System for measuring temperature field of startup and electrification integrated motor

The present utility model discloses a starting and power-generating integrated motor stator and a rotor temperature field measuring system for a hybrid electric vehicle. A patch type stator temperature sensor is provided in a gapping place of different winding coils of an ISG motor stator, a signal output guiding wire is connected with an A/D converter and is connected with a computer through the A/D converter; the patch type stator temperature sensor is provides in the magnetic steel sheet of the ISG motor stator, a signal output wire is connected with a signal output contact of the outer edge of the motor rotator, signals are input into the A/D converter through a measuring probe and are then transmitted into a computer. Through the measuring of the ISG motor temperature field, a temperature rise curve of stator windings and the magnetic steel sheet of a rotor can be obtained when the ISG motor outputs at a constant power, at the same time, temperature distribution of the ISG motor at any rotating speed or various power output states can also be measured.
