Title:
MOTOR DRIVING DEVICE, FIXATION DEVICE AND IMAGE FORMATION APPARATUS
Document Type and Number:
Japanese Patent JP2020024272
Kind Code:
A
Abstract:
To achieve the smooth operation while avoiding cost increase and mechanical restrictions due to the use of an encoder when driving a common load with a plurality of motors, and efficiently drive the load by balancing the plurality of motors.SOLUTION: A motor driving device 10 includes: a closed-loop type drive control unit (DSC11) for performing the closed-loop control of one motor on the basis of a rotation detection signal (FG) of one motor 1; an opened-loop type drive control unit (pulse generator 12) which inputs the drive power (stationary PWM) to another motor 2; and a central control unit (control CPU 13). The central control unit executes the closed-loop control by inputting a target value to the closed-loop type drive control unit, and sets a setting value of the driving power of the opened-loop type drive control unit on the basis of the actual time information (for example, an average value of immediately preceding 500 ms) of the driving power value in the closed-loop type drive control unit at that time. The opened-loop type drive control unit executes the opened-loop control in accordance with the input setting value.SELECTED DRAWING: Figure 1
