Permanent magnet Synchronous motor
Permanent magnet Synchronous motor is a type of motor that utilizes a permanent magnet to generate a magnetic field and control it. Its characteristics are:
High magnetic flux density: Due to the use of high-performance permanent magnet materials, the magnetic flux density of PMSM is several times higher than that of ordinary induction motors, thereby improving the efficiency and power density of the motor.
Good speed regulation performance: The speed of PMSM can be adjusted by controlling the current frequency of the stator, achieving a wide range of stepless speed regulation.
High operating efficiency: Due to the use of permanent magnet materials, the iron loss and copper loss of the motor under rated load are reduced, thereby improving the operating efficiency of the motor.
High reliability: Due to its simple structure and fewer rotating parts, PMSM has high reliability and low maintenance costs.
Environmental protection: Due to its high efficiency and low noise, PMSM has been used as the preferred alternative to DC and AC induction motors in many fields.
In addition, permanent magnet Synchronous motors also have strong overload capacity and excellent starting performance. In many modern equipment and systems, such as CNC machine tools, robots, electric vehicles, etc., permanent magnet synchronous motors can be seen.
