工業機器人通常執行重復的動作以完成相同的工序。為保證工業機器人在生產中能夠可靠完成工序任務并確保工藝質量，對工業機器人的定位精度和重復定位精度要求很高。因此提高和確保工業機器人的精度就需要采用rv減速器或諧波減速器。

Industrial robots typically perform repetitive actions to complete the same process. To ensure that industrial robots can reliably complete process tasks and ensure process quality in production, high requirements are placed on the positioning accuracy and repeated positioning accuracy of industrial robots. Therefore, to improve and ensure the accuracy of industrial robots, it is necessary to use RV reducers or harmonic reducers.

精密減速電機在工業機器人中的另一作用是傳遞更大的扭矩。當負載較大時，一味提高伺服電機的功率是很不劃算的，可以在適宜的速度范圍內通過減速器來提高輸出扭矩。而且伺服電機在低頻運轉下容易發熱和出現低頻振動，對于長時間和周期性工作的工業機器人，這都不利于確保其精確可靠地運行。

Another function of precision reduction motors in industrial robots is to transmit greater torque. When the load is large, blindly increasing the power of the servo motor is not cost-effective. You can increase the output torque through a reducer within a suitable speed range. Moreover, servo motors are prone to heating and low-frequency vibration during low-frequency operation, which is not conducive to ensuring accurate and reliable operation of industrial robots that work for long periods of time and periodically.

精密減速電機的存在使伺服電機在一個合適的速度下運轉，并精確地將轉速降到工業機器人各部位需要的速度，提高機械體剛性的同時輸出更大的力矩。與通用減速器相比，機器人關節減速電機要求具有傳動鏈短、體積小、功率大、質量輕和易于控制等特點。

The existence of precision reduction motors enables servo motors to operate at an appropriate speed and accurately reduce the speed to the required speed for various parts of industrial robots, improving the rigidity of the mechanical body while outputting greater torque. Compared with universal reducers, robot joint reduction motors require characteristics such as short transmission chains, small size, high power, light weight, and easy control.
