Working Principle
Unlike conventional induction motors, the Air Cooler Permanent Magnet Motor uses high-performance permanent magnets installed on the rotor to generate a constant magnetic field. When electrical current flows through the stator windings, a rotating magnetic field is produced, causing the permanent magnet rotor to rotate synchronously.
Since the rotor does not require induced current, rotor copper losses are eliminated, resulting in significantly higher efficiency and reduced heat generation. Electronic motor controllers precisely regulate motor speed according to airflow demand, enabling intelligent operation and further energy savings.
