When to choose 6-tube: Light-duty applications, e-bike conversions, urban passenger tricycles on flat roads, entry-level fleet procurement with tight per-unit cost targets.
When to choose 12-tube: Heavier passenger loads, hilly terrain, or when the vehicle may be upgraded to 650W/800W motor in a future model year.
Square Wave vs PMSM — Technology Choice for 6-Tube
6-tube is only available in square wave. For PMSM (sine wave) motors at the 500W power level, Kehuan offers the 12-tube permanent magnet synchronous controller as the entry point into the PMSM product line. The 6-tube square wave controller is the correct match for standard brushless DC motors used in entry-level e-bikes and light tricycles.
For B2B buyers comparing options, "6 MOSFET brushless controller for e-rickshaw" is a common search formulation in sourcing platforms. Kehuan's 6-tube controller meets the same specification profile as "6 MOSFET" listings, using the tube-count nomenclature standard in Chinese manufacturing and the MOSFET-count nomenclature standard in international B2B platforms.
Why Choose Kehuan 6-Tube Controller
- 18A stable output. Many entry-level controllers rate at 18A but thermally throttle above 12A. Kehuan's 6-tube controller sustains the full 18A under continuous 500W motor load — the power delivery matches the rating on the specification sheet.
- 48V/60V/72V auto-detection. One controller covers three battery platforms. For B2B buyers managing mixed-voltage light e-trike or e-bike product lines, this eliminates separate SKUs for each voltage. One part number, one inventory bin, one wiring diagram across all three platforms.
- 13 years of controller-only focus. Since 2011, Kehuan has specialized exclusively in brushless controllers for electric tricycles and e-bikes. Over 1000 B2B clients across 2014–2024 have standardized on Kehuan controllers as their primary drive system component. This 6-tube model benefits directly from the same R&D pipeline that develops the 12-tube, 18-tube, and 24-tube product lines.
