  • Patent number: 5859482
    Abstract: Liquid cooled electric motors including stator frames having cast in place cooling conduits are described. In an exemplary embodiment, the conduit is arranged in a generally helical configuration and the stator frame is cast around the conduit so that the conduit is embedded within, and integral with, the frame. Spacer, or stabilizer, bars are engaged to the conduit and provide support for the conduit and facilitate maintaining the desired spacing between lengths of conduit and between the conduit and the frame wall. The stator frame with the cast in place cooling conduit has the advantages of a liquid cooled motor yet is believed to be lower cost than known liquid cooled motors. The frame also is believed to be less susceptible to corrosion and liquid leaks as compared to known liquid cooled motors.
