FIELD: electrical engineering; intermittently running motors for agriculture, food, refining, and other industries. SUBSTANCE: motor has primary temperature transducers, disconnecting switch, and magnetic starter, as well as heating elements; novelty is that primary transducers and heating elements are mounted on inner side of motor fan casing. Such arrangement ensures fast response in case of rotor seizure and provides for in-service installation of protective gear without removing motor from driven mechanism. EFFECT: improved reliability of motor and protective gear especially during intermittent running. 2 cl, 2 dwg
