Fockety 36V 350W Brushless DC Motor Controller User Manual

1. Product Overview

The Fockety 36V 350W Brushless DC Motor Controller is designed for electric scooters, electric bicycles, and electric tricycles. It provides stable speed control and sensitive response for braking and direction changes. The controller features a durable aluminum alloy casing with a groove design for efficient heat dissipation, protecting internal circuitry from thermal overload. All wires are constructed from high-temperature resistant and flame-retardant materials for enhanced safety.

This controller incorporates multiple protection functions, including undervoltage protection, overcurrent protection, and stall protection, ensuring reliable performance and user safety.

2. Safety Information

• Always disconnect power before installation, maintenance, or troubleshooting.
• Ensure all connections are secure and correctly insulated to prevent short circuits.
• Do not expose the controller to water or excessive moisture.
• Verify that the voltage and power ratings of your motor and battery match the controller's specifications (36V, 350W).
• Professional installation is recommended for electrical components to ensure proper function and safety.
• Keep the controller away from flammable materials.

4. Installation and Setup

Important: This controller does not come with a specific wiring diagram. It is crucial to identify each wire function correctly before making any connections. If you are unsure, consult a qualified technician.

4.1 General Connection Guidelines

1. Power Supply: Connect the main power wires (typically red for positive, black for negative) from your battery to the corresponding terminals on the controller. Ensure correct polarity.
2. Motor Connections: Connect the motor phase wires (usually three thick wires, e.g., blue, green, yellow) from the motor to the controller.
3. Hall Sensor Wires: Connect the Hall sensor wires (typically five thin wires) from the motor to the controller's Hall sensor port. These provide feedback for motor commutation.
4. Throttle: Connect the throttle wires to the designated throttle input on the controller.
5. Brake Levers: Connect the brake lever wires. These typically cut power to the motor when brakes are applied.
6. Other Connections: Depending on your setup, there may be additional connections for display, lights, cruise control, etc. Refer to your specific vehicle's wiring for these.

After making all connections, secure the controller in a protected location, ensuring adequate airflow for heat dissipation. The aluminum alloy casing with its groove design aids in this process.

5. Operation

Once correctly installed and powered, the controller manages the electric motor based on user input (e.g., throttle, brake). It provides a stable and responsive control experience.

• Power On: Turn on the main power switch of your electric vehicle.
• Throttle Control: Gently apply the throttle to accelerate. The controller will regulate power to the motor for smooth speed changes.
• Braking: Activating the brake levers will signal the controller to cut power to the motor, allowing the vehicle to slow down or stop.
• Protection Features: The controller will automatically engage its protection mechanisms (undervoltage, overcurrent, stall protection) if abnormal conditions are detected, helping to prevent damage to the system.

6. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your controller.

• Keep Clean and Dry: Periodically clean the exterior of the controller to remove dust and debris. Ensure it remains dry and protected from water ingress.
• Inspect Connections: Regularly check all wire connections for tightness and signs of wear or corrosion. Loose connections can lead to intermittent operation or damage.
• Ventilation: Ensure the controller's mounting location allows for adequate airflow to facilitate heat dissipation. Do not obstruct the cooling fins.
• Avoid Physical Damage: Protect the controller from impacts or excessive vibration.

7. Troubleshooting

If you encounter issues with your controller, consider the following troubleshooting steps:

• No Power:
  • Check battery charge level.
  • Verify main power connections to the controller are secure and correctly polarized.
  • Inspect the main power fuse (if applicable) for your vehicle.
• Motor Not Responding/Intermittent Operation:
  • Check all motor phase wire connections.
  • Verify Hall sensor wire connections.
  • Inspect throttle connections and functionality.
  • Ensure brake levers are not stuck in the 'on' position, which would cut motor power.
• Overheating:
  • Ensure the controller is mounted in a location with good airflow.
  • Check for excessive load on the motor or vehicle.
• Protection Mode Activated:
  • If the controller enters a protection mode (e.g., motor stops, power cuts), identify the cause (low battery, overcurrent, motor stall) and rectify it before resuming operation.

If the problem persists after these steps, it is recommended to seek assistance from a qualified technician.
