Motor protector is a device used to protect a motor from abnormal operating conditions. In the field of automotive motors, motor protectors play a crucial role in ensuring the normal operation and safety of the vehicle. In cars, the main function of an electric motor is to generate rotational motion and drive the vehicle forward or backward. The task of the motor protector is to monitor the operating status of the motor and take corresponding protective measures in case of abnormal situations. The application range of motor protectors is wide, including car starters, generators, seat motors, wiper motors, pedal motors, window lifter motors, sunroof motors, tailgate motors, etc. These devices require monitoring and protection of motor protectors to ensure their normal operation under various conditions. The functions of motor protectors mainly include overload protection, phase failure protection, short circuit protection, undervoltage protection, etc. Overload protection can prevent the motor from overheating and burning out; Phase failure protection can protect the motor in the event of power interruption or motor winding failure; Short circuit protection can prevent excessive current caused by winding short circuits; Undervoltage protection can prevent the motor from operating normally due to low voltage. The existence of motor protectors can greatly improve the reliability and safety of automotive motors, and extend their service life. At the same time, it can also reduce maintenance costs and downtime, providing strong guarantees for the normal operation of the car. In the future, with the continuous development of automotive technology, the requirements for motor protectors will also become increasingly high. HCET has obtained international certification at the IATF16949 vehicle specification level. Each motor protector production follows European RoHS environmental standards and strict quality control, ensuring product quality. Haichuan provides you with professional comprehensive solutions for automotive motors.

Thermal protector is a device used to protect a motor from overheating damage. In the field of motors, thermal protectors are widely used in various types of motors, and they are applied in the following aspects: Oil pump motor The oil pump motor is the core component, and it generates heat during operation. If the heat is too high, it can cause the motor to overheat or even be damaged. In order to protect the oil pump motor from overheating damage, a thermal protector is usually used to monitor the motor temperature. When the temperature exceeds the set threshold, the thermal protector will trigger a protection mechanism and take measures such as power outage to protect the motor. Electric tools Electric tools generate a large amount of heat during operation. To ensure the safe use of electric tools, thermal protectors are usually equipped to monitor the motor temperature. When the temperature is too high, the thermal protector can automatically cut off the power supply to prevent damage to the motor due to overheating. In addition, thermal protectors can also prevent overcharging of the battery, thereby protecting its lifespan. Washing machine motor The washing machine requires a lot of rotation and flipping during the washing process, so the washing machine motor also needs to operate under high loads. In this case, the thermal protector can monitor the temperature of the washing machine motor to ensure that the motor will not overheat and be damaged. When the temperature is too high, the thermal protector will automatically cut off the power supply and sound an alarm, reminding users to check or repair the washing machine motor. Motor of soybean milk machine The soybean milk machine needs to use a motor to drive the blade to rotate at a high speed during the production of soybean milk. During this process, if the motor overheats, it may cause damage to the motor. Therefore, the thermal protector is often used in the soybean milk machine to monitor the temperature of the motor. When the temperature is too high, the thermal protector can automatically cut off the power supply and remind the user to take measures to cool down or repair the soybean milk machine. In summary, thermal protectors have extensive application value in the field of motors. For oil pump motors, electric tools, washing machine motors, soybean milk machine motors and other equipment, the existence of thermal protectors can effectively avoid damage and potential safety hazards caused by overheating, and they are also more widely used in other motors.

Bimetal Thermal switches are widely used in the heating field, such as seat heating, electric blankets, heating pads, floor heating devices, etc. A temperature control switch is a device that uses temperature changes to control the opening and closing of a circuit. When the temperature rises, the temperature control switch will automatically disconnect the circuit to prevent overheating; When the temperature drops, the temperature control switch will automatically turn on the circuit to maintain temperature stability. The temperature control switch consists of two parts: a bimetallic sheet and a contact point. The bimetallic sheet senses temperature changes, and the contact point controls the opening and closing of the circuit. 1. Seat heating: Seat heating is the application of temperature control switches on car seats. By installing a temperature control switch on the surface of the seat, the temperature of the seat can be sensed and the circuit can be automatically adjusted according to temperature changes, thereby controlling the power output of the seat heater. In this way, the seat heater can provide a comfortable riding environment for passengers in cold weather. 2. Electric blanket: Electric blanket is another heating product that uses a temperature control switch. In an electric blanket, a temperature control switch can sense the user's body surface temperature and automatically adjust the circuit's on-off according to temperature changes, controlling the power output of the electric hot wire. In this way, the electric blanket can provide users with a warm sleep environment on cold nights. 3. Heating pad: A pad for people or pets to use, which has functions such as warmth preservation, comfort, and disease prevention. In the pet mat, the temperature control switch can sense the temperature of the pet's body and automatically adjust the circuit's on-off according to temperature changes. In this way, the heating pad can provide a comfortable resting environment for humans or animals in cold weather. At the same time, the temperature control switch can also prevent the heating pad from overheating, thereby ensuring the safety of pets. In summary, bimetal thermal switches have a wide range of applications in the heating field, providing people with a safe and comfortable working or living environment.
