PTC thermistors, or Positive Temperature Coefficient thermistors, are widely used in various applications for motor protection and temperature sensing.
PTC thermistors are thermally sensitive semiconductor resistors whose resistance increases sharply when a certain temperature is exceeded. This feature makes them ideal for use in countless applications of modern electrical and electronic engineering, such as resettable fuses against current overload or as short-circuit protection in motors
Applications in Motors:
PTC thermistors are used for thermal protection of electrical machines, particularly as motor protectors. They can be embedded within the insulation of a motor winding to provide a close thermal association with the winding. They are known for their rapid response protection for electrical machines and compact size for easy assembly into windings
