Webb7 juli 2024 · Ohm’s law tells you that current through a wire – even a long wire wound around a motor solenoid – is equal to the voltage divided by the resistance. You can determine the resistance of a motor coil if you know the wire gauge, the radius of the solenoid and the number of windings. What happens if you lose a phase on a 3 phase … WebbTo find the first, second, and third winding resistance, connect the second probe with each winding respectively. A vey high reading, usually in megohms or gigaohms, will indicate a healthy motor insulation. If 0 ohms or overload is detected your motor may went bad. Use 500 V megger for low voltage motors, up to 600V motors.
