ABSTRACT:
A stator for a fractional horsepower motor has a mounting hole of reduced dimensions for fixing the position of motor mounting brackets which support a rotor. The configuration of the mounting holes increase the area where magnetic flux may pass. One configuration reduces the depth of the mounting hole to one or two laminates of each side of the stator. Another configuration is an elongated hole which lies in the direction of the magnetic flux. Each laminate may have a tang which interlocks with tangs on other laminates when the laminated stack is squeezed together in a punch press.
