Design of small, high-voltage auxiliary motors for application on externally-powered transit vehicles is difficult because of the environment in which they operate. They may be subjected to extremes of temperature, humidity, dirt and other contaminants, shock and vibration, and other arduous circumstances. The electrical design of a small, high-voltage motor is always a challenge because of space constraints; additionally, the line voltage on externally-powered vehicles is subject to wide steady-state variation as well as severe transients. Some recent design improvements made to address these difficulties are discussed. It is seen that the design of small high-voltage auxiliary motors offers unique challenges. The solutions developed for traction motors can be used in some cases, usually in modified form. In other cases, new solutions have been developed and implemented. An implicit part of the challenge is providing what it takes to make a successful motor at a price the market will support.
