STATOR FOR ROTARY MACHINE

摘要

PURPOSE:To increase efficiency of a stator coil by shortening the length of its circumference and at the same time to prevent a magnetic electrode core from being displaced when the magnetic electrode core and a yoke core are combined. CONSTITUTION:A magnetic electrode core 14 and a yoke core 15 are individually formed and combined through a divided surface 17 including irregular fitness. The outside surface of the combined part is forcedly fitted into a frame housing 3. Windings are arranged in the condition close to alignment by rotating the magnetic electrode core to shorten the length of its circumference. The positioning of the magnetic electrode core 14 against the yoke core 15 and the support of the magnetic electrode core 14 are performed in the fitting part of two places which are different in the fit-in direction. Since each fitting part can be formed into a simple phase, the press-in part becomes hard to deform and the position of the magnetic electrode core 14 becomes hard to displace.
