Intelligent Programming brushless DC Motor Controller DK72240 sine Control 65A Version is Suitable for QS Motor Electric Motorcycles and Electric Scooters. Transparent

Give your 72-volt build a refined, service-friendly brain. The DKYS DK72240 (65A) is a transparent, sine-wave FOC controller built for QS Motor electric motorcycles and scooters. Its sealed, clear housing helps protect internal electronics while making indicator LEDs visible—so installers can verify power, halls, and faults in seconds. FOC sine control means quiet operation, crisp low-speed control, and improved efficiency. Setup is straightforward: run auto hall/phase learn, choose a ride profile, then fine-tune current limits, throttle map, and regen strength. Safety comes first with over-current, over/under-voltage, over-temperature, and phase-fault protection. For riders who want more top-end, flux-weakening is available within motor limits.

• 【Transparent, Sealed Design】Clear, potted enclosure helps resist dust/splash* and lets you see status LEDs at a glance—handy for diagnostics and pro installs.
• 【72V 65A Class, Smooth FOC Drive】Sine-wave field-oriented control delivers quiet starts, linear throttle, and strong low-speed torque for city rides or hill climbs.
• 【QS Motor Ready】Works with popular QS hub or mid-drive motors; auto hall/phase identification with sensorless fallback for quick commissioning.
• 【unable Ride Profiles】Set Eco/City/Sport, adjust battery/phase current, throttle curve, and regenerative braking strength (lever-activated and coasting regen supported).
• 【Installer-Friendly Wiring】Clearly labeled low-voltage leads (throttle, brake, 3-speed, reverse/ignition) and heavy-duty power/phase terminals; PC programming (optional BT module).
