A motor includes a round steel frame with a stator unit fixedly mounted therein and spaced from the frame ends. Spaced bearing frames are secured within the round frame and support a rotor unit within the stator unit and in the bearing frames. One or both bearing frames are spaced from the round frame ends, and define corresponding auxiliary compartments. In a motor pump unit, an end plate closes one end and defines a control compartment. The pump housing closes the opposite end and forms a fan and drip compartment within the round frame. The round frame has openings in the drip compartment to by-pass pump water leakage from the motor compartment. A fan in the fan compartment provides motor cooling. Motor controls such as power connectors, a centrifugal start switch unit, electronic timers, and the like are mounted within the control compartment to form a self-contained motor. The motor compartment and various auxiliary compartments can be formed within the frame by appropriate securing of the bearing frames and internal walls in the round frame. Thus, two and three compartment motors are formed with one or more internal wall structures secured directly to the round tubular motor frame.
