Permanent magnet synchronous motors (PMSM) are an important technological innovation in the field of electric motors, which have attracted attention for their high efficiency, sustainability, and low maintenance costs. In this paper, we will provide an in-depth introduction to what a permanent magnet synchronous motor is, and discuss its performance, wide range of application areas, and future development trends.
Ⅰ. Introduction to Permanent Magnet Synchronous Motors
A permanent magnet synchronous motor is a type of synchronous motor characterized by a rotor equipped with permanent magnets and these permanent magnets produce a fixed magnetic field. When current passes through the stator windings, the resulting magnetic field interacts with the magnetic field of the permanent magnets, causing the motor to rotate. This synchronization ensures that the motor is highly efficient, as the rotor and magnetic field remain synchronized, reducing energy losses.
