ACTUATOR CONTROLLER, MOTOR CONTROLLER, MOTOR, IMAGE FORMATION DEVICE AND ACTUATOR EXCHANGING METHOD

To generate revolving speed roughly the same as that of a first motor on a second motor after changing.SOLUTION: An actuator controller controls the driving of a second motor 400 instead of a first motor 300 using a first driving signal P1 capable of controlling the driving of the first motor 300. The actuator controller comprises a first controller 200 which outputs the first driving signal P1 and is capable of inputting rotary speed ω1 of the first motor 300 and can be connected with the first motor 300, and a second controller 100 which controls the driving of the second motor 400 based on motor current I2 and rotary speed ω2 corresponding the first driving signal P1 and torque of the second motor 400. The first motor 300 and the second motor 400 have different torque T and rotary speeds ω1, ω2 and are common in a load.SELECTED DRAWING: Figure 1 【課題】第１モータと略同一の回転速度を、交換後の第２モータに発生させる。【解決手段】第１モータ３００を駆動制御可能な第１駆動信号Ｐ１を用いて、第１モータ３００の代わりに第２モータ４００を駆動制御するアクチュエータ制御装置であって、第１駆動信号Ｐ１を出力し、第１モータ３００の回転速度ω１を入力可能とし、第１モータ３００に接続可能とする第１制御装置２００と、第１駆動信号Ｐ１と第２モータ４００のトルクに対応するモータ電流Ｉ２と回転速度ω２とに基づいて、第２モータ４００を駆動制御する第２制御装置１００とを備え、第１モータ３００と第２モータ４００とは、トルクＴと回転速度ω１，ω２が異なり、負荷が共通する。【選択図】図１
