モータ駆動装置、モータ装置、および集積回路装置
Document Type and Number:
Japanese Patent JP5077348
Kind Code:
B2
Abstract:
A motor driving device (100) includes an inverter (20), a speed control unit (40), and a regeneration preventing means (50). The inverter (20) converts supplied DC power to driving power for driving a motor (10), and supplies the driving power to the motor (10). The speed control unit (40) generates a speed control signal group based on a speed command signal Sref and a speed detection signal N, and adjusts the driving power based on a drive control signal VSP1 included in the speed control signal group, thereby controlling the speed of the motor (10). The regeneration preventing means (50) determines whether the motor (10) is in a state possibly causing regenerative phenomena or in a state not causing regenerative phenomena based on the speed command information included in the speed command signal Sref and the speed detection information included in the speed detection signal N, and performs a regeneration reduction process to reduce regenerative phenomena according to the determination result, thereby preventing regenerative phenomena.
