Abstract
Reversible motor including a stator having two windings (a–a', b–b′), a start apparatus (c–c′) connected to one of the two windings (a–a′, b–b′) in series, switches () for providing power to the two windings selectively, wherein the switches, for reversing the motor, are connected selectively such that the direction of the current in the one of the two windings is reversed and the start apparatus is connected to the other one of the two windings in series, and a turns ratio and a cross section area ratio of the two windings being adjusted for a sufficient start torque and an optimal efficiency of the reversible motor.
