Abstract

Due to current displacement effects, AC copper losses are part of the main loss components in electrical machines. In traction drive applications, it is necessary to know as precisely as possible the machine losses for all operating points. They serve as input variable for determining the efficiencyoptimal map, which is the basis of how the machine is supplied with current. In this paper, a novel AC copper loss calculation approach for calculating the AC copper losses for determining the efficiency-optimal map is presented, which considers the inner phase angle in addition to the dependence on speed. Furthermore, the influence of the circulating current in deltaconnected windings on the AC copper losses is analyzed and the losses are compared with those in y-connection in order to evaluate the use of the delta connection in traction applications.
