A motor, in particular an electric motor, possesses a motor housing (2) in which a motor-filling medium (6) surrounding the motor (11) is situated, and a pressure housing (1) which surrounds the motor housing (2) and in which a housing-filling medium (5) is situated. To be able to carry away adequately the lost heat produced, a heat exchanger (3), through which a cooling medium flows, is arranged on the inner wall (1) of the pressure housing. The heat exchanger preferably consists of a cooling channel (3) which runs spirally over the length of the pressure housing (1). The motor-filling medium (6) preferably serves as a cooling medium for the heat exchanger (3).
