Electric motor used as drive element of motor vehicle, has stable tube-like structure comprising access region that is provided with opening for insertion and removal of temperature sensor

摘要

The electric motor (10) comprises a rotor (12) and a stator (20). The stator comprises several windings forming a coil head (22), such that each winding of electric motor is composed of several coils. A stable tube-like structure (26) is arranged in region of the coil head, and is provided with a heat transfer region (30) and an access portion (32). The heat transfer region of stable tube-like structure is fixedly connected with coil. The access region is provided with an opening (36) for insertion and removal of a temperature sensor.
