Title:
CONTROL DEVICE FOR DRIVE DEVICE, AND DRIVE SYSTEM
Document Type and Number:
Japanese Patent JP2022175025
Kind Code:
A
Abstract:
To provide a control device for a drive device, and a drive system, capable of achieving a structure with a small number of rotation sensors for use in a non-contact drive transmission unit.SOLUTION: In a control device 30, a phase detection unit 32 detects a phase shift amount of a driven-side rotating member 25 relative to a driving-side rotating member 23, both members constituting a drive transmission unit 22 and magnetically coupled to each other, on the basis of a load current Im of a motor unit 21 detected by a current detection unit 31. The control device 30 sets a target position of the driving-side rotating member 23 so as to include an advancing-side correction based on the phase shift amount, and controls the drive of the motor unit 21 on the basis thereof.SELECTED DRAWING: Figure 1
