<P>PROBLEM TO BE SOLVED: To provide a motor which is equipped with a resolver that can prevent the influence of electromagnetic noise from a motor to the resolver and also can improve the production efficiency. <P>SOLUTION: This motor, which includes a rotor shaft 24 threaded into a rotor part and a resolver 25 for detecting the rotational position of the rotor shaft, includes a bearing 27, which is arranged at the end on the resolver side in the rotor shaft, and a resolver guide 70, which is arranged outside in the axial direction of the rotor shaft in the bearing so as to position the resolver in the axial direction of the resolver rotor 25a. For the resolver guide, a collar 72, which is arranged between the bearing and the resolver rotor and is extended outward in the radial direction of the rotor shaft, is formed therein, and the outer diameter d1 of the resolver and the outer diameter d2 of the collar of the resolver guide are smaller than the diameter d3 of an opening 81 formed on the bearing support side of a motor case. <P>COPYRIGHT: (C)2010,JPO&INPIT |
