Measuring Power Consumption in Electric Motors: Methods and

Electrical power input is the energy a motor gets from outside. You find it by multiplying voltage (V) by current (I). This gives the motor''s electrical power input: Input Power (W) = Voltage (V) x Current (I) In India, the usual AC voltage is about 230V. So, this input power shows the electric energy a motor uses over time.
