Title:
ツイン駆動装置及びモータ制御方法
Document Type and Number:
Japanese Patent JP7188214
Kind Code:
B2
Abstract:
To prevent a stepping motor from getting out of step by appropriately adjusting an assisting amount of a brushless motor according to twin-driving of the stepping motor and the brushless motor.SOLUTION: A twin-driving apparatus comprises a stepping motor, a brushless motor, a drive mechanism for rotationally moving the same load using the stepping motor and the brushless motor, and a control part for controlling operations of the stepping motor and the brushless motor. A rotation axis in the brushless motor or a rotation axis in the drive mechanism is provided with an encoder. The control part calculates an angle deviation amount of the stepping motor by comparing a pulse signal that drives the stepping motor with a pulse signal output from the encoder to increase/decrease an output of the brushless motor according to the angle deviation amount.SELECTED DRAWING: Figure 4
