  • Insulator set and stator used for generator and electric motor, and method for manufacturing stator
    Patent number: 11632010
    Abstract: A stator is improved in work efficiency of mounting to a stator core is provided. The stator includes insulators sandwiching the stator core therebetween. The stator core includes a plurality of teeth that radially projects. Each of the insulators includes a plurality of tooth covering portions that radially projects. The tooth covering portions cover the teeth. In a facing portion of one of the insulators facing the stator core, a peripheral portion projects more than a center portion. In a facing portion of the other of the insulators facing the stator core, a center portion projects more than a peripheral portion.
