摘要： A spindle motor for a disc drive, such as a CD-ROM drive, is provided. This spindle motor is a brushless motor of a single-phase axial-winding and radial-gap type including a stator, a rotor coupled to said stator, and a driving circuit for supplying a driving signal to the stator to rotate the rotor. The stator includes a pair of upper and bottom salient-pole pieces formed with a plurality of tooth-like portions serving as salient-poles. The peak surface of each tooth-like portion is formed into a symmetrical convex shape, which minimizes the cogging torque of the motor. Further, the use of a phase-adjuster in the driving circuit allows the motor to produce large output torque at high speeds. The output characteristics of this spindle motor meet the requirements of high speed CD-ROM drives.

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 method for designing an optimal bi-axial type of magnetic gear system that uses magnetic coupling for transmitting torque in order to be free from the defects caused by using a conventional mechanical gear system. A non-coaxial rather than a conventional coaxial type of magnetic gear design is considered for this invention. For the non-coaxial magnetic gear system, the size of torque will depend on the number of poles magnetized out of the strong magnetic material around the magnetic gear. Therefore, the optimum number of magnetized poles must be carefully selected for a set of specified conditions such that the largest torque can be obtained. An optimal magnetic gear system can be produced by the method in this invention.

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.

Receive magnetic signals generated by the magneto-resistive sensor of the linear actuator, which include a sine signal and a cosine signal.

摘要： A method for measuring the electromotive force of motors is provided. The method enables the motor to rotate in single phase mode, and thereby measures the electromotive force constant of the motor. According to the principles and the method, motors do not have to work in close-loop. Neither encoders for detecting angle displacement or angle velocity are needed for motors, nor the motor impedance or current have to obtain in advance. Compared with the prior art, the disclosed method is more efficiency and economic.
