摘要：
The stator (1) has a ferromagnetic stator core (2) wound with stator windings (4), and a control electronic assembly (6) for controlling the stator windings. The stator core together with the stator windings are enclosed in a molded encapsulation (10) made of plastic material with defined thermal conductivity (lambdast). A temperature sensor (12) is arranged on an outer side of the encapsulation. The electronic assembly calculates temperature in a region of the windings based on stator temperature detected by the sensor by considering a specific stator temperature profile stored in a memory. The temperature sensor is provided as a surface-mounted device-component.
