How to use PTC thermistors as current protection ...

PTC thermistors can effectively protect motors from such overcurrent. For example, if the side mirror of a car is blocked by an object, the motor will lock when an attempt is made to set the mirror or retract it. This will result in an overcurrent through the motor winding. In order to protect against thermal overstress a PTC thermistor is used.

THERMISTOR BASICS – Wavelength Electronics

Temperature Range: The approximate overall range of temperatures in which a sensor type can be used. Within a given temperature range, some sensors work better than others. Relative Cost: Relative cost as these sensors are compared to one another. For example, thermistors are inexpensive in relation to RTDs, partly because the material of choice for RTDs is platinum.

What is a Thermistor? How do thermistors work? - EI Sensor ...

A thermistor is a temperature sensor whose electrical resistance changes in response to a change in body temperature. Though the initial concept of an NTC thermistor was first reported in 1833 by Michael Faraday, when he discovered the effect of temperature on silver sulfide, it wasn’t until the 1930’s when the first commercial thermistors were produced.

Thermistor Motor Sensing Protection - AMWEI Thermistor Sensor

PTC Thermistors are widely employed as temperature sensors in electrical machines to monitor winding temperature. In this case, the PTC Thermistor is wound directly into the winding so that direct thermal contact is produced. The abrupt increase in the resistance of the thermistor at high temperatures can be used as a control signal for the tripping unit.
