Abstract:
A motor/generator comprising,a stator having a plurality of cores separated from each other and arranged on a circle, each of the cores comprising a base which increases a width in a direction away from a center of the stator; a rotor rotating on an inner side of the stator, the rotor having a rotation axis; a plurality of retaining plates in a band shape each of which is disposed in parallel with the rotation axis and penetrates a space formed between the bases of adjacent cores in a direction of the rotation axis, both ends of each retaining plate protruding from the space, the retaining plates supporting the bases of the cores so as to prevent a displacement of the cores in the direction towards the center of the stator; a case which prevents a displacement of the cores in the direction away from the center of the stator; and a pair of ring-shaped fixing members disposed on the outer side of the stator in the direction of the rotation axis so as to face each other and respectively holding the ends of the retaining plates protruding from the space in the direction of the rotation axis.
