The core power of energy-saving large fans is permanent magnet synchronous motors (mainstream), and some entry-level models use optimized asynchronous motors.
Analysis of Core Power Unit
Permanent magnet synchronous motor is the mainstream choice, which generates a magnetic field through permanent magnets without the need for additional excitation current and has high energy conversion efficiency.
Compared to traditional asynchronous motors, its efficiency can be improved by 10% -30%, and it can output high torque at low speeds, meeting the working requirements of energy-saving large fans with "low speed, large diameter, and wide coverage".
The motor is equipped with variable frequency speed regulation technology, which can adjust the speed according to the scene, further reducing energy consumption while ensuring smooth operation.
Auxiliary advantages of power system
Compact structure and small volume, reducing the overall weight of the fan and lowering installation and operational loads.
Low operating noise, suitable for noise sensitive scenarios such as factories, warehouses, supermarkets, etc.
Long service life, stable performance of permanent magnets, reducing maintenance frequency and costs.
