摘要：

The causes for fluctuations in instantaneous speed of contactless dc motors have been investigated. It is shown that elimination of overlap in operation of the transistor commutator switches permits a ten- to twentyfold reduction in the electromagnetic torque due to the nonuniformity of the distribution of electromagnetic torque over the angle of rotation of the rotor. Recommendations are given for improving smoothness of operation. Refs.
