Product Description
        Ningbo Tianan Group's R & D department developed magnetic drive permanent magnet motor complex, using a magnetic field modulation principle, the low-speed rotation of the rotating magnetic field magnetic field modulation to achieve low speed high torque output. Torque density of 80 ~ 120kNm / m3. Less than the same volume of the gearbox torque specifications.
        The main factors that determine the size of the volume of motor torque rather than power. Torque density ordinary permanent magnet synchronous motor is generally 20 ~ 50kNm / m3, and the general need to take special measures to cool the high torque density. If the permanent magnet synchronous motor directly replace the ordinary induction motor, pulley and gear box, drive beam pumping unit, the volume will exceed the motor torque specifications with mechanical reduction gear box.
        Permanent magnet motor can be complex using a common non-coding inverter control.

        1, Small size: permanent magnet motor composite structure is compact, with the torque does not exceed the specifications of mechanical reduction gear box. It can be installed directly in the transformation of traditional beam pumping unit on.
        2, High efficiency: permanent magnet motor complex not only has a very compact structure, but without any cooling measures, its efficiency is still very high efficiency rating of over 90%, the average efficiency of 25% or more within a load range of 85% also.
        3, Low noise: optimized process design and electromagnetic, permanent magnet motor complex quiet and smooth. For direct drive beam pumping unit, especially for the family area, landscape area, urban area oil fields.
        4, High power factor: Permanent Composite Motor rated power factor in itself is more than 95% in the entire operating region, including the drive, including the average power factor is also more than 70%. Effectively improve the comprehensive energy-saving rate of the system, reducing the equipment capacity and line losses.
        5, Temperature: under natural cooling conditions, the temperature rise of the permanent composite motor does not exceed 40K, to ensure that the composite permanent magnet motor long life and stable operation.
        6, Maintenance-free: the permanent reduction in the composite motor drive links and improve system efficiency and reduce the system failure rate, and the need to replace the oil, to improve the reliability of the equipment, increase the continuous working time of the device.
        7, Self-protection: the composite permanent magnet motors provide multiple protection. In addition to the drive to provide overvoltage overcurrent protection, but itself has overload protection function.
