The stepper motor is a crucial component in a vehicle’s engine, mounted on the throttle valve. This electronic-mechanical part regulates the airflow to the throttle valve and keeps the vehicle running smoothly. It is installed at the intake of the throttle valve and can become contaminated with soot, oil, and airborne particles. This contamination can disrupt the stepper motor’s functionality, so it is essential to clean it regularly to prevent engine damage.
Components of the Stepper Motor:
1. Electric Motor 2. Retaining Spring 3. Separator Bushing 4. Stepper Shaft 5. Cap
In domestic vehicles, exhaust smoke and oily gases from the engine enter the intake manifold and are re-sucked by the engine. This problem causes grease and soot buildup on the throttle valve components, which is a major factor in damaging these parts. In the AGU stepper motor, the housing is designed with a fully sealed front section, preventing soot, oil vapor, and returning fuel vapor from entering the stepper motor. The bearing used in the AGU stepper motor is a type 706 bearing, which, due to its larger size, is highly resistant to soot and contaminants.
The bearing connection to the rotor in the AGU stepper motor is designed with screws to minimize the risk of the bearing separating from the rotor. The connection of the coil and connector in the AGU stepper motor is designed to ensure both mechanical and electrical connections, eliminating the possibility of disconnection under any conditions. The lacquered wire used in the AGU stepper motor is a two-layer type, reducing the risk of short circuits between the coil winding layers.
Do not replace the stepper motor solely because of high engine RPM, RPM fluctuations, engine stalling, or reduced RPM!
First, use a diagnostic tool to confirm any issues with the stepper motor before proceeding with its replacement.
The materials used in the stepper motors from Union Golden Asia comply with domestic automotive standards and, due to specialized testing and performance evaluations, offer greater durability and better performance compared to other stepper motors on the market.
Signs of Stepper Motor Failure:
1. Engine RPM increases after starting the vehicle.
2. The vehicle stalls after releasing the gas pedal.
3. Engine RPM decreases when additional loads, such as the air conditioning, are applied.
4. RPM is unstable when the vehicle is idling.
5. The vehicle idles erratically without apparent reason.
6. Engine temperature causes an increase in RPM.
