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 decrease
Instability 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 stator
The rectifier converts three-phase AC power into DC power
Voltage regulator controls the magnetic field of the rotor to regulate the generator voltage
Functional 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:
- The high and low temperature resistance of the adhesive (automotive grade -40-125 ℃)
- Adhesive force between glue and shell, wire harness (usually the product material does not peel off under high and low temperature impact or cycling)
- Flame retardant grade 94V-0
- Operability of adhesive products (surface drying and curing time, product appearance)
