2.3 Motor Installation (Razor Upgrade Example)

The KR5V motor is suitable for various applications, including Razor upgrade kits, electric dirt bikes, go-karts, and ATVs. The following steps demonstrate a typical installation process for a Razor upgrade.

1. Uklonite stare komponente: Carefully remove the existing motor and any associated accessories from your vehicle.
2. Mount the KR5V Motor: Position the KR5V motor in the desired location. Ensure proper alignment for the chain and sprocket. The motor supports two mounting methods: front/back or bottom.
3. Osigurajte motor: Use appropriate fasteners to securely attach the motor to the vehicle's frame.
4. Install Sprocket and Chain: Attach the appropriate sprocket (compatible with #35 chain) to the motor shaft. Install the chain, ensuring proper tension.

2.4 Spajanje ožičenja

Connect the motor to a compatible 72V BLDC motor controller (suggested 80-100A controller). Ensure all connections are secure and correctly polarized.

• Connect the motor's phase wires (typically three thick wires) to the corresponding terminals on the controller.
• Connect the Hall sensor wires (smaller wires) from the motor to the controller's Hall sensor input. If your controller is not a Fardrive or Kerry controller, a separate Hall adapter wire may be required.
• Connect the main power wires from your battery to the controller.
• Connect other accessories such as the throttle, ignition switch, and display as per your controller's instructions.

3. Upute za rad

After successful installation and wiring, ensure all connections are tight and secure before operating. Turn on the ignition (if applicable) and gently apply the throttle to test motor function. Observe for smooth operation and any unusual noises.

Sigurnosna napomena: Do not touch the motor with your body when it is working, as it can become hot and cause burns.

4. Održavanje

Regular maintenance ensures optimal performance and longevity of your KR5V motor.

• Redoviti pregled: Periodically check all electrical connections for tightness and signs of wear or corrosion.
• Čišćenje: Keep the motor housing clean, especially the heatsink fins, to ensure efficient air cooling. Use a dry cloth or soft brush.
• Praćenje temperature: Utilize the KTY84-130 temperature sensor with a programmable BLDC motor controller to monitor and adjust operating temperature, protecting the motor from overheating.
• Hall Sensor Care: The Hall sensor is external for easier maintenance. Do not remove the screws on the Hall sensor, as this can affect motor operation.
• Lanac i lančanik: Inspect the chain and sprocket for wear and proper tension. Lubricate the chain as needed.
