CONTROLLABLE ELECTRIC DRIVE WITH SWITCHED MOTOR FOR SUBMERSIBLE OIL PUMPS

摘要

Electric drives with a magnetoelectric switched motor are described. The motor structure is considered, along with the results of electromagnetic calculation by the conformal-mapping method. The calculations and experiments indicate that a stepless switched motor with natural commutation may be produced, making better use of active materials than for a frequency-regulated asynchronous motor of analogous type.
