What are the special requirements for electric vehicle motors in terms of load requirements, technical performance and working environment:1. The electric vehicle drive motor needs 4-5 times overload to meet the requirements of short-term acceleration or climbing; industrial motors only require 2 times overload.2. The maximum speed of electric vehicles is required to reach 4-5 times of the basic speed when cruising on the road, while industrial motors only need to reach constant power, which is twice the basic speed.3, electric vehicle drive motor needs to be designed according to the driving ...

The stepper motor is a special motor used for control. Its rotation is operated step by step at a fixed angle (called "step angle"), which is characterized by no accumulation error (accuracy of 100%). Therefore, it is widely used in various open loop control. The operation of the stepping motor is driven by an electronic device. This device is a stepping motor driver. It converts the pulse signal from the control system into the angular displacement of the stepping motor, or: every pulse signal sent by the control system. The stepper motor is rotated by one step angle by the driver. ...

Stepper motor coupling for mounting between stepper motors and loads requires precise transmission performance:1. Zero clearance: The coupling is not allowed to have clearance during the transmission process, including forward clearance and return clearance;2, high rigidity: that is, the hysteresis of the transmission is not allowed, otherwise it will seriously affect the accuracy of the stepper motor transmission;3, low inertia: on the basis of ensuring the transmission strength, the weight of the stepper motor coupling should be reduced as much as possible;4. Flexibility: The precision servo...
