Permanent magnet motor KYT series (IP55) compressor special ultra-efficient permanent magnet variable frequency motor Frame center height: H160 ~ H355 Rated output power: 15kW ~ 250kW This series of motors uses permanent magnet motors made of rare earth permanent magnet materials. The rotor has achieved rare earth permanent magnetization, no slip, no fundamental iron in the rotor, copper loss and less heat generation, which reduces stator current and stator resistance losses. Especially at low speeds, high motor efficiency can still be maintained.
