Motor thermistor protection
Nettet2. apr. 2024 · Thermistors are built into the motor windings and protect the motor against locked rotor conditions, continuous overload and high ambient temperature. The symbol for a thermistor is shown below: Thermal protection is then achieved by monitoring the temperature of the motor windings with PTC sensors. NettetLike thermostats, thermistors have a tamper proof pre-set switch point, with a reset only after the motor cools down. Due to their small size and heat sink construction, they …
