Title:
IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2021158785
Kind Code:
A
Abstract:
To solve the problem in which: a clockwise torque T1 is generated in a rotor of a first motor, and a counterclockwise torque T2 is generated in a rotor of a second motor; a counterclockwise torque T1 and a clockwise torque T2 are applied to a load; as a result of this, the efficiency of driving the load is reduced.SOLUTION: A first motor 402a is controlled based on a command phase θa_ref, and a second motor 402b is controlled based on a command phase θb_ref(=θa_ref+θ_dif). As a result of this, a reduction in the efficiency of driving a load with the first motor 402a and the second motor 402b can be prevented.SELECTED DRAWING: Figure 7
