摘要： The present invention provides a three-phase motor stator. The shape of the three-phase motor stator is defined by an optimum pole-tooth ratio for reducing the cogging torque of the motor and increasing the efficiency of the motor. The three-phase motor stator includes at least one plate board. The plate board has a circular hole. A plurality of pole-teeth protrude from the rim of the circular hole and the pole-teeth are symmetric. An opening slot is individually located between two adjacent pole-teeth. The pole-tooth ratio α defined by the tooth angle of a single pole-tooth divided by the pole pitch of two adjacent pole-teeth is between 0.65 and 0.85.

摘要： The invention pertains to a method for determining whether a rotor is good in magnetic induction by measuring the electromotive force (emf) of a motor. A standard stator of the motor is prepared as the standard of measurement. A set of induction coil is wound upon the standard stator so that when the rotor is combined with the standard stator and is subject to running by a driver, the induction coil can detect the back-emf signal generated by the rotor, by which the rotor quality can be determined. Since the measuring method disclosed in the invention is performed within the closed system composed of the rotor and the stator, the result is not only close to a real motor in rotation, the detection is simple and free from the problem of axis alignment. Thus, this method can increase the production efficiency of the product line.

摘要： The present invention is a starting method for brushless DC motor and a device for the same, especially adapted to provide the starting method for a single-phase DC brushless motor in an open circuit and the device for the same. According to the art as disclosed in the present invention, there are two successive steps in starting a motor. An oscillator signal is transmitted to the driver at first, which causes the motor to oscillate in both clockwise and counter-clockwise direction. An operating signal is then sent to cause the motor to rotate normally in one direction once the motor is out of the dead initiating position. By that the rotor can be triggered out of the dead initiating position when the motor is going to start and the motor can be smoothly operated under the low cogging torque.

摘要： A sensorless driving method for a brushless DC motor is provided. The time for the motor to rotate an electrical angle 60° is obtained by alternatively counting the occurrences of zero crossings with two counters and comparing the counted values, and the motor is delayed an electrical angle of 30°, by which a precise commutating time is obtained. The driving method provides a mask-based phase shift digital detection mechanism for effectively detecting true zero-crossing points. The driving method further provides an inhabitation mechanism with the function of soft-switch for inhibiting noise caused by transistor switching. By using these two counters, the time for the motor to rotate two electrical angles 30°−Δθ and 30°+Δθ are obtained and stored in two registers. The time period before and after the commutating point is added into a pulse width modulation (PWM) signal to reduce the noise and vibration.
