Wholesale 18-Tube Aluminum Substrate Brushless Controller

Conventional controllers use FR-4 fiberglass boards. Heat concentrates at MOSFET junctions, creating localized hot spots that degrade solder joints and eventually cause board-level failure. The KH 18-tube controller uses an aluminum substrate PCB — a metal-core circuit board that spreads heat across the entire board surface, reducing thermal resistance by approximately 40%. This is why the 18 tube brushless controller for cargo tricycle design philosophy extends to every current rating we produce: thermal management first, then power delivery.

 

Current limit is not just a safety feature. It determines whether your tricycle maintains consistent speed under cargo load or slows down as the controller throttles power to protect itself. The KH 18-tube controller delivers 40A–45A sustained output without thermal throttling, meaning cargo tricycles maintain rated speed even when fully loaded — no slowdown, no rider complaints, no fleet performance inconsistencies.

 

Kehuan has manufactured electric tricycle controllers since 2012 — not motors, not batteries, not accessories. Controller technology is our core competency, backed by >5% annual R&D investment and a university-industry partnership with Guilin University of Electronic Technology since 2016. 1,000+ B2B clients across Southeast Asia rely on Kehuan controllers for daily fleet operation.

 

Kehuan supplies complete electric tricycle drive systems — not just controllers. When you source from us, you also gain access to compatible Electric Motor units, Electric Tricycle Differential Box assemblies, and Electric Cargo Tricycle platforms — all designed to work together, eliminating cross-supplier compatibility risks.
