Although the cause of degradation of insulation has not been clarified, it has been found that the failure rate varies greatly between static uses (DC voltage application) and dynamic uses (pulse voltage application). Like other electrical components, piezoelectric actuators can be affected by humidity as well as applied voltage and ambient temperature. KEMET has added the metal sealed piezoelectric actuators featuring high reliability by eliminating the effects of the ambient atmosphere.This section describes reliability guidelines for static and dynamic usage of the resin coated type actuators. Reliability of our multilayer piezoelectric actuators is represented by MTTF (mean time to failure) in case of static usage.DC Voltage ApplicationThe acceleration factors have been obtained empirically for each of the drive voltage, ambient temperature and relative humidity based on many experimental results. The MTTFr in actual applications is estimated using equation (1) below with MTTFs observed under accelerated conditions as the reference value. (1) MTTFr = MTTFs × A v × A h × A t MTTFr : Estimated valueMTTFs : Reference value (= 500 hours)A v : Acceleration factor for drive voltage = (150/V R )3.2 V R : Actual voltage (V)A h : Acceleration factor for relative humidity = (90/H R )4.9H R : Actual relative humidity (RH%)A t : Acceleration factor for ambient temperature = 1.5(40 -Tr)/10T R Actual ambient temperature (ºC) The following calculation is made for the case of use at 25°C, 60% RH and 100 V.MTTFr = 500 X (150/100)3.2 X (90/60)4.9 X 1.5(40-25)/10 = 500 X 3.66 X 7.29 X 1.84 ≈ 24,500 hours (2.8 years)Pulse Voltage ApplicationIn driving dynamic applications, temperature rises as a result of self-heating allowing the component not to be affected by the humidity, thus extending the operational lifetime. This phenomenon is explained as a result of the humidity factor elimination caused by the self-heating.Since the self-heating value is affected by multiple factors such as the element’s shape, pulse waveform and frequency, it is difficult to estimate the actual rising value. Therefore, the life of the actuator cannot be determined by using an equation, unlike the case of DC voltage applications.When testing the AE0203D08DF part, there was no failure confirmed after 500 hours end of the pulse driving test. (500 Hz, 0 – 150 V rectangular pulse).Users should be careful about the influence of physical damage which can be caused by the fixing method of the element and/or the driving conditions.User’s GuideFixing Method• Carefully prevent the piezoelectric actuators from being bent, twisted or applied tensile force.• Install the actuator so that the center axis of the generated displacement is aligned with the center axis of the load.• Epoxy-based adhesives are recommended for bonding. Select adhesives that have high rigidity and allow for medium thickness so that the generation force and displacement cannot be deteriorated. Also, do not form adhesives on the side of the actuator.• When thermosetting resin is used, perform polarizing treatment (see caution section) after the adhesive is settled.• The resin coated type is weak to the tensile force due to its structure and may be broken when tensile forces are applied onto the device. Using the device in the state that constantly applies compression is effective against any mechanical damage. The pressure applied to this element should be kept at 20% to 50% of the force generated by this element (compression resistance).• Install the element so that the axis of generated displacement is vertical to the mounting surface.Example of Actuator mounting：The actuator may break.a) Example of wrong mountingImperfect alignment between actuator and load<Actuator will be broken>b) Example of correct mountingMount the device so that the load is uniformlyapplied by the spherical surface or the hingeDriving Method• Connect the red lead wire to the positive (+) terminal of the power supply. Also prevent reverse voltage application.• In driving applications, it is necessary to take consideration of hysteresis, ringing, creep, and other similar phenomenons. For pulse driving, it is also necessary to be aware of self-heat generation, charge/discharge current, and the power supply’s impedance.User’s Guide cont’dGenerated force and load relationGenerated force and load relation:Static load: No load value change when actuator moves.Fluctuating load: Load value changes by spring reaction when actuator moves.－10－505101520D i s p l a c e m e n t （μm ）－－－－D i s p l a c e m e n t （μm ）Load （Ｎ）D i s p l a c e m e n t （μm ）D i s p l a c e m e n t （μm ）Precautions• Connect the red lead wire to the positive (+) terminal of the power supply.• Avoid electric shocks since a high voltage is in use.• Never apply excessive tension to a lead wire.• Do not handle the product by picking up or moving the lead wire.• Machining of the actuator element and replacement of the lead wire are prohibited.• Do not handle the resin coated type (AE series) with bare hands.• Do not wash the resin coated type (AE series) with organic solvents.• Avoid excessive physical shock. Otherwise, the internal piezoelectric ceramicelement may be damaged.•If the actuator is exposed to high temperatures above 100°C or if used after long storage periods (more than three months), the device should be polarized by using the circuit configuration and conditions shown at right.• Do not apply voltage exceeding maximum rating voltage, or rapid charging and discharging.• Do not use the actuator in high concentrations of highly inflammable gas.• Align the center axis of displacement of the actuator with the center axis of the mechanical load.• When operated, the transient response time of the actuator should be less than 1/3 of the resonant frequency in order to prevent damage by ringing.• Store the resin coated type (AE series) preferably in a dry atmosphere (desirably below 40% RH) at ordinary temperatures (-5˚C to +40˚C). Avoid condensation on the product’s surface.• Store actuators where there is no vibration.•Handle products properly as industrial waste.

电动执行器工作原理
电动执行器工作原理电动执行器是一种用于实现运动控制的装置，通过电力驱动来完成机械装置、系统或过程中的线性或旋转运动。
它广泛应用于工业自动化、智能家居、航空航天等领域，具有灵活高效、精确可靠的特点。
本文将介绍电动执行器的工作原理。
一、电动执行器的基本组成结构电动执行器由电动机、减速器、传感器、驱动器和控制器等核心组件构成。
1. 电动机：电动执行器的动力来源，常用的电动机包括直流电动机和交流电机。
通过接收来自驱动器的电能输入，电动机可以驱动执行部件进行运动。
2. 减速器：电动执行器通常需要经过减速装置来提供更大的输出扭矩和较低的运动速度。
减速器可以通过齿轮传动、蜗轮蜗杆传动等方式实现。
3. 传感器：传感器用于感知和测量执行器的位置、速度、力量或其它相关参数。
这些信息将被传送到控制器，以便对电动执行器进行精确的控制和监测。
4. 驱动器：驱动器是电动执行器的控制单元，通过向电动机提供合适的电流和电压来控制其速度和方向。
驱动器可以根据控制器发送的信号，实现对电动执行器的精确控制。
5. 控制器：控制器是电动执行器系统的大脑，负责接收用户的指令并将其转化为操作信号，从而驱动电动执行器工作。
控制器还可以接收传感器的反馈信息，实现对电动执行器运动状态的实时监测和调整。
二、电动执行器的工作原理电动执行器的工作原理可以概括为以下几个步骤：1. 接收指令：控制器接收到用户的指令，根据指令确定电动执行器的运动要求，例如位置、速度和运动轨迹等。
2. 电能输入：驱动器向电动机提供适当的电源，根据控制信号提供合适的电压和电流，以满足执行器的运动需求。
3. 动力转换：电动机接收到电源输入后，将电能转化为机械能。
对于直流电机，电能通过电刷和换向器产生的磁场来驱动转子旋转；对于交流电机，电能通过磁场相互作用来产生旋转力。
4. 运动传递：电动机通过减速器将旋转运动转化为直线或转动运动。
减速器根据需要提供适当的输出力、速度和运动范围。
5. 运动控制：传感器监测和测量执行器的位置、速度和力量等参数，将这些信息反馈给控制器。
