    • A motor (100) and methods for making and using same. The motor (100) includes a rotor (200) including magnetic poles and a stator (300) comprising a stator core and a winding wound on the stator core. The stator core includes a plurality of stator teeth each including a tooth body (320) and a tooth end formed at an end of the tooth body (320), the tooth end comprising first and second arcuate regions (311A, 311B) facing the rotor (200). When the winding is not energized, a first magnetic coupling between said first arcuate region (311A) and a selected magnetic pole of said rotor (200) is greater than a second magnetic coupling between said second arcuate region (311B) and the selected magnetic pole, said first arcuate region (311A) being offset from a selected tooth body (32) in such a way as to enable movement of said rotor (200) to initiate in either of two opposite directions relative to said selected tooth body (320) upon energizing the winding.

    • A drive circuit for an electric motor having a wound stator (12) and a permanent magnet rotor (14), includes a controllable bidirectional AC switch (28) connected in series with a stator winding (16) between two terminals for connecting to an AC power supply (26). First and second position sensors (20, 22) detect the position of magnetic poles of the rotor. A voltage regulating circuit (30) is connected between the two terminals and the controllable bidirectional AC switch (28) and configured to supply power to the first sensor (20) during the positive cycle and to the second position sensor (22) during the negative cycle of the AC power supply such that the controllable bidirectional AC switch (28) is switched between a conductive state and a nonconductive state in a preset manner, thus enabling the stator (12) to rotate the rotor (14) in only one predetermined direction during start-up.
