Influence of winding and shaft cooling on the thermal characteristics of a traction machine for heavy-duty distribution transport

: This paper studies the inﬂuence of diﬀerent cooling technologies on the power density of a traction machine for heavy-duty distribution transport. A prototype induction machine is built with a housing cooling jacket, potted end-windings, entire winding cooling, andshaftcooling.Electromagneticﬁniteelementandthermallumped-parametermodelsare parameterized and veriﬁed using test bench measurements. The inﬂuence of each thermal resistance along the heat paths is studied and discussed. The results are used for studying diﬀerent cooling technologies. The results indicate an improvement of the continuous power density up to 108% using shaft cooling and up to 15.6% using entire winding cooling.
