) beadequately monitored and incorporated into the motor controlsystem to maintain warranty. Failure on the part of theindividual installing this equipment to take these steps willresult in the factory warranty being voided.OperationThese motors are inherently capable of operating over a wide range ofspeeds and loads. If the motor is not operated on the type of power supplyfor which it was designed, performance will differ from nameplate valuesand applicable standards.The motor should start quickly.If it fails to start,the load may be too great,the applied voltage too low, or the motor improperly connected and/or thecontrol misadjusted (check particularly current (torque) limit adjustment).In any case, immediately disconnect the power and investigate the cause.While operating the motor, observe the performance. Any undue noise,overheating, sparking or erratic performance should be investigated andnecessary corrective action taken to prevent serious damage.Maintenance The fundamental principle of electrical maintenance is keep the apparatusclean and dry.This requires periodic inspection of the motor,the frequencyof inspection depending upon the type of motor and the service.!ATTENTION:Internal parts of this motor may be at line voltage even when motor is not rotating. Disconnect all AC line connections before contacting any internal part.6Small DC MotorsBearingsBall bearings are deep grooved, double shielded with sufficient lubricantpacked into the bearings by the manufacturer for “life lubrication.” Theinitial lubricant is supplemented by a supply packed into larger reservoirs inthe end shield at time of assembly. No grease fittings are provided. Theinitial lubrication is adequate for up to 5 years of operation under normalconditions.Should it become necessary to replace bearings,the bearing bore and cavityshould be thoroughly cleaned and repacked with approximately 1/2teaspoonful of recommended grease.Bearings should be removed with bearing pullers using a center insert in theend of the shaft to protect the shaft center. To reinstall ball bearings, eitherin a press or on the bench, pressure should be applied to the inner race byusing a square faced sleeve or piece of pipe that will fit over the shaft, toavoid damaging the bearing. If a press is not available and a hammer isused,the blows should be transmitted against the sleeve by a block of woodor fiber.BrushesCheck brushes to make certain that they move freely in the holders andmake proper contact with the commutator. Re-place worn brushes. Givecomplete motor identification when ordering parts. New brushes should bepre-radiused to fit the commutator curvature. Blow out the carbon dust.Short brush life and poor commutation may be due to a rough commutator,a shorted armature, or poor undercutting of mica. Dirt and chemicals in theair are common causes of trouble.CommutatorThe commutator should remain a polished surface.Blackening may indicaterough or eccentric commutator. Occasional wiping (power off) with drycanvas or non-linting cloth may suffice. If rough or excessively dirty,smooth with very fine (00) sandpaper lightly with armature rotating. Neveruse emery cloth. Never allow the brushes to wear so short that springtension is lost. The resultant sparking will seriously damage thecommutator.If frequent dressing is required,the cause should be found and corrected.Avery rough commutator should be turned in a lathe, at high speed, with asharp tool.Do not remove more copper than necessary.The mica should beundercut if necessary.An authorized service shop is recommended for this work.Small DC Motors 7General The following should be checked at regular intervals:•Windings should be dry and free of dust, grease, oil, and dirt. Windings may be cleaned by suction cleaners or by wiping. Nozzles on suction type cleaners should be non-metallic.Gummy deposits of dirt and grease may be removed by using a commercially available low volatile solvent.Do not use gasoline or other inflammable solvents.•Terminal connections, assembly screws, bolts and nuts should be tight.They may loosen if motor is not securely bolted and tends to vibrate.•Insulation resistance of motors in service should be checked periodically at approximately the same temperature and humidity conditions to determine possible deterioration of the insulation. When such measurements at regular intervals indicate a wide variation, the cause should be determined. Motor should be reconditioned if the motor has been subjected to excessive moisture, or by rewinding or reinsulating if necessary. Enclosed motors require very little attention. Be sure that external air chamber of fan cooled motors does not become clogged with foreign material which will restrict passage of air.Troubleshooting If trouble develops in operation of motor, verify that:1.The bearings are in normal condition and have been properly lubricated with a high grade,ball bearing lubricant,free of dirt or grit.If dirt enters bearing, flush and relubricate.2.There is no mechanical misadjustment to prevent free rotation of moving parts of motor and drive.3.All bolts and nuts are properly tightened.4.Motor instructions have been carefully carried out.5.The rated voltage is available at the motor terminals.6.The voltage corresponds to the value stamped on the nameplate.7.All connections are properly made in all circuits between motor and control.8.The overload and low voltage devices in control equipment, fuses or other protective devices are in proper working order.9.Brushes are in good condition and are making good con-tact with the commutator.10.The commutator is clean and has smooth polished surface.11.No excessive overload exists on the pare line amperes at full load with nameplate stamping.!ATTENTION:Internal parts of this motor may be at line voltage even when motor is not rotating. Disconnect all AC line connections before contacting any internal part.Online DocumentationThe latest motor information can be obtained from the Allen-BradleyDrives & Motors home page on the World Wide Web at:Publication1325R-UM001B-EN-P Ð A ugust, 2001Supersedes 1325R-UM001A-EN-P dated May, 2001Copyright © 2001 Rockwell Automation.

