Hybrid power automobile start-up energy production integrated electric motor temperature field measuring systems

Abstract

The invention discloses a stator and rotor temperature field measurement system of a starting and generating integrated motor used for a hybrid vehicle. Patch-typed stator temperature sensors are arranged in different winding coil clearances of an ISG motor stator; signal output leads of the patch-typed stator temperature sensors are connected with an A / D converter by which the patch-typed statortemperature sensors are connected with a computer; patch-typed rotor temperature sensors are arranged in magnetic steel sheets of the ISG motor rotor, with signal output wires connected with signal output contacts of the external edge of the motor rotor; the signal is input into the A / D converter by a measurement probe and is then transmitted into the computer. The temperature increment curve of the stator winding and rotor magnetic steel sheets can be output by an ISG motor temperature field test when the ISG motor outputs fixed power; meanwhile, the temperature distribution of the ISG motorcan be measured under the output states of various rotation speeds and various powers.

Description

Hybrid Electric Vehicle Starter Generator Integrated Motor Temperature Field Measurement System technical field The invention relates to a motor temperature field detection test device, in particular to a temperature field measurement device for an integrated starter generator motor (Integrated Starter Generator in English, ISG motor for short) used in a hybrid vehicle. Background technique Vehicle hybrid is a new type of vehicle energy saving and environmental protection technology. The ISG motor is an important part of it. During the operation of the vehicle, the ISG motor absorbs the braking energy and the surplus energy of the engine and stores it. When high power output is required, the ISG motor assists the output, and the power output will not increase emissions, thereby achieving The purpose of energy saving and environmental protection. The temperature field of the winding coil and rotor magnetic steel sheet of the ISG motor changes with the different working con...

AI Technical Summary

Problems solved by technology

The temperature field of the winding coil and the rotor magnetic steel sheet of the ISG motor changes with the different working conditions of the motor. If the motor temperature is too high, the performance of the motor will decrease, and even the insulation of the coil will fail, and the magnetic steel sheet will be demagnetized, etc., thus causing safety accidents. Therefore, it is necessary to measure and analyze the temperature field of the motor

At present, there is no relevant measuring equipment for the temperature field of the ISG motor in the working state in China.
