1. Shake the meter, 500V can shake the meter, and shake the insulation resistance of the line on the three binding posts to the motor shell, which should be above 0.5M ohm, which means that there is no short circuit to the ground (Yantai motor maintenance).
2. Multimeter measurement: measure the resistance value between the three phases of A/B/C, whether it is equal, it should be about the same, and the difference is too much, but it will not take long, remember that the larger the motor, the smaller the resistance! But you can't all three phases be 0 ohms, unless you are particularly large, such as a motor above 50KW! Remember, if it is a speed regulating motor, the resistance value of the 6 terminals is not the same!
3. Check the bearings and fans, and generally wrap the motor to let them all be replaced! Because sometimes the bearing will burn the motor!
4. The no-load current of the motor is generally 10%-50% of the rated current, and sometimes the idling current of the motor is still zero!
5. When the rated current of the motor is running, it is running at full load, and the output power is basically 100%. The running current is small, which means that the output power of the motor becomes smaller, and it is a light load operation.

Buke human-machine interface - anti-interference countermeasures of PLC controller and human-machine interface
1. Adopt a power supply with excellent performance to suppress the interference introduced by the power grid.
For the power supply supplied by the PLC controller, the non-power line power supply should be adopted, and the special line power supply should be used directly from the main bus of the low-voltage distribution room. Isolation transformers are selected, and the transformer capacity should be larger than the actual needs.
