Title:
位相調整装置および位相調整方法
Document Type and Number:
Japanese Patent JP7364541
Kind Code:
B2
Abstract:
To provide a phase adjusting device capable of aligning initial phases of two drive shafts that are synchronously controlled with a simple configuration.SOLUTION: A phase adjusting device 70 comprises: a torque acquisition unit 82 acquiring a torque; a position acquisition unit 80 acquiring a rotational position of a first motor 26; a first motor control unit 84a that rotates the first motor 26 in a first rotational direction until the torque exceeds a threshold, and then that rotates the first motor 26 in a second rotational direction until the torque exceeds the threshold again; a storage control unit 86 that stores, in a storage unit 90, a rotational position as a first rotational position when the first motor 26 is rotated in the first rotational direction and the torque exceeds the threshold and that stores, in a storage unit 90, a rotational position as a second rotational position when the first motor 26 is rotated in the second rotational direction and the torque exceeds the threshold again; a phase position calculator 88 calculating a third rotational position, based on the first rotational position and second rotational position; and a second motor control unit 84b rotating the first motor 26 to the third rotational position.SELECTED DRAWING: Figure 2
