Permanent magnet synchronous motor (PMSM)

Permanent magnet synchronous motor (PMSM) is a kind of rotary AC synchronous motor, like any rotating electric motor, consists of a rotor and a wound stator. The rotor consists of permanent magnets. Permanent magnets located on the rotor create a constant magnetic field. The magnetic field of the rotor, interacting with the synchronous alternating current of the stator windings, creates torque, forcing the rotor to rotate at a synchronous speed with the stator field.

JPM series Ultra High Efficiency Rare-earth Permanent Magnet Synchronous Motor adopts interior permanent magnet rotor, not only has ultra-high efficiency, but also has features such as simple structure, reliable, small size, low weight and good interchangeability etc. JPM series Ultra High Efficiency Rare-earth Permanent Magnet Synchronous Motor is driven by frequency inverter through encoder-free vector control. Within the range of 25%-125% load, compare with same size asynchronous motor, it has higher efficiency, wider economic range, lower temperature rise and significant energy-saving.
