The widespread adoption of electric vehicles has brought about many new technological challenges, one of which is the temperature monitoring of electric motor windings. To ensure proper operation and longevity of the motor, accurate temperature measurement and monitoring are crucial. High temperatures can lead to motor damage, posing risks to new energy vehicles and endangering users.
To prevent motor damage due to excessive temperatures, temperature-sensitive electronic components known as NTC thermistors are used for motor winding temperature measurement. By employing NTC thermistors, the temperature of the motor winding can be monitored in real time, enabling timely protective measures to be taken for the motor.
An NTC thermistor is an electronic component sensitive to temperature changes. It is made from a negative temperature coefficient thermosensitive material, and its resistance decreases as the temperature rises. This characteristic makes it an ideal choice for temperature measurement.
In motor windings, an NTC thermistor is connected to the winding. When the motor operates, the temperature of the winding affects the resistance value of the NTC thermistor. By measuring the resistance value of the NTC thermistor, we can determine the temperature of the motor winding.
Why choose NTC thermistors for temperature measurement in electric vehicle motor windings? This is because NTC thermistors offer several advantages that are suitable for motor winding temperature measurement:
High Accuracy: NTC thermistors are highly sensitive to temperature, providing precise temperature measurement results.
Short Response Time: NTC thermistors have a fast response speed, enabling real-time monitoring of temperature changes.
Cost-Effective: Compared to other temperature sensors, NTC thermistors are more cost-effective.
