MOTOR SUPPORT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To reduce the axial direction length of a motor support structure. SOLUTION: A motor 1 is composed of a stator 2 fixed to a housing 4, a rotary shaft supported rotatably by the housing 4 with bearings 8 and 9 and a rotor 3 which has arm parts 3c formed on the stator side outer circumference of the rotary shaft so as to extend in parallel with the rotary shaft and is formed integrally on the rotary shaft so as to face the stator 2. A revolution sensor 6 which detects the revolution of the motor 1 is provided on the arm part 3c and on the outer circumference side in the radial direction of the bearing 9.
