摘要： A controller of a brushless DC electric machine having a rotor and at least a stator winding powered by a driving voltage is provided. The controller includes a position sensor, an advance angle control circuit, and a driving circuit. The position sensor is moved along a reverse rotating direction of the rotor by a prepositioned angle for outputting a position signal. The advance angle control circuit receives the position signal and a driving voltage reproduction signal reproduced from the driving voltage and outputs a commutation control signal lagging the position signal by a first delay time. The driving circuit receives the commutation control signal for outputting a driving signal for controlling a commutation of the brushless DC electric machine.

摘要： A rotary structure of a permanent magnet electric machine including a stator and a rotor is provided. The stator has K salient teeth peripherally spaced with equal intervals for forming K winding slots, wherein K is a natural number greater than 1. The rotor has an annular inner surface and has P pairs of permanent magnets peripherally spaced with equal intervals along the inner surface for rotating around the stator, wherein P is a natural number. Each permanent magnet having two sides along a peripheral direction of the rotor includes a pair of inclined surfaces on the two sides, the pair of inclined surfaces is symmetric with respect to a radial plane of the each permanent magnet, and an inclined angle α between the inclined surface and the radial plane is selected from a range of 90(1−1/(4P))

摘要： A motor includes a first housing, a second housing, a rotor and a stator. The second housing is assembled with the first housing to form an accommodating space. The second housing has a flange adjacent to the connection between the first and second housings. The rotor has a shaft extended outwardly from the second housing and disposed in the accommodating space. The stator is disposed corresponding to the rotor and in the accommodating space. The flange has at least one protruding portion. When the second housing is assembled with the first housing, the protruding portion presses against the stator and is deformed so that the first and second housings are sealed.
