モータ制御システム
Document Type and Number:
Japanese Patent JP7367373
Kind Code:
B2
Abstract:
The motor control system is mounted on a movable object 1. A control unit 21 is provided to control a drive motor 3 such that a requested amount of rotary power of the drive motor 3, which is set on the basis of a detection value of an output sensor 54, is output within a specified output range. A magnetization control section 21b of the control unit 21 changes a magnetic force of a magnetic force variable magnet 35 installed in a rotor 33 of the drive motor 3 such that the magnetic force of the magnetic force variable magnet 35 substantially matches an electromagnetic force generated in a coil 36. A base magnetic force that serves as a reference of the magnetic force variable magnet 35 is set to a magnetic force that substantially matches the electromagnetic force generated in an upper limit load region.
