Avetlink AK Six-Tube Controller for Heavy-Load Electric Tricycles
Poor current control and heat dissipation can cause uneven motor power and frequent shutdowns during loaded hill climbing. Uneven power delivery can also increase wear on the rear axle.
Drivers in the supplied text described controllers becoming extremely hot while the motor continued to hesitate under load.
The Avetlink AK six-tube controller uses a six-IGBT power module, vector control, and intelligent temperature management to support smoother power delivery and manage heat.
Reported Performance
The original product description reports:
- 40% better current output accuracy.
- Module temperature maintained below 70°C during continuous heavy-load operation.
- 30% faster power response when carrying 800 kg up a 15° slope.
- 50% less rear axle gear wear under the described operating conditions.
Three Main Features
1. Smooth Starting Power
The six-tube drive design controls starting current more precisely, helping reduce sudden forward jolts and uneven acceleration.
2. Effective Heat Dissipation
An aluminum alloy housing and cooling fins help release heat. The source reports 60% higher heat-dissipation efficiency than the compared plastic housing, supporting operation in hot conditions.
3. Flexible Voltage Compatibility
The controller supports 48V–60V input and compatible motor and battery configurations. This provides more replacement options and can reduce modification costs.
Customer Feedback from the Supplied Reference Case
Building-material transporters in Sichuan reported:
“We used to stop three times a day to let the controller cool down. Now we can complete three trips in one go.”
This feedback is retained as an original reference case, rather than a verified Avetlink customer testimonial.
Maintenance Tips
Disconnect power and let the equipment cool before maintenance.
1. Cooling system: Check cooling openings daily, remove dust with compressed air weekly, and check fan operation monthly.
2. Electrical connections: Inspect controller and motor connections every 500 km. Tighten loose terminals according to the specified tightening requirements to reduce poor contact and heat buildup.
3. Load placement: Secure cargo evenly and stay within the vehicle’s rated payload. The source recommends a cargo center-of-gravity offset of ≤15 cm, but the reference point needs clarification.
