- Method of direct cooling of winding bar utilizing liquid medium contacting with side surface along whole bar length is described in the paper. Main advantage of that cooling method is avoiding necessity of increasing length of passive parts of bar and therefore decreasing losses in the winding. Besides that cooling method enables effective regulation of cooling intensity by changing medium speed in cooling duct. The method for calculation of thermal distribution along length of bar for given dimension of bar and cooling duct, current density and medium speed is presented. Also the solution of reverse problem in, which for known bar and duct dimension, current density and given maximum value of temperature, the medium speed in canal is calculated. The calculations results of maximum value of bar temperature for different length, current density and medium speed are presented. Also dependence of medium speed on bar length and current density for known maximum value of bar temperature is discussed.
