A smart motor drive system for domestic and industrial applications
… industrial and domestic applications an electric motor is required to operate in the so-called constant power region. Constant power, when referred to an electrical motor, is characterised by a constant mechanical output power of the motor at any rated torque and speed. The mechanical output power …
