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...

When the brushless DC motor is used, it may be heated up. If its temperature is too high, it will easily cause damage. BelowFind out how it is tested.1. Measurement of working temperatureThe measurement of the temperature rise of the measured motor is usually carried out at the same time as the bearing capacity and transmission efficiency of the deceleration motor, and can also be carried out separately. The working temperature of the speed reducer under the rated speed and the rated input power is read when the speed reducer is in accordance with the regulations.2. Determination of the temper...
