Variable frequency motor stator core structure

The utility model discloses a variable frequency motor stator core structure, including the number of stator laminated together constitute a stator iron core lamination, and from inside to outside ends of the stator iron core end plates, pressure ring ; annular shape of the stator core and the inner hole in the circumferential direction with a plurality of radial grooves, and said end plate at its inner annular circular holes circumferentially provided with a plurality of said stator core radial grooves within the core hole radial grooves corresponding to the position of said pressure ring annular shape, the stator core and the outer circumferential surface of the end plate has a plurality of axial direction of the stator core extending along a concave grooves, each groove respectively embedded in a rod, both ends of each of said rod fixedly connected with said pressure ring. The invention does not change the size of the motor mounted in the case, by changing the length of the stator iron core, to achieve a m
