A cloth moistened with mild detergent solution shall be used to wipe the surface, and then it shall be wiped with a dry cloth.4.7 Maintenance and repair of bearing4.7.1 Maintenance and repair of rolling bearingRolling bearing is the standard replaceable part.The grease grade used for rolling bearing shall comply with the standard requirements. The grease has a finite life, and under the influence of mechanical stress and chemical aging, it has gradually lost its lubricating properties. Therefore, it needs to be regularly replaced.For the allowable temperature of rolling bearing, see 4.1.2, so that the grease can achieve the expected normal life.4.7.2Replacement of lubricantGenerally, 50g lubricant shall be injected once a month, and complete replacement shall be conducted once a year. However, this depends largely on the running time, operating temperature and the degree of oil contamination. In case of severe turbidity or sudden rise in temperature without external influence, the lubricant shall be replaced.4.8Maintenance and repair of slip ring ring and carbon brush4.8.1 The surface of slip ring shall be kept smooth and cylindrical. After a period of running, slip ring contact surface will form a layer of oxide film containing graphite, and the surface film may be in color between light gray and black, depending on carbon brush grades, current density, air temperature and humidity.When the surface of slip ring is not smooth, but is covered with rust and burn marks, the fine sand paper can be used for grinding.4.8.2To make two rings be worn uniformly, their polarities need to be replaced once to twice within one year.4.8.3 During the running of motor, it is normal that the carbon brush wear is less than 6mm/1000 hours. When the carbon brush is worn too much, you should also get a new carbon brush. The grade of the new carbon brush must be the same as that of the original carbon brush. The contact surface between the new carbon brush and the slip ring shall be machined into the arc that is the same as the radius of slip ring, in order to ensure the good contact between the carbon brush and the slip ring.4.8.4On the insulation between the slip ring and the carbon brush holder, the extent of accumulation of dust shall be regularly checked and the dust shall be cleared away, preferably by removing the toner with a vacuum cleaner, and blowing with compressed air, and finally wiping with a clean dry cloth.4.9 Routine inspection of motor during running4.9.1 Measure the stator (armature) winding temperature, bearing temperature, inlet and outlet airtemperature, analyze the records, and inspect that there is abnormal situation.4.9.2 Inspect that the motor has unusual mechanical noise or the changing sound (such as friction or percussion sound, etc.).4.9.3Vibration measurement, the measuring point can be selected in the middle of the bearing chamber.4.9.4Inspection of lubrication system, including the oil level of bearing, the rotation state and oil-bring extent of slip ring, any oil spills and discoloring of lubricant, etc.4.10 Regular shutdown maintenance period of motorThe regular shutdown maintenance period of motor shall be based on site conditions and type of the motor structure, typically be in accordance with the following deadlines:a.Motor overhaul: once a year;b.Motor repair: 2-4 times per year.5 Motor failure analysis5.1 Possible failure of synchronous motor5.1.1 During start-up, due to the too low supply voltage, the motor can not rotate.The decrease rate of the motor start-up torque is proportional to the square of the voltage drop. If the decreased start-up torque is less than the load resistance torque, the motor will not rotate.5.1.2During start-up, the motor has magnetic noise, but the rotor does not rotate, with obviousvibration.This may be because the motor is started after being supplied with the excitation current. Now, the excitation status of the excitation device shall be inspected.5.1.3 During start-up, the motor gives normal magnetic noise, but the rotor does not rotate.This may be because the load torque is too large, or the increase in load is more than the motor start-up torque due to a failure of dragged machine.5.1.4 During start-up, the junction of damping ring sparks.Usually, the connecting bolts are not tightened, or the junction of damping ring has bad contact.5.1.5 The motor fails to be frequently started in accordance with the requirements of Section 3.4.3, so overheating is caused to the start-up winding, resulting in unsoldering or breaking of damping bar.5.1.6 During start-up, due to the low supply voltage and insufficient torque, the speed can not be increased to 95-97% of rated speed, resulting in non-pull-in synchronization.5.1.7 The setting range of excitation part of excitation device can also cause non-pull-in synchronization.5.1.8 Slip ring flash or singeing, mainly due to:5.1.9 The cylindrical coaxiality of slip ring is not good, or the surface of slip ring is rough.5.1.10 The grade of the carbon brush is inappropriate, or the pressure on the carbon brush is too small, which hinders the carbon brush from sliding because of being tightly packed in the carbon brush box.。

同步电机技术参数
MQY5580溢流型球磨机同步电机技术参数3.3磨机设备外配套件部分技术说明——主电机MQY5580溢流型球磨机配置为磨机专用的TDMK 型低转速有刷励磁同步电机，Y 接星点打开并引出，留有配置液态软启动装置的接口，主电机空负荷起动。
允许电压的偏差范围为±5%，因为功率因数超前，对电网有一定的补偿作用。
电机技术数据：此时电动机的起动电流与端电压成正比下降，而起动转矩则与端电压成正比降低。
主电机通过空气离合器与小齿轮联接，实现单级减速传动，驱动回转部转动。
因为装备了空气离合器，可以实现电机——磨机分段起动，首先起动主电机，当主电机达到额定转速时，向空气离合器的气囊中充气，4～6秒内空气离合器的气囊达到额定压力压着闸瓦抱紧轮毂，带动小齿轮，驱动回转部回转。
分段起动可降低起动电流，改善起动条件，减少了对电网的冲击，空气离合器可使电机的起动力矩仅为额定力矩的0.4倍（一般要达到1.8～2.8倍）,牵入转矩为额定力矩的0.3倍（一般为1.0倍），起动电流为额定电流的3倍左右（一般为6～7倍）。
这样电机可获得良好的机械特性，尚可避免对电源造成巨大的冲击，可相应减小选矿厂主变压器的容量，降低无功损耗，同时可以降低磨机的装机功率。
主电机进入PLC信号有定子温度、轴承温度、轴承振动、电机电流。
