Permanent magnet direct drive motor-Jiangsu Hengchi Motor Technology Co., Ltd

Compared with induction motors, permanent magnet direct drive motors do not require reactive excitation current, which can significantly improve power factor, reduce stator current and losses, and have no rotor resistance loss during stable operation. Therefore, while reducing total losses, they can reduce fan and corresponding wind friction losses, resulting in an efficiency improvement of 10-15 percentage points compared to induction motors of the same specification. In addition, permanent magnet synchronous motors can maintain high efficiency and power factor within the range of 25% to 120% of rated load, making their energy-saving effect more significant during light load operation.

Compared with other types of motors, permanent magnet direct drive motors have higher power, mass ratio, and smaller size, therefore they will play a greater advantage in the use process. In addition, for motors, their speed and braking performance are also very good. This usage characteristic is also one of the main reasons for the high attention of permanent magnet direct drive motors in the market. However, if the material vibrates during normal use, the permeability may decrease under the action of high temperature and overload current. In this case, demagnetization can only occur, which may reduce the performance of permanent magnet direct drive motors.

The application of permanent magnet synchronous motors in the field of industry and agriculture is gradually widespread, and it can be said that they have been very popular.
