1. For new or long-term out-of-service motors, the insulation resistance between the windings and the windings to the ground should be checked before use. Usually for motors below 500V, 500V insulation resistance meter is used; 1000V insulation resistance meter for 500-1000V motors; 2500V insulation resistance meter for motors above 1000V. The insulation resistance shall not be less than 1 MΩ per kilovolt working voltage and shall be measured in the cooling state of the motor.
2. Check whether there are cracks on the surface of the motor, whether the fastening screws and parts are complete, and whether the fixing condition of the motor is good.
3. Check whether the motor transmission mechanism works reliably.
4. According to the data shown on the nameplate, such as voltage, power, frequency, connection, speed, etc., whether it is consistent with the power supply and load.
5. Check whether the ventilation of the motor and the lubrication of the bearing are normal.
6. Pull the motor shaft to check whether the rotor can rotate freely and whether there is any noise when rotating.
7. Check whether the brush assembly of the motor and the brush lifting mechanism are flexible, and whether the position of the brush handle is correct.
8. Check whether the motor grounding device is reliable.

Principle and classification of stepper motor drivers
A stepper motor driver is an actuator that converts electrical impulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to roll a fixed viewpoint (called the "step angle") in the set direction.

Buke human-machine interface - what principles should be considered in the design of human-machine interface?
1. The basic design principle of user-centered
In the design process of the system, the designer should grasp the characteristics of the user and discover the user's needs. In the whole development process of the system, it is necessary to continuously solicit the opinions of users and consult with users. The design decision of the system should be combined with the user's work.

How to accurately control the torque of the Stepco servo motor - synchronous motor?
1. The indicated value is large (or out of range).
According to the investigation of our staff, this kind of problem often appears in the atmospheric pressure workshop. When we find that the counterweight of the float in the float level gauge is at a low point, the liquid level must be very high at this time, and the glass plate is inconsistent with the indication of the instrument.
