Behind the efficient operation of electric motors, temperature is a key factor determining their service life and performance. Whether in industrial equipment, new energy vehicles, or precision automation fields, motor overheating can lead to insulation failure, demagnetization of permanent magnets, or even motor burnout, resulting in irreversible damage. Therefore, real-time, precise temperature monitoring is the core technology for ensuring safe motor operation and extending service life.
Why must motors be temperature-monitored?
Insulation protection: The temperature rating of the winding enameled wire directly determines the service life of the motor. Overheating can cause insulation carbonization, interturn short circuits, and ultimately burn out the motor.
Permanent magnet protection:
High temperatures can cause irreversible demagnetization of permanent magnets, significantly reducing performance and efficiency.
Fault warning:
Abnormal temperature rises are often a sign of current overload or mechanical failure. Timely power disconnection can prevent catastrophic damage.
Main methods of motor temperature measurement
Contact Temperature Measurement:
①KTY Series: Narrow effective measurement range, poor circuit compatibility, and relatively large size with higher error margins
②NTC Series: Wide temperature measurement range (probe -50°C to 300°C), with accuracy up to ±0.1°C, and lower cost
③Platinum Resistance Series: -70°C to 500°C (covering most motor applications), high stability, and significantly better shock resistance than glass-encapsulated products
Non-contact temperature measurement
① Infrared temperature measurement
② AI algorithm-based temperature calculation
Combining infrared temperature measurement with temperature measurement wires
Main issues encountered in motor temperature measurement
Accuracy: Large temperature error, high design redundancy cost.
Space restrictions: Small bearing inner diameter and winding gap size, limiting probe installation.
Rotating parts cannot be wired.
Temperature measurement: Motor winding temperature is high, and traditional sensors are damaged due to excessive temperature.
Lingee Solutions
To ensure the safe operation of motors (and extend their service life), our company has developed and produced an NTC temperature sensor:
1) Micro-size: The probe size can be as small as 0.55 mm, suitable for the narrow internal space of some motors, and flexible to install.
2) Wide temperature range: -50 to 350°C, covering the main operating temperature range of motors.
3) High accuracy: Temperature measurement accuracy up to ±0.1°C.
4) Customization: Structure dimensions can be customized according to motor type.
