Flexible starting mode setting, and meeting the requirements of different starting conditions and running conditions. The axial length of the electric roller under the well is shortened, and the electric roller is suitable for narrow space under the well. Compared with an asynchronous motor with synchronous rotating speed, the permanent magnet synchronous motor reduces a slip ring and a regulator excited by a rotor, and has no excitation loss. Within the range of 25% -100% of load, the asynchronous electric roller has higher efficiency, wide economic operation range and obvious energy-saving effect compared with the asynchronous electric roller with the same specification. The temperature rise of the electric roller is low, the temperature rise of the electric roller is 50-60K under rated load, and compared with the common electric roller, the electric roller adopts the effect, and the composite magnetic system formed by the permanent magnetic blocks has high magnetic field intensity, so that the magnetic field can be maintained without external energy.
