A motor drive system includes an electric motor including a rotor shaft, a first main winding and a second main winding. The first and second main windings are selectively energizable to operate the motor at first and second speeds, and at least one of the windings is a permanent split capacitor winding. A transmission is coupled to the rotor shaft, and the rotor shaft engages the transmission without employing a clutch mechanism.
