PROBLEM TO BE SOLVED: To provide an electrical driver with high vibration resistance and heat resistance capable of improving the detection accuracy of rotation angle by reducing deflection of a shaft.SOLUTION: The electrical driver includes: a resolver rotor as a part to be detected by a rotation angle sensor on the end part of a motor shaft 7; and a resolver stator iron core 502 and a coil as a detection unit of the rotation angle sensor at a coaxial position as the rotation axis of the shaft. The resolver stator iron core 502 is attached to the heat sink 16 of a control section and the heat sink 16 and the control board 17 of the control section are disposed along a plane perpendicular to the rotation axis of the shaft 7. |
