Claim 16:
17. A motor starter comprising:
a plurality of switches configured to selectively connect phases of an AC power source to phases of motor; and
a control circuit configured to operate the plurality of switches to connect pairs of phases of an AC power source to pairs of phases of the motor in a first sequence that repeats at a first frequency to thereby drive the motor and to operate the plurality of switches to connect pairs of phases of the AC power source to pairs of phases of the motor in a second sequence that is reversed with respect to the first sequence and that repeats at a second frequency less than the first frequency to thereby brake the motor, wherein the control circuit is configured to cause the plurality of switches to disconnect all of the phases of the motor from the AC power source for a predetermined dwell interval before initiating the second sequence.
