摘要： A PMDC motor has a housing, a stator magnet disposed in an interior of the housing, and a rotor core disposed within the stator magnet. A ratio of an outer diameter of the rotor core to the outer diameter of the housing is from 0.60 to 0.67. The noise of the motor during operation is reduced by increasing the thickness of the stator magnet, reducing the outer diameter of the rotor core, reducing the air gap between the magnet and the rotor core and reducing the rotational inertia of the rotor core. The motor is particularly suited for use in vehicle HVAC systems where low noise is an important requirement.

摘要： 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.

摘要： A single phase permanent magnet motor includes a stator and a rotor. The stator includes a stator core and a stator winding. The stator core includes an outer yoke, teeth extending inwardly from the outer yoke, and pole shoes extending from inner ends of the teeth. The rotor is received in a space cooperatively defined by the pole shoes. The rotor includes circumferentially arranged permanent magnetic poles. An outer circumferential surface of the permanent magnetic poles is concentric with an inner circumferential surface of the pole shoes, such that a uniform air gap is formed between the pole shoes and magnetic poles. The single phase permanent magnet motor forms the uniform air gap, which reduces the vibration and noise. The pole shoes form invisible positioning slots, which avoids the negative effect of the positioning slots to the thickness of the air gap and reduces the startup dead point.

The stator core includes a plurality of stator teeth each including a tooth body and a tooth end formed at an end of the tooth body, the tooth end comprising first and second arcuate regions facing the rotor. When the winding is not energized, a first magnetic coupling between said first arcuate region and a selected magnetic pole of said rotor is greater than a second magnetic coupling between said second arcuate region and the selected magnetic pole, said first arcuate region being offset from a selected tooth body in such a way as to enable movement of said rotor to initiate in either of two opposite directions relative to said selected tooth body upon energizing the winding.

摘要： A magnetic core for an electric motor has a ring-shaped yoke, teeth extending outwardly from the yoke, and a tooth tip extending from a distal end of each tooth. The core is formed from curved or coils strip laminations having teeth arranged in tooth groups. Each group has four tooth types arranged sequentially. Each tooth has left and right half tooth tips. The length of the half tooth tips vary according to tooth type. When assembled, first type tooth overlap with third type teeth and second type teeth overlap with fourth type teeth, whereby the opening of the winding slot is narrowed compared to laminations having all identical teeth.

摘要： A single phase permanent magnet motor includes a stator. The stator includes a stator core and windings. The stator core includes a ring portion, tooth bodies extending radially from the ring portion, and a pole shoe extending from a distal end to two circumferential sides of each tooth body. Each pole shoe defines a positioning slot. A center of each positioning slot is offset from a center of symmetry of one adjacent tooth body so that a torque fluctuation of an output torque of the single phase permanent magnet motor during operation is less than 50%. As a result, the motor vibration and noise are small.

摘要： 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.
