Abstract:
Electric motors and drive circuits therefor are described herein. The
drive circuit is configured to operate in a first mode of operation and a
second mode of operation. The drive circuit includes an inverter
configured to regulate current to a first winding and a second winding of
the electric motor in the first mode of operation and to only the first
winding in the second mode of operation. The drive circuit also includes
a first switch coupled to the second winding and configured to supply
line frequency current to the second winding at a first node in the
second mode of operation, and a second switch coupled to the second
winding and configured to enable selection of regulating current to the
second winding using the inverter in the first mode of operation or
supplying the line frequency current directly to the second winding in
the second mode of operation.Claims:
