Product introduction

PMSM has the advantages of simple structure, small size, high efficiency and high power factor.

The permanent magnet synchronous motor adopts centralized winding, optimal pole slot coordination, and rotor structure integrating isolation, stress, positioning and lightweight, with small rotational inertia, small leakage flux, large main flux, higher power factor and higher efficiency. The torque amplifier coupled with the permanent magnet motor (planetary reducer) has the characteristics of increasing the output torque, matching the load inertia, and exclusive use of multi-tooth meshing. Under the control of frequency converter, when the permanent magnet motor is interconnected with multiple machines, it is easy to realize power balance control due to the soft mechanical characteristics.
