摘要: In many industrial and domestic applications an electric motor is required to operate in the so-called constant power region. Constant power, when referred electrical motor, characterised by a mechanical output of at any rated torque speed. The product its speed. For operation, this means that low speed, high generated speed produced. Electrical Vehicles (EV), washing machines most appliances, milling operation selecting cost maintenance variable direct drive system for applications, three systems can be considered. These are Induction Motor (IM) drive, Switched Reluctance (SRM) Permanent Magnet Brushless (PMBM) drive.
