Application of Elaplus Adhesive in Automotive Regulators

2025-03-31

What is a car motor regulator?The power supply system of a car is composed of a car battery and a generator. The generator is responsible for charging the battery and keeping it in a fully charged state for a long time. The battery and generator are responsible for supplying power to the electrical appliances of the entire vehicle. Due to the fact that the generator is driven by the car’s engine, and the engine speed is not constant, it can cause the output voltage of the generator to decreaseInstability requires an electronic device to control the generator, so that the generator can output a relatively stable voltage at different speeds of the car engine.In addition, when the generator is charging the battery, it is necessary to prevent excessive charging current, and this electronic device also needs to have a current limiting function.The rotor is first energized to generate a magnetic field;The rotation of the rotor can generate three-phase AC power in the statorThe rectifier converts three-phase AC power into DC powerVoltage regulator controls the magnetic field of the rotor to regulate the generator voltageFunctional requirements of adhesive for automotive motor regulators The main function of the regulator is to achieve stable control of the generator voltage, usually focusing on electrical insulation and the high and low temperature resistance of the product; Require the adhesive to maintain good electrical stability even under various simulated testing conditions after curing.Focus on adhesive performance:
