Electric motor and pump mounting bracket assembly and method of making

摘要

An electric motor and pump mounting bracket assembly comprising an electric motor and a bracket fastened to the motor for supporting a pump which is driven by the shaft of the electric motor. The electric motor comprises a cylindrical shell which encircles the stator of the motor and a pair of end members engage surfaces on the shell which are accurately positioned longitudinally of the shell relative to one another and relative to the axis of the shell. The end members rotatably support a shaft in concentric relation to the shell. The pump mounting bracket includes a planar surface that is accurately located parallel to and a predetermined accurate distance from the centerline of the shell to form the mounting surface for the pump. The bracket further includes an opening through which the connecting link to the shaft of the motor extends. The accurate surfaces on shell are in predetermined longitudinally spaced relation to the centerline of the opening in the bracket. The assembly further includes an external rotating fan that includes blades which circulate air through the motor for cooling the motor.
