- The paper presents a thermal model of two-speed induction motors with water-cooled frames. This model is made basing on the method of finite differences with the use of interpretation of the heat conduction equations in the form of thermal-electrical networks. It enables calculating temperature distributions in all constructional elements of induction motor and in the stream of water flowing in the frame as well as in the streams of air flowing in ventilation ducts of the rotor core and the frame. Basing on the model, a computer program that can be used for computer aided design is developed. Exemplary thermal calculations are carried out for the two-speed induction motor of 85/250 kW. The results obtained from simulations are compared with those from thermal measurements.
