9 Prototype of a high speed claw pole motor B. High speed claw pole motor In our previous work, a high speed claw pole motor as shown in Fig. 9 with an SMC stator core was developed [3, 8, 9]. 4, and the structure (one pole pitch of one stack) is shown in Fig. 10. 11 illustrates the topology of one of the three stacks. The stator consists of the claw poles, the yoke, and the phase winding. The rotor is simply made of a ring PM magnetized in four poles and mounted on the rotor core. The three stator stacks are shifted for 120o (electrical) apart from each other.

Generally, there are two kinds of analysis models for thermal analysis in electrical machines, namely the thermal network model and the FEM [14, 15, 20, 25]. The following sections will present examples for the two methods. 2 Thermal Network Model Two design examples will be illustrated to show the usage of thermal network model for the thermal analysis of PM-SMC motors. The ﬁrst one is a TFM, and the second is a high speed claw pole motor. A. Transverse flux machine In this study, the temperature rise was calculated by using a hybrid thermal network model with distributed heat sources, as shown in Fig.
