NTC temperature sensor for electric vehicle motors.Moving object detection module

　　With the rapid development of modern electric vehicle technology, the output power demand of electric vehicles is gradually increasing, and the working current of the motor is constantly increasing, resulting in a continuous increase in the temperature of the motor stator winding. The motor needs to have an NTC temperature sensor built-in to monitor the stator winding temperature in real-time. When the temperature exceeds the set protection threshold, the motor controller needs to take corresponding measures to prevent the stator winding from overheating and causing damage to the insulation paint.

　　The NTC temperature sensor used for motor winding uses a single ended glass sealed thermistor combined with a double-layer Teflon sleeve, making the glass sealed NTC thermistor more waterproof. After the double layer Teflon sleeve and Teflon insulated lead are fused at 450 ℃, the insulation layer of the lead is completely fused with the Teflon, making it highly waterproof and oil resistant; It can completely immerse the product in water or oil for normal operation, and can work normally in high-temperature environments above 250 ℃ for a long time, with a long service life and strong practicality. And the head size is small. Small size, small installation space requirement. This high waterproof and oil resistant NTC temperature sensor is more suitable for use in automotive motors.
