Electric Motors

Electrical motor efficiency is the ratio between shaft output power and electrical input power.. Electrical Motor Efficiency when Shaft Output is measured in Watt. If power output is measured in Watt (W) then efficiency can be expressed as. η m = P out / P in (1). where. η m = motor efficiency. P out = shaft power out (Watt, W). P in = electric power in to the motor (Watt, W)

Generator Frequency Conversions: 60 Hz and 50 Hz Used ...

As per the above formula, a 2pole generator producing an output frequency of 60 Hz has an engine speed of 3,600 rpm. To change the output frequency to 50 Hz for the same generator configuration, the engine speed needs to be reduced to 3,000 rpm. Similarly, for a 4pole generator, an engine speed of 1,800 rpm produces output of 60 Hz.
