Our permanent magnet motor is a fully enclosed rare-earth permanent magnet synchronous motor featuring high overload capacity, high efficiency, high power factor, smooth operation, simple maintenance, and strong interchangeability. It combines the advantages of both asynchronous and conventional synchronous motors. The cooling methods are IC416/IC411, with a duty type of S1. The installation method complies with IEC and DIN standards, ensuring international compatibility.
- Premium Materials: By using rare-earth materials, the motor offers higher overload capacity, greater efficiency, and more stable operating performance.
- Optimized Design: Three-phase permanent magnet motor features low inertia, a wide operating frequency range, and smooth torque output at low speeds.
- Standard Enclosure: Adopts a standard enclosed structure to maintain stable operation under various extreme working conditions.
- Energy Efficiency: Prevents rotor heating and power loss, achieving higher energy efficiency and lower operating costs (IE5 level).
- Low Maintenance: Maintenance-free operation, widely used in mining, power plants, steel mills, and water treatment.
- Reliable Performance: Sufficient design margin ensures low temperature rise during full-load operation. Ideal for OEM/ODM requirements meeting European IEC standards.
