Abstract: A method is provided of securing a stator in an electrical machine which includes a casing, a rotor mounted within the casing and a stator which is axially slidable with respect to the casing. The method comprises the steps of wedging the stator in position by means of co-operating annular chamfer surfaces formed in mounting rings located at each end of the stator which co-operate with opposed chamfer surfaces formed on a plurality of mounting bars and a hollow cylindrical sleeve both of which form part of the casing. When the casing and stator assembly is pressed together, such as when the end plates of the motor are secured to the casing, the stator is wedged in position between the chamfer surfaces. The method can be utilized for reconditioning existing motors.

Abstract: An electrical motor has a casing 62 and a removable end plate 68. When the end plate 68 is removed the stator 50 can slide out of the casing 62 for servicing or repair without disturbing the rest of the motor in any way. Annular hampered mating surfaces insure accurate centering.
