PROBLEM TO BE SOLVED: To prevent a motor shaft from being enlarged.SOLUTION: In a motor unit, a motor 12 including a motor shaft 11, an operation control board 70 which executes control for rotationally operating the motor 12 and an arithmetic control board 80 are made into unit. On the operation control board 70, mounting spaces 70a and 70b are formed for mounting control electronic components required for controlling the rotational operation of the motor 12. On the operation control board 70, the mounting spaces 70a and 70b for the control electronic components are provided in a shaft length direction of the motor shaft 11 in such a manner that the control electronic components can be disposed in the shaft length direction of the motor shaft 11. On the arithmetic control board 80, mounting spaces 80a and 80b for mounting control electronic components required for calculating a rotation angle of the motor 12 are provided in a shaft diameter direction of the motor shaft 11.SELECTED DRAWING: Figure 1 |
