Three phase asynchronous motors are often used to drive oil-pumping units.Operating at a very low load factor motors are running at low efficiencies and low power factors with a lot of energy wasted. The Rare Earth Permanent Magnet(REPM)synchronous motors developed by the authors found an application in the field of motor energy-saving in oil-pumping units. In the paper introduced are the energy saving mechanism, key techniques applied and the field testing results in oil-pumping units. Great energy-saving benefits can be achieved by using REPM motors to drive in oil-pumping units and this kind of motors will find a wide application in oil fields.
