Document Type and Number:
WIPO Patent Application WO/2020/226156
Kind Code:
A1
Abstract:
The present invention provides a motor control device (40) for controlling the driving of a motor (10) having a coil (11), the motor control device (40) being provided with a drive circuit (41) and a control unit (50). The drive circuit (41) has a plurality of switching elements (411-416), and switches the energization of the coil (11). The control unit (50) has an energization control unit (65) and a current limiting unit (62). The energization control unit (65) controls the energization of the coil (11) so that the motor (10) is accelerated, then decelerated, and the rotation position of the motor (10) stops at a target rotation position. The current limiting unit (62) limits the current during deceleration control.
