test electric motor
(OP)
there is any way i can check or test a 110v , ac electric motor with a simple multimeter tester, this is my swiming pool pump motor, is completly dead it has current(i don't want to start removing all the filtering system without checking the motor first)
RE: test electric motor
First, try finding the ground resistence of the motor. Put the multi-meter in kilo-ohms and check the resistence between the motor body(or your metallic connector box) and the terminals of the motor. It should show a fairly high value- could be 100 K-ohms or above. Else, there is a ground leakage- this is probably the reason why you get shock.
Next, you could find the resistance of the winding. Connect between the terminals. (I don't know the type of motor used). Across the motor windings you should get a low finite value- could be a couple of hundred ohms.
