Avetlink AK 24-Tube Drive System for Heavy Cargo
When a controller cannot meet the vehicle’s power needs, heavy loads and hill climbing can cause weak acceleration, overheating warnings, and uneven motor output. These problems can also increase stress on the rear axle and reduce driving range.
One driver in the supplied text described the problem: “When carrying half a ton through a tunnel, the motor shook badly and the controller kept flashing.”
Coordinated Controller, Motor, and Rear Axle
The Avetlink AK system combines a 24-tube controller, a 3000W permanent magnet synchronous motor, and a rear axle with hardened components.
The controller coordinates current delivery to support smoother, stronger motor output. The original description reports:
- 80% more torque than the compared 12-tube system.
- A 40°C reduction in motor temperature rise while carrying 1,500 pounds up a 25° slope.
- A threefold increase in rear axle gear life.
- A power response time of 0.2 seconds.
These figures describe the complete vehicle configuration, rather than improvements determined by controller tube count alone.
Three Key Features
1. Coordinated Power Control
The 24-tube power stage distributes current with millisecond-level timing. The source reports starting torque of up to 100 N·m, supporting smoother starts and stops under load.
2. Active Cooling
A graphene heat sink and temperature-controlled fan help manage heat. Strong cooling mode activates at 70°C.
The source lists IP68 protection and a 50 cm water-depth capability. The applicable test conditions and protection scope need confirmation.
3. Reinforced Rear Axle
The rear axle uses an automotive-style differential and double-row tapered roller bearings. Its reported load-bearing limit is 2,000 kg; this is an axle specification, not automatically the vehicle’s permitted cargo load.
Customer Feedback from the Supplied Reference Case
The Hebei Coal Transport Team reported:
“After switching to the 24-tube system, we could carry 600 more pounds per trip and needed three fewer vehicle repairs per month.”
This is retained as a reference case from the original material, rather than a verified Avetlink customer testimonial.
Maintenance Tips
1. Weekly controller inspection: Use an infrared thermometer to check the module. The source specifies a temperature difference of no more than 5°C between inspected components.
2. Motor cooling and lubrication: After heavy-load operation, let the equipment cool before cleaning cooling openings with compressed air. Service the bearing grease every 5,000 km, following the motor’s maintenance instructions.
3. Rear axle lubrication: Check gear oil every 1,500 km. Replace deteriorated or contaminated oil, and keep the level between the dipstick’s upper and lower marks.
