Zusammenfassung:The invention provides a wheel-type motor and a walking-beam pumping unit adopting the motor. The motor mainly comprises a motor housing, a stator core, a motor end cover, a winding, a magnet, a hollow shaft, a rotor yoke and a rotor yoke support plate. The wheel-type motor eliminates the disadvantages of low belt transmission efficiency, large belt loss and periodic belt maintenance and replacement of the walking-beam pumping unit, and has the advantages of high efficiency and no maintenance. 本发明提供种轮式电动机及采用该电动机的游梁式抽油机,所述电动机主要包括:电机机壳、定子铁芯、电机端盖、绕组、磁铁、空心轴、转子磁轭、转子磁轭支撑板。根据本发明所述的轮式电动机,消除了游梁式抽油机皮带传动效率低,损耗大,且皮带需要定期维护更换的缺点,具有高效、免维护的优点。
