Motor failure, mainly mechanical failure and electrical failure two. If we want to judge the quality of the coil of the three-phase asynchronous motor, brake motor, torque motor and other products, we can use a multimeter and megohm meter to measure. Here is a simple understanding with Senli Motor Xiaobian.

       To check the quality of the motor, we can use a multimeter and a swing meter to judge:

Use a multimeter to measure:A,B,CThe resistance values of the three phases are equal, and the larger the motor, the smaller the resistance value!But not all three0European, unless it is a particularly large motor;

       To use the dial:500VThe insulation resistance value of the line on the three terminals to the motor housing should be in0.5MThat means there is no short circuit to the ground.

       Brake motor manufacturersReminder: Check bearings, fans, generally wrap the motor will be all replaced, sometimes the bearing will burn the motor; The no-load current is generally rated current10%～50%Sometimes the no-load current of the motor is still zero. When running under rated current conditions, it is running at full load, and the output power is basically100%. The running current is small, indicating that the output power of the motor is small, and it is light load operation.
