4. Konfiguracja i instalacja
Proper installation is crucial for the safe and optimal performance of your motor kit. While specific installation steps may vary depending on your application (e.g., electric bike, scooter, go-kart), the general principles remain consistent.
4.1 Środki ostrożności
- Ensure the power source is disconnected before beginning any installation or wiring.
- Należy nosić odpowiedni sprzęt ochrony osobistej (PPE), taki jak rękawice i okulary ochronne.
- Jeśli masz jakiekolwiek wątpliwości, skonsultuj się z wykwalifikowanym technikiem.
4.2 Identyfikacja komponentów
Familiarize yourself with each component of the kit. The motor has a T8F 11-tooth sprocket. The controller is the central unit for managing power and motor speed.

4.3 Mounting the Motor and Controller
- Securely mount the motor to your vehicle's frame using appropriate fasteners. Ensure it is stable and aligned with the drive system (e.g., wheel, axle).
- Mount the controller in a protected area, away from direct moisture, excessive heat, and physical impact. Ensure adequate ventilation for natural air cooling.
4.4 połączeń przewodów
Carefully connect all components to the controller. The controller has designated ports for the motor, twist grips, electric door lock, and power supply. Ensure all connections are firm and correct according to the wiring diagram (if provided with your specific vehicle or controller model). Important: Connect all necessary accessories before plugging in the power supply.
4.5 Chain and Sprocket Installation
- Install the chain onto the motor's sprocket and the driven sprocket on your vehicle.
- Adjust chain tension to ensure it is not too tight or too loose, allowing for smooth operation without excessive slack or binding.
5. Instrukcja obsługi
Once the kit is fully installed and all connections are secure, you can begin operating your electric vehicle.
5.1 Włączanie/wyłączanie
- Insert the key into the electric door lock and turn it to the "ON" position to power on the system.
- Turn the key to the "OFF" position to power off the system.
5.2 Speed Control (Twist Grip)
The twist grip allows you to control the motor's speed. It features a 3-speed selection:
- Niska prędkość: Provides gentle acceleration and lower top speed, suitable for precise control or navigating crowded areas.
- Średnia prędkość: Offers a balanced performance for general riding conditions.
- Wysoka prędkość: Delivers maximum power and top speed for open areas or when higher performance is desired.
Twist the grip to increase or decrease speed. The specific mechanism for selecting between low, medium, and high speeds is typically integrated into the twist grip or a separate switch connected to it.
5.3 Sterowanie kierunkiem
The twist grip also includes a function button for forward and reverse operation. Press or toggle this button to switch the motor's direction as needed for your application.
