<p>A high-output induction motor having its stator and rotor elongated without affecting grinding and die-casting while maintaining the flexural rigidity of the articles. The induction motor (10) includes two rotor cores (14) fixed to a spindle with a predetermined gap in an axial direction and two stator cores (24) encompassing the rotor cores (14) and fixed to a sleeve portion (22) of housing means (20). Each rotor core (14) includes a plurality of secondary conductors (36) extending in the axial direction and a pair of end rings (38) connecting each secondary conductor (36) at both ends of the rotor core (14) in the axial direction. Each stator core (24) includes a plurality of windings (26). These rotor cores (14) and stator cores (24) are shaped longer to such an extent that die-casting and grinding are not affected and the flexural rigidity of the articles is maintained.</p> |
