Abstract (en)
[origin: WO2020083553A1] The invention relates to a temperature monitoring and protective circuit (1) for monitoring a specified motor limit temperature TG formed from a tooth (2), particularly a tooth (2) of a laminated core of a motor, comprising a detection device (5) for detecting a magnetic flux in the tooth, the tooth (2) having a cavity (3) in which a ferromagnetic material (4) has been introduced, the Curie temperature TC of which is below or close to the limit temperature for the motor or a motor temperature to be monitored.
