Abstract: The present invention relates to an integral or a non-integral stator structure for reducing the manufacturing complexity by eliminating the boot part of the tooth part thereof. The stator structure is made of a core material, and includes: a plurality of stator units, each having a tooth part and an annular part, in which different stator units can be connected with each other integrally or non-integrally, so as to form an annular stator structure. The tooth part of each stator unit is formed in a pillar shape that has a first end and a second end, and the first end is connected to the annular part.

Abstract: A composite permanent magnet synchronous machine includes a permanent magnet synchronous machine module having a rotor unit and a stator unit; a bottom base having an accommodation space; a top cover having a front surface; and a shaft penetrating through the front surface. The rotor unit has P rotor magnets and the stator unit has S slots, wherein a tooth part is defined between every two adjacent slots, and a coil is wound on the tooth part, where P is 38N, S is 36N, and N is a positive integer; or P is 34M, S is 36M, and M is a positive integer. The machine is suitable for wind power generators or any other machine structure.

Abstract: A digitized method for generating pulse width modulation (PWM) signals is disclosed. In the digitized method, multiphase PWM signals are generated by altering the reference levels so that fully on duty cycle or fully off duty cycle of each phase PWM signal can be achieved. Therefore, the digitized PWM signal generation method in the present invention can be applied to any application apparatus having boost/buck converter.