这些膜片组由一个或多个中间接筒隔成多个膜片组。
膜片组能承受的轴向和角度方向的变形量和不对中量有极限值限制。
这些极限值是对这种联轴器所规定的。
要十分小心，别超过这些极限值。
单个膜片常常有多边形外形，这些构成特定厚度的膜片组的膜片通过衬套来固定。
在螺栓孔中心处，螺栓穿过衬套孔，衬套穿过膜片组的孔来连接驱动机端和被驱动机端半联轴节，并传输扭矩和挠性。
螺栓、衬套和相应的孔应按较小的公差制造。
然而，由于实际组装的需要，衬套和螺栓与孔的配合应是间隙配合。
为了补偿这个间隙，和保证与膜片组相邻的零件保持同心，应使法兰螺栓孔中心直径比膜片组螺栓孔中心直径稍大。
这样膜片组在组装后就稍微“拉紧”。
组件上的螺栓上紧到相对紧的程度，以产生巨大的预紧载荷。
这一预紧载荷对于避免在工作的情况下螺纹旋合面发生的滑丝，或对于消除由于传输扭矩产生的外伸力拒所导致的螺栓弯曲等有着重要的作用。
这样上紧螺栓被认为是相当重要的。
通常这种设计原理在许多已投用的装置上都得到了证实。
2. 操作条件和极限在工作的情况下，膜片组承受由于扭矩，转速和不对中所造成的巨大拉伸和弯曲应力。
这些应力都与其中一种应力影响另一种应力的许用极限的程度大小的变化相关联。
在正常情况下，扭矩随转速而变化。
这种变化关系的重点在于不对中的程度。
正因为如此，轴向挠曲的程度的变化将改变角度不对中的允许程度。
因此，在所有的操作条件下，联轴节上的不对中量应维持在最终设计数据所陈述的最大允许值以内，这一点非常重要。
初始不对中量应尽可能精确，并应维持在本文的对中和\或安装说明章节上给定的对中极限值以内。
在机器操作期间，允许（正常或事故状态下的）更大位移时的初始极限值应尽可能的低。

HMDS磁选机安装调试,运行和维护保养手册
HMDS－９１４×２９７２磁选机安装调试，运行和维护保养手册（合资）抚顺隆基磁电设备有限公司目录１．注意事项２．工作原理及特点３．润滑４．安装、调试及运行５．操作、维护与安全６．易损件表一、注意事项为确保您的人身、设备及财产的安全，在使用设备之前，请您务必阅读使用说明，并在以后的搬运、安装、运行、调试与检修过程中遵照执行。
1、安全注意事项（1）使用前请仔细阅读说明书并请遵照其注意事项。
（2）佩带起搏器或类似医用电子设施的人群禁止靠近磁选机。
2、使用注意事项；（1）检查清除所有料箱中的杂物，尤其是滚筒和料箱之间。
铁质物件一旦进入槽体和滚筒之间，清除的难度很大，因此安装调试直到正常运行期间，一定要采取措施防止杂物落入。
（2）每三个月左右定期加注润滑油。
（3）每一个班次停止工作后清理进料箱、槽体以及排粗机构中的杂物。
二、工作原理及特点1、概述HMDS型磁选机适用于矿山、选煤厂等单位，用于弱磁场湿式选别细颗粒的强磁性矿物，或者除去非磁性矿物中混杂的强磁性矿物。
如回收重介质选矿中的磁性重介质加重剂，铁选矿厂中低浓度矿浆的浓缩和磁铁矿物的富集，处理强磁选机的给矿，清除其中的磁性或较弱磁性矿物及其连生体，防止磁介质堵塞。
HMDS型磁选机采用计算机优化设计，磁路合理并严格选用高矫顽力，高剩磁的永磁体，确保磁性在长时间内不降低，所以处理矿浆体积量大，磁性铁回收率高，再选后的尾矿一般再无回收价值。
选到精矿中非磁性矿物夹杂少，精矿品位可调整，矿浆浓缩或不浓缩皆可入选。
使用中操作简单，管理方便。
保障用户的长远利益，整体结构可靠耐用。
2、工作原理逆流槽型磁选机适用于粒度0.6~0毫米强磁性矿物的湿式粗选和扫选，可获得粗精矿和尾矿两种产品。
矿浆由给矿箱均匀地给入槽体，在分选空间入口处，有特殊的弧形凸起，以使不同矿粒能在分选空间中沿整个给矿宽度上均匀分布，充分悬浮，使流动方向与磁力方向一致，有利于圆筒充分吸引磁性物．磁性较强的矿物受磁力作用，被吸附于圆筒表面，随圆筒旋转带磁性区，在重力和旋转抛力下流入精矿槽，非磁性物由溢流口排出，溢流堰具有一定高度保证圆筒在矿浆中在一定的浸入深度，这是由结构而定，不需象顺流槽那样人为控制溢流。
