Abstract: AC motor driving system and driving method thereof are provided. The driving system and method are capable of increasing power factor, adjusting waveform of the DC ripple voltage for increasing driving efficiency. The driving system is basically constructed by connecting three circuits. The first circuit is a three-phase full wave rectifying circuit and is used to transfer commercial electricity to a first DC voltage. Then, the second circuit is used to transfer the first DC voltage to a second DC voltage that ripples voltage thereof having a semi-sinusoidal waveform. The third circuit is an AC driving circuit, and receives the second AC voltage for driving the AC motor. Thereby, the driving efficiency can be increased. The capacitance used in the present disclosure has low capacitance value, thus the power factor can be increased, and usage time of the AC motor driving apparatus can also be increased.

Abstract: An angle detecting module for a motor rotor is provided. The angle detecting module includes a permanent-magnet synchronous motor, three linear hall components and a processing device. The permanent-magnet synchronous motor includes a stator and a rotor. The three linear hall components are disposed on the stator; and the linear hall components are spaced by electrical 120 degrees. Each of the linear hall components outputs an analog signal after measuring a magnetic field position of the rotor, and each of the analog signals has magnetically saturated third harmonic component. The processing device is electrically connected to the linear hall components, and the processing device optimizes each of the analog signals and generates an average rotor angle.
