Nucular 12F FOC Controller Kit

The Nucular 12F FOC Controller Kit is a boutique, ultra-compact motor controller celebrated worldwide for its surgical throttle modulation, velvety smooth sinusoidal power delivery, and dedicated handlebar telemetry display. While many aftermarket controllers rely entirely on external smartphone apps, Nucular engineered an integrated onboard color micro-display that puts complete system control directly at the rider's fingertips.

Engineered with advanced 32-bit Field-Oriented Control (FOC) vector algorithms, the Nucular 12F continuously calculates rotor magnetic flux angles, pulsing pure sinusoidal current into the motor windings. This eliminates low-speed throttle jerkiness, reduces electromagnetic motor hum to zero, and provides whisper-quiet operation.

The Nucular 12F operates across an input voltage range up to 20S (84V peak), making it fully compatible with stock 60V batteries as well as high-output 72V aftermarket battery packs. The compact aluminum enclosure acts as a conductive heatsink that mounts cleanly within the Sur-Ron frame cavity.

Onboard Micro Display & Telemetry: The weatherproof handlebar display allows riders to toggle between four customizable riding profiles (Eco, Trail, Sport, Custom) on the fly, adjust phase current limits, configure variable regenerative braking, and monitor live metrics including speed, motor temperature, battery voltage, power draw in watts, and amp-hours consumed.

Installation & Auto-Detection: Installing the 12F utilizes direct-fit connectors. After securing the controller and connecting phase leads, run the automated Hall sensor angle detection routine via the display menus. Apply non-conductive thermal paste between the controller backplate and frame to maximize conductive cooling.

Companion Upgrades: Enhance your build with a primary belt drive conversion for silent operation, a 72V battery pack, and a 220mm oversized front rotor kit for balanced braking.

Frequently Asked Questions:

Q: Do I need a smartphone to configure the Nucular 12F controller? A: No. The included handlebar micro-display gives you complete access to power curves, speed limits, regen settings, and diagnostics without needing a phone.

Q: What makes FOC (Field-Oriented Control) superior to standard trapezoidal controllers? A: FOC feeds sinusoidal current into the motor synchronized with real-time rotor angle, eliminating motor hum, reducing heat, and providing buttery smooth low-speed throttle modulation.

Q: What is the maximum operating voltage of the Nucular 12F? A: The 12F supports battery configurations up to 20S (84V peak fully charged), compatible with 60V and 72V batteries.

Q: Does the Nucular kit support progressive regenerative braking? A: Yes. Variable regenerative braking can be configured to engage automatically upon throttle release or progressively via an electronic brake lever.

Q: How many riding profiles can be saved on the display? A: You can save up to four distinct riding profiles and switch between them instantly using the handlebar display buttons.

Sinusoidal Commutation & Vector Mathematics: The Nucular 12F uses 32-bit vector processing to calculate exact magnetic rotor angle at microsecond intervals. By delivering pure sinusoidal AC current into the motor phases, torque ripple is eliminated, resulting in completely silent operation and precise low-speed modulation.

Micro-Display Ergonomics & Sunlight Readability: The high-contrast color OLED micro-display is sealed in an aluminum housing with anti-reflective glass, providing clear visibility in direct desert sunlight. Weatherproof tactile buttons allow glove-friendly navigation through menu systems without taking your hands off the grip.
