Abstract: A motor and methods for making and using same. The motor includes a stator having a first stator portion with first and second arcuate regions. The arcuate regions can receive a rotor with a magnetic pole and being concentrically arranged with the stator relative to a central axis. The stator can have one or more winding portions for being wound with a winding and extending from the first stator portion opposite the arcuate regions. When the winding is not energized, a first magnetic coupling between the first arcuate region and a selected magnetic pole is greater than a second magnetic coupling between the second arcuate region and the selected magnetic pole. A selected winding portion is angularly offset from the first arcuate region to advantageously enable movement of the rotor to initiate in either of two opposite directions relative to the selected winding portion when the winding is energized.

Abstract: A power tool includes a main body and a working portion. The working portion is rotatably coupled to the main body. A single phase brushless motor is mounted in the main body to drive the working portion to rotate bidirectionally. In comparison with a traditional motor, the single phase brushless motor make the power tool has a reduced size and reduced cost while ensuring the stable performance.

Abstract: A rolling shutter driving device includes a motor, a locking assembly and a gearbox. The motor includes a stator and a rotor. The rotor includes a rotary shaft connected to the gearbox. The rotary shaft drives through the gearbox a rolling shutter to extend or retract. The locking assembly includes a brake pad slidingly fitted on the rotary shaft and a rotary member fixedly mounted to the rotary shaft. The brake pad is circumferentially fixed relative to the stator. The brake pad is slidable relative to the rotary shaft so as to be selectively engaged with the rotary member to lock the rotary shaft and hence hold the load in position, or disengaged from the rotary member to unlock the rotary shaft.

Abstract: A single-phase brushless motor includes a stator and a rotor rotatable with respect to the stator. The rotor includes a number of permanent magnetic poles. The stator includes a stator core and a winding wound on the stator core. The stator core includes an outer annular portion, an inner annular portion, and connecting portions connecting the inner and outer annular portions. The winding is wound around the connecting portions. The rotor is received in the inner annular portion. The inner annular portion and the rotor form a substantially uniform air gap. A recess is formed in an inner surface of a part of the inner annular portion between each pair of adjacent connecting portions. A center of each recess deviates from a center line of symmetry of the corresponding pair of connecting portions.
