Abstract: 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.

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 motor, an airflow generating apparatus, and an electric apparatus are provided. The motor includes a stator and a rotor. The stator includes a stator core and stator windings. The stator core includes a ring-shaped yoke and multiple pole portions. A magnetic bridge or slot opening is formed between each two adjacent pole portions. An end surface of each pole portion includes an arc surface. A positioning groove is formed in each arc surface. The arc surfaces of the pole portions cooperatively form a receiving cavity. The rotor includes a rotary shaft and a permanent magnet fixed to the rotary shaft. The permanent magnet is received in the receiving cavity. The arc surfaces are located on a cylindrical surface centered around a rotation axis of the rotary shaft. The cogging torque of the motor can be reduced, thus reducing the startup current and hence the noise of the motor.

Abstract: A load connecting mechanism includes a mounting portion, a contact portion, and a force-exerting portion. The mounting portion is configured to mount the load connecting mechanism to a power source and a load, respectively. The contact portion is disposed on the mounting portion and includes two slidably coupled contact faces. The force-exerting portion is configured to provide a force to the contact faces in an axial direction of the power source to make the contact faces closely slidably couple to each other. Through the slidable coupling relationship between the contact faces, power of the power source is progressively transmitted to the load and finally drives the load to rotate in synchronization with the power source. The present invention further provides a motor driving assembly and a fan. The mechanism can satisfy the needs of bidirectional rotation of a load such as a fan and of large startup torque.

Abstract: A PMDC motor includes a housing, a stator magnet fixed to the inner circumferential surface of the housing, a rotor core received in the housing and facing the stator magnet, and rotor windings wound around the rotor core. The rotor core includes a plurality of rotor teeth, each of the rotor teeth including a tooth body and a tooth tip. A ratio of the outer diameter of the rotor core to an outer diameter of the housing is in the range of 0.6 to 0.67. Compared to the existing PMDC motor, the PMDC motor of the present invention can satisfy the same performance requirement, while reducing the size and weight of the rotor core and hence the weight of the rotor windings. In this way, the total weight and hence the moment of inertia of the rotor is reduced, thereby effectively reducing the noise generated during operation of the motor.
