- The paper presents the thermal equivalent diagram method for define of stator and squirrel cage windings resistance thermal increases of the induction motor. In article discussed assumption form construction thermal equivalent diagram. Them monitoring of heating of induction motor is presented for example two motors, on power 3 [kW] and 18,5 [kW]. Presents verification measurements increase temperatures in 3 kW induction motor on measurements station and 18,5 [kW] on base date received from producer of induction motor. In next part of paper was reduction structure of thermal equivalent diagram. Reduction depended to change structure of diagram (e.g. to omit flow of heat between some part of motor) and power loss (e.g. bearing friction and cooling loses). For diagrams, who was construct in effect simplification assumption, effect of computer simulation is presented. Precision of computer simulations was compare with basing thermal equivalent diagram - verifying in laboratory measurements. Courses of stator and rotor windings temperature and rear bearing are presented. In the end of paper author presents conclusion from computer simulation and laboratory measurements, who was application this method in practical application.
