The permanent magnet synchronous motor for water pump is a special series of PM motor designed by HIEST according to the operating characteristics of water pump. It can be used for ordinary water pump, submersible water pump and other asynchronous motor operating conditions.
The NdFeB permanent magnet material is embedded inside the rotor of the motor to provide excitation, and there is no induction current in the rotor during operation. It has significant features such as high efficiency, small size, light weight, fast dynamic response, low temperature rise, and wider economic operation range than asynchronous motors.
The permanent magnet motor consists of stator, rotor, bearing device, end cover, junction box, fan/fan cover, in which, the stator is a fixed part of motor and consists of one stator core, base and 3-phase field winding. The rotor, as the revolving part of motor, is mounted with permanent magnet poles. Hiest provides customers with a series of standard and customized permanent magnet synchronous motors which have the following characteristics compared with the traditional asynchronous motors:
