Why thermal switch is vital for wiper motor

               The importance of temperature switch for wiper motor - 【 HCET Haichuan Electronics 】

The wiper motor is an important component in cars, its function is to drive the movement of the wiper, helping to remove water droplets, rainwater, and other debris from the windshield, ensuring a clear view of the driver. In the event of rain or dust or other pollutants, using a wiper motor can improve driving safety and comfort.

During the operation of the wiper motor, a certain temperature is generated due to energy consumption and heat generation. At the same time, due to the high resistance of the wiper during operation, the motor load and current will increase, resulting in more obvious  internal  heating of  the motor. If the motor is operated  for a long time or the load is too large, and it is not cooled down in a timely manner, it will cause the motor to overheat and be damaged.


In addition, the normal operation of the wiper is also affected by factors such as environmental temperature, humidity, and wind speed. If the internal heat dissipation of the motor is poor in high temperature, humidity, or wind speed environments, it will also exacerbate the overheating phenomenon of the motor, ultimately leading to motor damage.

A wiper  motor thermal protector   is an overload protection device that can automatically cut off the circuit when the motor load is too high or the temperature is too high, avoiding damage to the motor due to overload or overheating.


Motor protector

The 5AP series thermal switch temperature controller  is a temperature switch specifically designed for motor protection, with the following advantages:


1. Micro size: The 5AP series temperature switch adopts a micro package, which is compact and easy to install in narrow spaces such as wiper motors, improving the flexibility and comprehensive performance of the product.


2. Accurate tripping: The 5AP series thermal cutoff  switch can select products of different types and rated temperature ranges according to user needs and usage conditions, and undergo strict testing and calibration during the design and manufacturing stages to ensure its tripping accuracy, reliability, and stability.


3. High sensitivity: The 5AP series temperature switches use bimetallic plates as sensitive components, which have high sensitivity and response speed. They can be triggered in a timely manner when the motor is overloaded or overheated, cut off the circuit, and protect the safe and stable operation of the motor and the entire electrical equipment.


4. Good insulation performance: The 5AP series automotive motor thermosotat switches have good insulation performance, comply with relevant international standards, and can work safely for a long time in high temperature environments ranging from -40 ℃ to 180 ℃.


Therefore, the 5AP series bimetal thermost is a motor protector with small size, precise tripping, high sensitivity, and good insulation performance, which has particularly significant application effects in narrow spaces such as wiper motors.
