Function in motor application

1. If the temperature of the motor winding exceeds the maximum rated temperature, the winding may be damaged, or the motor insulation may be damaged or even completely fail. This is why most electric motors and gear motors (especially those used in motion control applications) integrate a thermistor or silicon resistance sensor (also known as a KTY sensor) into the motor winding. These sensors directly monitor the winding temperature (rather than relying on current measurement) and are used in conjunction with protection circuits to prevent damage due to high temperatures.

2. Another 1 type of positive temperature coefficient sensor is a silicon resistance sensor, also known as a KTY sensor (the family name given to this type of sensor cnampfortby the original manufacturer of the KTY sensor). These PTC sensors are made of doped silicone and manufactured using a process called diffused resistance, which makes the resistance almost independent of manufacturing tolerances. Unlike PTC thermistors, which rise sharply at the critical temperature, the resistance-temperature curve of the KTY sensor is almost linear. of a nature.

3. KTY sensors have a high degree of stability (low thermal drift) and a nearly constant temperature coefficient, and are also generally cheaper than PTC thermistors. Both PTC thermistors and KTY sensors are commonly used to monitor winding temperature in motors and gear motors, while KTY sensors are more common in large or high-value motors (such as iron-core linear motors) due to their high precision and linear characteristics.
