Motor drive system

A motor drive system, comprising:

• a first motor drive control device to supply first power to first coils of a coil group consisting of a plurality of coils arranged successively;
• and
• a second motor drive control device to supply second power to second coils of the coil group that are adjacent to the first coils,
• wherein the first motor drive control device comprises:
• a movement information communication unit to acquire a movement detection value representing a movement position or a movement speed of a mover moving along the first coils;
• a position and speed control unit to generate a thrust command to the mover that is a command to cause the movement detection value to follow a movement target value that is a time-series movement target value received from an external device;
• and
• a current control unit to supply, to the first coils, the first power to cause thrust generated on the mover to follow the thrust command, and generate data on third power to be supplied to the second coils and transmit the data on the third power to the second motor drive control device when the mover moves from the first coil to the second coil, and
• the second motor drive control device supplies the second power calculated using the data on the third power to the second coils.
