# Motor Winding Resistance Calculator | Key for Efficient Motors

In the realm of electrical engineering, various tools, and formulas are utilized to assess and ensure the efficiency of electric motors. One such vital tool is the Motor Winding Resistance Calculator.

## Definition

The Motor Winding Resistance Calculator is a mathematical tool used to determine the resistance present in the winding of an electric motor. This calculation helps in assessing the motor’s efficiency and performance, and any potential issues.

## Detailed Explanation of the Calculator’s Working

The calculator operates based on Ohm’s Law, which asserts that the resistance (R) equals voltage (V) divided by current (I). By inputting the voltage and current values, the calculator can accurately compute the motor winding resistance, thus providing valuable insights into the motor’s functionality.

## The Formula and Variables

The Motor Winding Resistance is calculated using the formula:

R=V/I, where:

• R denotes the Motor Winding Resistance measured in ohms (Ω).
• V signifies the Voltage applied across the motor windings, measured in volts (V).
• I refer to the Current passing through the motor windings, measured in amperes (A).

## Example Calculation

Consider a motor with a voltage of 220 volts and a current of 12 amps. Using the above formula.

R = 220V / 12A = 18.333 Ω

This indicates that the resistance of the motor winding is approximately 18.33 ohms.
