Electrical Motor Shaft Power - Engineering ToolBox

Power is in general rated in watt (W) or horsepower (hp).The old imperial unit horsepower is equal to 746 watts (0.745 kW) or 33000 lb ft per minute (or 550 lb ft per second).. The unit of electric power - 1 watt - is equal to the power produced by an electrical current of 1 amp at a potential difference of 1 volt. 1 watt = 1 / 746 hp; 1 hp = 746 watts = 0.76 kW
