Suitable for large car wiper motor thermal protector------8AM thermal protector

The function of the car wiper is to clear the rain or snow on the windshield when driving in rainy and snowy weather, so as to ensure that the driver has a good line of sight.

Whether the wiper can operate normally is related to the safety of the driver and the people on board, so the safety protection of the wiper is very important.

The core component of the car wiper is a micro DC motor, which is driven through a linkage mechanism to make the wiper blade on the outer surface of the windshield swing back and forth to sweep away rain, snow or dust on the windshield.The working principle of the wiper is that the micro DC motor, the turbine box and the motor are assembled together and fixed on the bottom plate. The rotation of the turbine is converted into a cylindrical swing through the crank, connecting rod, swing rod and other transmission mechanisms, and the wiper is driven by the swing arm. The blades swing back and forth, and the wiper rubber removes obstacles on the windshield that block the line of sight.

When the wiper is dry for a long time or the wiper is frozen in winter, the motor is prone to stall and overload, which will cause the motor to be burned and the wiper to fail. Therefore, it is very necessary to install a thermal overload protector switch. The thermal protector can avoid the problem of motor burnout. When the motor is overheated, the thermal protector can control the circuit on and off to protect the safety of the motor and improve the reliability of the motor. The thermal protector switch is connected in series to the public carbon brush of the wiper motor, and for low-speed or high-speed work to play an overload protection role.

8AM series thermal protector for motor can have dual protection functions of temperature and current overload at the same time, and the current trip value can reach 60A, with large electrical capacity and high reliability.Widely used in large-scale automobile wiper motors, water pumps, and other motors.
