Abstract:
A motor drive system includes motor drive control devices supplying first and second powers to first and second coils, respectively. The first motor drive control device includes: a detector communication unit acquiring a mover movement detection value; a position and speed control unit generating a thrust command to cause the movement detection value to follow a time-series movement target value received from an external device; and a current control unit supplying, to the first coils, the first power to cause thrust generated on the mover to follow the thrust command, and generating data on third power to be supplied to the second coils and transmitting the data to the second motor drive control device when the mover moves from the first coil to the second coil. The second motor drive control device supplies the second power calculated using the data on the third power to the second coils.
