20140165525 | MOTOR DRIVE DEVICE AND ELECTRIC MOWING MACHINE - A motor drive device according to one aspect of the present invention includes an operation switch, a control unit, an adjusting unit, and a normal/reverse changeover switch. The control unit is configured, in a case where the operation switch is in an on state, to control a current flowing to the motor based on a control target value adjusted by the adjusting unit when a rotational direction of a motor is set to a normal direction by the normal/reverse changeover switch; and to control the current flowing to the motor based on a preset fixed reverse rotation control target value used to reversely rotate the motor, regardless of the control target value set by the adjusting unit, when the rotational direction is set to a reverse direction by the normal/reverse changeover switch. | 06-19-2014 |

20100067140 | Disk-Drive Read/Write Head Retraction Velocity Control - One embodiment of the invention includes a voice coil motor (VCM) drive system. The system includes a VCM configured to move a read/write head across a magnetic disk in response to a current flow through the VCM. The system also includes a VCM output stage configured to direct the current through the VCM in one of a first direction corresponding to retraction of the read/write head and a second direction corresponding to extension of the read/write head in response to switching control signals. The system further includes a retract controller configured to control a retraction velocity of the read/write head by generating the switching control signals to provide the current in the first direction to increase the retraction velocity of the read/write head and to provide the current in the second direction to decrease the retraction velocity of the read/write head during a retraction mode of the VCM drive system. | 03-18-2010 |
20100302670 | DISK DRIVE - To provide a disk drive capable of inhibiting the occurrence of acoustic noise caused by a voltage pulse when the head is retracted using a speed control method using voltage obtained by rectifying a back electromotive force after the power source has been cut off from the rotation of a spindle motor. Retraction control circuit is used to control the on and off modes of transistors in accordance with the speed of VCM. The voltage across VCM becomes a voltage that can be regulated with VCM voltage control circuit. At this time, voltage is supplied to the terminals based on the voltage of ISO5V that is the rectified voltage of the back electromotive force of the spindle motor and the pulsating voltage is synchronized and produced at both terminals. As a result, the potential difference across VCM is such that the pulsating voltage is negated and acoustic noise is inhibited. | 12-02-2010 |
20100315738 | MOTOR CONTROL DEVICE AND DISK DRIVE DEVICE - The objective of this invention is to provide a motor control device, and a disk drive device using the same, in which during emergency operation it is possible to supply necessary power to the motor while limiting enlargement of the circuit area. During the retraction operation, control is performed to alternate between a short-circuit mode in which each terminal U, V, W of the spindle motor Ml is short-circuited to the terminal ICOM, and a rectifying mode in which the back electromotive force of the spindle motor M | 12-16-2010 |
