摘要： 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.

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