摘要： A motor includes a stator, a rotor rotatable relative to the stator, a support member, and a circuit assembly. The circuit assembly includes a plurality of electronic components. The rotor is rotatably mounted to the support member. The stator is received in the rotor. The stator is fixed to the support member, and the support member is at least partially received in an inner side of the stator. A portion of the support member received in the inner side of the stator defines a receiving space, and at least part of the electronic components of the circuit assembly is received in the receiving space of the support member. The support member is partially received in the inner side of the stator, and the circuit assembly is at least partially received in the support member, which makes the motor have a relatively smaller axial size.

摘要： A brushless motor includes a stator comprising a stator core with teeth protruding inwardly and windings wound on the teeth, and a rotor comprising a shaft, a rotor core fixed to the shaft, and a ring magnet fixed to the circumferential outer surface of the rotor core. The ring magnet includes a plurality of magnetic poles radially magnetized so that north poles and south poles are arranged alternately in the circumferential direction, boundary lines between adjacent magnetic poles being skewed by an angle α relative to an axis of the shaft. A plurality of grooves are formed in a circumferential outer surface of the rotor core. Each groove extends from one axial end to the other axial end of the rotor core, has a circumferential width smaller than each of the magnetic poles, and is covered by the ring magnet with a void formed between the groove and the ring magnet.

摘要： A permanent magnet rotor includes a shaft, a rotor core fixed to the shaft, and multiple magnet sets. The rotor core has multiple groove sets for receiving the magnet sets. Each groove set has two grooves spaced apart by a first section of the rotor core. The first section has a width gradually decreasing from a radially inner end to a radially outer end. Each groove has a width gradually increasing from a radially inner end to a radially outer end. Each magnet set includes two magnets respectively received in the grooves of a respective groove set. The magnets of a magnet set are magnetized in a same direction, and every two adjacent magnet sets are magnetized in contrary directions creating multiple magnetic poles. The number of magnetic poles is equal to the number of magnet sets.

摘要： A rotary solenoid (1) includes a stator (10), a rotor (40), and a torsion spring (50) connected between the stator (10) and the rotor (40). The stator (10) includes an armature (13) having three stator poles (14, 15) cooperatively defining a substantially cylindrical space (18) and a coil (19) wound about one of the stator poles (14). The rotor (40) includes a shaft (42) rotatably assembled to the stator (10) and a rotor core (44) fixed to the shaft (42) and received in the cylindrical space (18). The rotor core (44) has three rotor poles (43) corresponding to the stator poles (14, 15). The rotor (40) stays at a first position under the force of the torsion spring (50) and rotates to a second position under the force of the torsion spring (50) and the magnetic force of stator (10) when the coil (19) is powered.

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.
