www.allaboutcircuits.com/textbook/alternating-current/ch…What is the resistance of a sine wave motor?Your resistance should be in the range of 0.1 ~ 50 ohm or so depending on the motor type. 2) Assuming that your power source is a sine wave at 230V, we know that This, assuming that the motor is stalled when you have measured the current. If the motor is allowed to rotate, back emf comes in and this solution is no longer valid.
