Abstract
A sealed electric motor assembly suitable for use in a hostile environment, such as high temperatures, high pressures or in atmospheres containing toxic or corrosive gases. The motor assembly is especially adapted for use with a blower assembly. The stator windings are protected from the hostile environment by hermetically sealing them between the cylindrical housing for the motor and a thin metal canister secured tightly against the inner wall of the housing. Also disclosed are arrangements for removing heat from the motor during its operation. Service life of the electric motor of this invention is greatly increased as compared to conventional motors when operated in a hostile environment.
