Even when an engine is used, it is useful to convert thermal power into electrical energy by using a generator. Mostly, a single-speed electric motor is used. Although the speed (R.P.M.) of a motor decreases marginally under load, it is considered constant. The maximum torque available, depends upon the motor power-rating (kW/H.P.), and rotary speed [R.P.M.]. Costly two-speed motors can be used conve…
