Avetlink AK 12-Tube Brushless Controller for Reliable Cargo Transport
Sudden load changes during climbing or braking can cause excessive current and damage controller MOSFETs. Frequent failures increase repair costs and may also affect the motor and rear axle system.
The Avetlink AK 12-tube brushless controller combines fault-tolerant operation, electrical protection, and flexible voltage compatibility to support demanding daily use.
Three Main Features
- Automatic sensorless operation: If a Hall sensor fails, the controller switches to sensorless mode. The vehicle may need to be pushed until the wheel turns once before motor drive resumes.
- Multiple protection functions: E-ABS braking voltage control and phase-wire short-circuit protection help protect the controller against braking-related voltage surges and wiring faults.
- Flexible compatibility: Supports 48V / 60V batteries and 500W–800W motors. Three speed settings help match power delivery to different loads and climbing conditions.

Reported Performance
The supplied product information reports:
- 30 short-circuit events without controller damage.
- 15% longer driving range.
- 80% fewer load-related failures.
- Three times faster current response when rear axle loads change.
- Two additional years of battery service life through controlled low-voltage protection.
- A temperature rise 40°C lower than a conventional controller during a motor stall test.
Additional Features
- Effective cooling: A heavy-duty aluminum heat sink and dynamic temperature control help manage heat.
- Anti-theft motor locking: When activated, the system applies reverse motor torque to resist attempts to push the locked vehicle.
- Self-learning wiring: Supports 60° / 120° Hall configurations and automatically identifies the wiring sequence. The self-learning connection also allows motor rotation direction to be adjusted.
Maintenance Tips
1. Clean dust, lint, and other debris from the heat sink every month, especially on cargo tricycles.
2. Use suitable sealant around the control box base for moisture protection, keeping cooling and drainage openings clear.
3. For loads above 800 kg, use the low-speed setting only if the vehicle is rated to carry that load. Low gear does not increase the vehicle’s rated load capacity.
The Avetlink AK controller offers coordinated protection, flexible setup, and responsive power control for compatible electric tricycles.
