AboutCharles C. Jones Expertise Let Me help you with your problems with single phase and three phase electric motors. I can tell you how to troubleshoot your motor problems. From simple testing of capacitors, how to test your windings, replacing bearings, and general maintance. Before we go any further, remember these words of advice: Disconnect the power before you do anything! Please limit your questions to electric motors and there immediate components. I review each question, and if I can answer or help, then I will. If you receive a rejection, it means it is out of my expertise, and just do not have the answer. I'll be waiting for your question, and see if I can help you. Thanks for using AllExperts!
Experience I have 30 years experience in the repair of electric motors and related equipment. I am a master machinist in the field of motor repair. I have been employed with my company for 27 years. When you ask your question, give me all the information you can about your problem. I have a lots more to add, but for the everyday do-it yourself kinda person, it might get to technical. So ask away, if I can't give you a good answer, I'll find someone who can
Expert: Charles C. Jones Date: 7/12/2008 Subject: ohm out a motor with meter set on ohms.
Question WHEN I WANT TO OHM OUT A MOTOR TO SEE IF IT'S GOOD OR NOT. COULD YOU TELL ME HOW TO GO ABOUT IT AND WHAT MY METER WILL READ IF I OHM IT OUT.
Answer An ohmmeter is not a very good test for a motor. It will show you continuity in the circuit. It can show you a possible problem in three phase circuits, as the ohms will be different phase to phase in a shorted motor.
In single phase, removing the leads from a capacitor and connecting them to the ohmmeter can show a dead spot in the start winding, as well as a open circuit. An exact reading is impossible to give, due to the varying resistance in a individual motor, but should be close to "0".
