This report documents the successful development and evaluation of a system designed to reduce the failure rate of self-ventilated traction motors used in cold climate cities. Forced ventilation with clean, dry air appeared to provide a suitable solution. Tests were conducted on filters and separators that could eliminate the contaminants and provide the clean dry air. All devices proved unsatisfactory. A low velocity inlet separator was developed in the laboratory where it proved highly successful in separating snow and freezing mist. This new system was then committed to prototype design for installation on two rapid transit cars of the Chicago Transit Authority. These cars have been operated through 1983 with a high degree of success. Cost benefit analysis of the system indicated that it could be economically incorporated into a transit system's self-ventilated traction motor propelled cars.
