Title:
MOTOR DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/249245
Kind Code:
A1
Abstract:
This motor drive system (101) comprises a motor drive control device (1A) for supplying a first power to coils (2A) and another motor drive control device (1B) for supplying a second power to coils (2B). The motor drive control device (1A) has: a detector communication unit (14A) that obtains an operation detection value indicating the operation position or the operation speed of a mover (3); a position/speed control unit (10A) that generates a thrust command that is a command for causing the operation detection value to follow a time-series operation target value received from an external device (20); and a current control unit (11A) that supplies, to the coils (2A), the first power for causing the thrust generated in the mover (3) to follow the thrust command and generates the data of a third power supplied to the coils (2B) to transmit the data to the motor drive control device (1B) when the mover (3) moves from the coils (2A) to the coils (2B). The motor drive control device (1B) uses the data of the third power to supply the calculated second power to the coils (2B).
