You need a Megger tester. With one lead attached to the winding and the other attached to the motor housing, the Megger sends a high voltage through the winding. The Megger reads the resistance, letting you know if there is a short to ground.
Ideally megger test is the best test used to check the resistance of motor winding.
Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.
Ohmmeter
The resistance of a motor winding is expressed in
a start winding on a motor is used to add torque to start a motor, and more importantly to establish the direction that the motor will turn. to reverse a motor normally means to reverse the start winding. the run winding will work the same in either direction, the start winding determines the direction.
when the field winding of a running dc shunt motor suddenly breaks open the motor fails to run because in the motor the stationary winding is armature and rotatory is field winding
In D.C Shunt motor, the field winding is connected parallel with the armature winding.. If you remove the supply to armature winding, the motor will stop after some time.
because its winding follows the wave sign
Bad switch? stalk bad wiper motor? bad low speed winding
The run winding of a single phase capacitor start motor has a lower resistance than the start winding.
Check to see if you are getting power and ground to motor - if so and motor does not work- bad motor
A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.
