In the field of electrical machines, there is a trend towards increasing the speed in order to improve the power density especially for electric vehicles. Efficiency of the drive train plays an important role because it has a direct impact on the range of the vehicle. For this reason, it is particularly important not only to keep the weight of the drive low, but also to increase the efficiency as much as possible. This makes it even more important to be able to precisely calculate and minimize the losses when designing the motor. In addition to classical loss terms such as iron and copper losses, it is important to consider additional losses such as proximity and skin effect losses in the winding and eddy current losses in the magnets as well as losses in stranded wires.This paper describes efficient and fast methods for calculating additional losses in the winding of permanent magnet synchronous machines. Instead of a full transient 3D finite element analysis (FEA) a hybrid method is presented, which combines the results of a 2D magnetostatic FEA with an analytical method for calculating ac losses in the winding efficiently.
