<p>PROBLEM TO BE SOLVED: To effectively protect a connection part stored in a coil end from an impulse when magnetized by built-in magnetization.SOLUTION: A motor 1 including coil groups 42U, 42V and 42W concentrically arranged and Y-connected is magnetized in the state that a rotor 3 is incorporated in a stator 4. Each coil C of the coil groups 42U, 42V and 42W having each phase is formed by a distributed winding and is set so that a repulsive force effect section RS having a reverse direction is longer than an attractive force effect section AS having the same direction when the direction of magnetization current flowing through each of coil ends 43u and 43v having an external phase and an intermediate phase is viewed from a rotary shaft A. The connection part 50 of a wire W is stored to avoid the attractive force effect section AS.</p> |
