摘要：

The low-speed efficiency of an induction motor is improved by rectifying slip-frequency power, inverting this to line frequency, and injecting it back into the supply directly (line feedback) or through auxiliary stator windings (stator feedback). Torque-speed curves then have the nature of a variable-speed drive. The low power factor and nonsinusoidal supply current of the line feedback connection are improved by use of the stator feedback method but the improvement of efficiency is then much less. Line feedback with a two-phase induction motor eliminates the need for a variable control voltage source. Copyright © 1969 by The Institute of Electrical and Electronics Engineers, Inc.
