    What do you need to know to calculate Motor Efficiency?

    This tool provides you with motor efficiency determination through a calculation of electrical power input versus useful mechanical power output. The ability of a motor to convert electrical energy into mechanical energy effectively serves as an essential factor for performance evaluation. The expression the calculator utilizes follows this format:

    You need to enter the wattage input power together with the watts of output power to use the calculator. The efficiency percentage provided by the calculator lets you evaluate the operational condition of your motor. Motor efficiency reflects operating performance, so a high reading indicates proper function, but a low reading requires investigation of power loss, mechanical wear, and electrical inefficiencies. Engineers, along with technicians, need this tool to observe motor performance while lowering energy use, which eventually optimizes system operational effectiveness whether operating AC or DC motors.

    Conversion using the Motor Efficiency Calculation Formula

    The Motor Efficiency Formula is used to calculate the efficiency of a motor by comparing the output power (mechanical power) to the input power (electrical power). The formula is:

    To find an electric motor's motor efficiency, use the calculator and enter the value of horsepower, load (output power), & input power.

    Efficiency(%) = Output PowerInput Power × 100

      Where:

    • Output Power = is the useful mechanical power delivered by the motor (measured in watts (W)).
    • Input Power = is the electrical power supplied to the motor (measured in watts (W)).
