摘要： An apparatus for data transfer with a magnetic disk having a diameter of, say, 86 millimeters, having a pair of transducer heads for data transfer engagement with the opposite surfaces of the disk mounted on a turntable driven directly by a disk drive motor. In order to hold the magnetic disk exactly level on the turntable for proper data transfer contact with the transducer heads, a leveling mechanism is provided whereby at least the turntable is made adjustably movable in its axial direction with respect to the frame of the apparatus, as by the manual turn of an adjusting screw or screws. In one embodiment, the turntable is movable with a drive spindle on which it is mounted coaxially and which forms an output shaft of the disk drive motor. In another embodiment, the turntable travels with the complete disk drive motor.

摘要： In a stepping motor of the type having one or more sets of four phase windings on respective stator poles, with the four phase windings being excited sequentially to cause the rotation of a rotor having magnetic poles, a drive method and system are disclosed for stopping the rotor in exact angular positions required. Since the stator can less magnetically control the rotor when the latter is positioned with its magnetic poles in axact alignment with the stator poles, the stator windings are sequentially excited in such a manner that upon termination of the sequential excitation, the rotor comes to a stop in a position angularly displaced to a predetermined degree in a predetermined direction from a position of exact alignment with the stator poles. Basically, for stopping the rotor in such angular positions, at least two of the four phase windings are excited at a time with currents of predetermined different magnitudes.

摘要： A drive method and system are disclosed for a stepping motor typically having several sets of four phase windings on respective stator poles of annular arrangement, and a rotor having several alternating N and S poles at constant circumferential spacings. Normally, the windings are sequentially excited as by a single or two phase drive mode to cause the rotor to rotate by increments. For stopping the rotor in a required angular position, any one or two of the four phase windings are excited in a normal direction to polarize the associated stator pole or poles into one polarity to attract one of the opposite poles of the rotor. Further, the other phase windings on both sides of the noted one or two windings are excited in the reverse direction, as by the discharge of capacitors, with the consequent polarization of the associated stator poles into the opposite polarity. The stator poles thus polarized into the different polarities make possible the positive detenting of the rotor in the required angular position.
摘要翻译： 公开了一种用于步进电机的驱动方法和系统，该步进电机通常在环形布置的相应定子极上具有若干组四相绕组，以及具有恒定圆周间隔的几个交替的N极和S极的转子。 通常，通过单相或双相驱动模式顺序地激励绕组，以使转子以增量旋转。 为了将转子停止在所需的角度位置，四个相绕组中的任何一个或两个在正常方向上被激励，以将相关联的定子极或极极化成一个极性，以吸引转子的相反极中的一个。 此外，所指示的一个或两个绕组的两侧的其它相绕组在反向方向上被激励，如通过电容器的放电，相关的定子极的相应的极化相反。 因此，极化为不同极性的定子极可能使转子在所需角度位置的正向定位。

摘要： There is provided a single-phase AC synchronized motor that does not need smooth of rectifier waves but stably performs shift from a starting operation to a synchronized operation. In the motor, based on detected signals of a position sensor, rectified current is reciprocally flowed to each direction of a single-phase coil which starts the motor. The motor includes a start-up operation circuit with a sensor starting period that increases a rotational speed until reaching to a first predetermined rotational speed; and a control device that controls operation of the motor as that shift to synchronized operation is performed when a rotational speed of a permanent magnetic rotor is reached to a second predetermined rotational speed nearby a synchronized rotational speed but not exceeding the synchronized rotational speed, and when the rise and fall of detected signals of the position sensor and the zero-cross point of AC current are approximately correspondent to each other.
