It is also important to make sure that there are no short circuits in the winding, as this will also result in an incorrect calculation. This can sometimes be tricky as each manufacturer may use different types for their motors. The most important thing in calculating Motor Winding Resistance is determining what type of windings are in use. How to Calculate Motor Winding Resistance? To achieve this, it is necessary to know details about the power losses in the machine, including voltage drop in cables and current loss in windings, and other factors that affect performance and efficiency, such as ambient temperature and air circulation within the motor enclosure. An adequately designed motor should have an appropriate input voltage range, frequency, and whole-load currents for reliable operation over its service life. Lower winding resistance results in higher efficiency and better performance in general terms.

This will result in your machine operating at its maximum torque output of 5 HP, with only half of the required horsepower being used. The higher the winding resistance, the less current will flow through the windings and thus cause less torque to be produced.įor example, if you are driving a machine that requires a maximum of 5 HP but has 8 HP motors available, you can use a 4-HP motor as long as it has a lower winding resistance than the other 8-HP motors. The motor winding resistance is the resistance inherent in the windings of an electrical machine. To calculate a motor winding resistance, divide the motor voltage by the motor current. Where R is the motor winding resistance (ohms).
