Title:
MOTOR DRIVE DEVICE AND MOTOR DRIVE METHOD
Document Type and Number:
WIPO Patent Application WO/2024/090135
Kind Code:
A1
Abstract:
A motor drive device (1) comprises: a target speed generation unit (10) that generates a target speed signal (St) indicating a target speed of a motor (2); an actual speed detection unit (14) that generates an actual speed signal (Sr) indicating the actual speed; and a drive unit (30) that drives the motor (2) so that the actual speed indicated by the actual speed signal (Sr) approaches the target speed indicated by the target speed signal (St). The target speed generation unit (10) generates an input speed signal (Si) based on an input instruction and a provisional speed signal that is higher than the actual speed signal (Sr) at the time of startup, and, when the actual speed indicated by the actual speed signal (Sr) at startup is higher than the speed indicated by the input speed signal (Si), outputs the provisional speed signal as the target speed signal (St).
