How to measure the quality of fan motors with digital multimeter?
The DC resistance between the 3 wires is measured respectively by the multimeter. The maximum value is the resistance value of the starting winding and the running winding, followed by the resistance value of the starting winding and the resistance value of the running winding.
In the multimeter stalls placed in the 20M file, measuring winding (using the motor three lines in any one) and the motor stator core insulation resistance, the resistance should be above 2M, can determine the motor only problem
The data is related to the material of the line and the power of the motor. And your motor is endless.
The digital multimeter stalls on 2K ohm ohm, single-phase AC fan motor is 220V, starting with starting capacitor, motor has two windings, a starting winding, a winding is running; the starting winding resistance, running small winding resistance.
