Motor Sizing Principles 1. General Concepts Motor : Converts electrical energy into mechanical energy. In this course we will be considering motors which rotate (spin) Mechanical Power: The mechanical output of the motor (P) measured in Watts. Older motors and USA motors measure power in Horse Power (Hp). Conversion Factor: 1 Hp = 746 W

For an electrically driven motor, the output power is mechanical while the input power is electrical, so the efficiency equation becomes efficiency = mechanical power/electrical input power. Part 2: Selecting Instruments for Electric Motor Power Measurement and Analysis
