Thermistor..

Answer 2

Generally, the temperature sensor is used to protect Electric Motor

• Electric motor protection frequently involves the use of temperature sensors.
• These sensors can be used to monitor the temperature of the motor or any of its parts, including the winding or bearing, and shut down the motor if the temperature rises above a predetermined level.
• This can assist in avoiding overheating, which can harm the motor and lower its efficiency.
• Other types of sensors, such as current sensors and voltage sensors, can be utilised in conjunction with temperature sensors.
• The voltage sensors, for instance, can be used to gauge the voltage supplied to the motor or its power source and, if the voltage deviates from a predetermined range, to cause an alarm or shutdown.
