Controllers

E-bike Motor Controllers

FOC-ready motor controllers engineered for OEM e-bike integration, thermal margin, and certification readiness—delivered with CAN/UART interface mapping, tuning baseline, and validation evidence.

What it is

Our electric bicycle motor controller platform targets 36V–48V systems with stable torque delivery, predictable derating behavior, and serviceable firmware/tuning workflow—built for program phases from EVT to mass production.

What you get

What you get as an integration-ready package for e-bike controller OEM programs:

  • System responsibility matrix (controller vs BMS vs pack): limits, derating, fault handling
  • Interface mapping (CAN/UART + wiring/pinout): versioned documentation for integration and service
  • Tuning baseline: parameter set + change log aligned with duty cycle targets
  • Validation evidence package: test plan + pass/fail summary + issue log
  • Production handoff checklist: QA gates, release artifacts, traceability fields (program-defined)

Typical requests include torque sensor / cadence sensor compatibility, peak current limit, thermal derating curve, and CAN message mapping for fleet/service tools.

Integration workflow

Define duty cycle targets → lock interface mapping (CAN/UART + pinout) → establish tuning baseline → validation plan & evidence → production handoff & traceability.

Typical KPIs

  • Thermal headroom at target duty cycle (°C margin)
  • Torque smoothness / response stability
  • Fault coverage & recovery behavior (cutoff / limp / retry logic)
  • Integration lead time (first rideable build to validated baseline)
