摘要： A disk drive apparatus reproduces a signal from a disk and/or records an signal on the disk. A position detecting part produces a position signal in response to a rotation of a rotor. An activation operation block controls active operation of first and second power amplifying parts in response to the position signal. A signal producing part produces a slope signal which repeats a slope waveform a plural times during one period of the position signal. The shaping part produces first and second activation control signals which responds with the slope signal. The activation operation block controls the first and second power amplifying parts responding with the first and second activation control signals. Therefore, an excellent disk drive apparatus with reduced acoustic noise and reduced vibration can be realized by using only one position signal of one position sensor.

摘要： Power transistors of a power supplying part execute high-frequency switching operation and form current paths to three-phase windings so as to rotate the disk. A voltage detecting part produces a detected pulse signal responding with terminal voltages of the three-phase windings. An activation operation part controls active periods of the power transistors in response to the detected signal. A phase detecting part includes a slant producing part and a phase pulse producing part. The slant producing part produces a slant voltage signal which intermittently responds with a voltage difference between one of the power supplying terminal voltages and the common terminal voltage of the three-phase windings and has a voltage slant. The phase pulse producing part produces a phase pulse signal by comparing the slant voltage signal with a reference voltage. A commanding part produces a command signal which responds with the phase pulse signal. A switching operation block causes at least one of the power transistors to perform high-frequency switching responding with the command signal.

摘要： In a motor and a disk drive apparatus using the motor, a switching control part produces a PWM pulse signal in response to the comparison result between a current detected signal and a command signal. An activate control part determines the active periods of power transistors in response to the holding state of the state holding part, and performs high-frequency switching operation to turn ON/OFF the power transistors in response to the PWM pulse signal of the switching control part. Furthermore, a voltage detecting part stops the detection of terminal voltages for a predetermined time in response to the PWM operation by the switching control part. After the stop, the voltage detecting part resumes the detection of the terminal voltages. This prevents improper detection caused by PWM noise.

摘要： A disk drive apparatus reproduces an information signal from a disk with a head, and outputs a processed information signal from the reproduced signal of the head. A movable member having a field part which generates field fluxes is coupled to the disk so as to rotate the disk directly. First FET power transistors of first power amplifying parts and second FET power transistors of second power amplifying parts form current paths from a DC power source to three-phase windings. Three-phase first amplified current signals varying smoothly in rising and falling slopes are supplied to conduction control terminal sides of the first power amplifying parts. Three-phase second amplified current signals varying smoothly in rising and falling slopes are supplied to conduction control terminal sides of the second power amplifying parts. A switching operation block performs simultaneous on-off switching of the conduction control terminal sides of the first power amplifying parts, thereby causing first FET power transistors of the first power amplifying parts to perform high-frequency on-off switching. The switching operation block changes a peak of a pulsive conducted current signal from a DC voltage source to the three-phase windings responding with or corresponding to a rotation of the disk. As a result, three-phase drive currents to the windings vary smoothly, and the disk drive apparatus reduces a vibration and an acoustic noise of the disk. Further, the disk drive apparatus reduces a power consumption and a heat to the disk.

摘要： A full wave drive brushless DC motor system detects zero-crossing points of counter electromotive forces respectively induced by the stator windings, and then pulse-shapes the thus detected zero-crossing points to obtain a pulse signal train, and then measures the thus obtained period of the pulse signal train to determine a conducting phase of the stator windings in response to the thus counted period. The system is thereby capable of supplying an electric current bidirectionally to each of the stator windings without using a position sensor for detecting a position of a rotor.
