Document Type and Number:
Japanese Patent JP2019146454
Kind Code:
A
Abstract:
To provide a technique by which the presence of a motor whose rotation speed is improper can be detected even if information about rotation speeds of motors outputted from a device equipped with a plurality of motors.SOLUTION: A motor device 1 having a plurality of motors 10a and 10b comprises: a plurality of detection parts 11, provided in the motors respectively, which detect rotation speeds of the motors; and an output control part 12 that outputs single output rotation speed ORS on the basis of the rotation speeds of the motors inputted from the detection parts. The output control part calculates a conversion value by multiplying at least one inputted rotation speed of the motor by a coefficient derived based on a target rotation speed of the motors and determines the output rotation speed.SELECTED DRAWING: Figure 1
