摘要： A motor driving control device includes a motor, a switch unit that controls driving of the motor, a current detection resistor that outputs a detection voltage indicating a current of the motor, a comparator that compares the detection voltage with a target current value, an on signal generating unit that generates an on signal, a polarity of which is changed for each interval of predetermined time, and a control unit that has the comparator, a holding circuit receiving the on signal to change a circuit state. When a change in polarity of the on signal is detected, the holding circuit holds the circuit state such that the switch unit is turned on and a current is supplied to the motor. When the comparator detects that the current of the motor is increased to the target current value, the holding circuit holds the circuit state such that the switch unit is turned off.

摘要： A motor includes a casing and a holder which support a rotation shaft. A concave groove is formed in the holder near the inner periphery of the holder. The concave groove accommodates a positive temperature coefficient thermistor functioning as an overcurrent protection device. A tapered cutout surface is formed on the outer wall of the holder so that the cutout surface is inclined at 45 degrees with respect to a line passing through the rotation shaft and the groove portion of the holder has a maximum length of the holder in its axis direction. A multi-direction input device includes these two motors functioning as driving sources to provide a force feedback to an operation lever. The first and second motors are disposed such that lines passing through their rotation shafts are orthogonal to each other and cutout surfaces are opposed to each other with an intersection of the lines therebetween.

摘要： A floppy disc drive device including a drive arm held as a result of being attracted upward. Both ends of the drive arm are loosely suspended from a rotor yoke. A drive pin is formed on the front portion of the drive arm. It loosely passes through a drive pin through hole formed in the rotor yoke. It is loosely inserted into a hole formed in the center hub. At a back edge, defining the drive pin through hole and formed so as to come into contact with the drive pin, is formed a guide path, a side of which gradually inclines backwards as it extends away from the center of rotation of the rotor yoke. When the rotor yoke with a floppy disc placed thereon is rotated, the drive pin is interposed between a front edge defining the hole formed in the center hub and a side defining the guide path, and pushed towards an outer edge defining the hole.

摘要： A motor provided with a rotational-speed detector has a driving coil for driving the motor, a driving magnetized portion, a rotational-speed detecting magnetized portion, and a detecting pattern. An even number of blocks of the detecting patterns having detecting lines are provided. A pair of blocks are displaced from each other in the rotating direction in relation to the arrangement of the N poles and the S poles of the rotational-speed detecting magnetized portion by an amount equal to one pitch between the detecting lines. An adder for adding currents flowing in the detecting lines of the respective blocks is provided. Alternatively, a subtracter for calculating a difference between currents flowing in the above-mentioned detecting lines is provided. Due to magnetic flux from the driving coil, noise currents are generated in the connecting lines for connecting the detecting line. However, noise currents IA and IB generated in the respective blocks A and B cancel each other. Absolute values of rotational-speed detecting signals Ia and Ib are added. Accordingly, an adverse influence of the magnetic flux generated from the driving coil is eliminated, thereby stabilizing the level of the rotational-speed detection output. The rotational speed of the motor is thus controlled with high precision.
摘要翻译：设置有转速检测器的电动机具有用于驱动电动机的驱动线圈，驱动磁化部分，转速检测磁化部分和检测图案。提供具有检测线的检测图案的偶数个块。相对于旋转速度检测磁化部的N极和S极的配置，一对块相对于检测线之间的一个间距的量相对于旋转方向彼此偏移。提供一种加法器，用于增加在各个块的检测线中流动的电流。或者，提供用于计算在上述检测线中流动的电流之间的差的减法器。由于来自驱动线圈的磁通，在用于连接检测线的连接线中产生噪声电流。然而，在各块A和B中产生的噪声电流IA和IB相互抵消。加上旋转速度检测信号Ia和Ib的绝对值。因此，消除了从驱动线圈产生的磁通的不良影响，从而稳定了转速检测输出的水平。因此，以高精度控制电动机的转速。
