Advantages of permanent magnet synchronous motor：
1. Small torque ripple, stable speed, fast and accurate dynamic response, strong overload capacity< br> (1) When the load torque of an asynchronous motor changes, it is required that the slip rate of the motor also changes accordingly, that is, the speed of the motor changes accordingly. However, the inertia of the rotating parts of the system hinders the speed of the motor response.
(2) When the load torque of a synchronous motor changes, as long as the power angle of the motor changes appropriately and the speed remains unchanged at the original speed, the inertia of the rotating parts will not affect the motor's rapid response to torque.
2. High power factor, high efficiency
(1) Permanent magnet synchronous motors can eliminate the need for reactive excitation current, significantly improving power factor and reducing stator current and copper losses.
(2) During stable operation, there is no rotor copper loss due to the absence of rotor bars.
(3) Reducing the fan capacity or even removing the fan due to the decrease in total loss reduces the corresponding wind friction loss.
(4) Its efficiency can be improved by 2-3% compared to asynchronous motors of the same specifications.
(5) The power factor is above 0.9, close to 1, and its no-load current is very small, only a few amperes.
3. Small size and light weight.
Its volume and weight are 20-30% lighter than asynchronous motors of the same capacity.

Disadvantages of permanent magnet synchronous motors：
1. Due to the influence of magnetic force, it is difficult to disassemble and assemble motors, calibrate dynamic balance, and assemble magnetic steel, which brings great difficulties to the manufacturing and maintenance of motors.
2. In order to reduce the leakage magnetic field, the motor rotor requires safe and reliable magnetic isolation measures. Generally, aluminum plates, copper plates, epoxy resin, glass cloth plates, air, etc. are used for magnetic insulation.
3. Permanent magnet magnetic service life, magnetic decay period, and environmental factors affecting the service life of permanent magnets.
(1) Under normal use, the magnetic force of permanent magnets has been used for more than 25 years.
