PCB Stator Technology

Revolutionary Motor Design, Tailored for Precision

Read More

At the heart of Torq Head’s groundbreaking performance is its use of advanced PCB stator motor architecture — a radical departure from traditional iron-core motor construction. Designed from the ground up using generative algorithms, each motor is purpose-built for Torq Head's unique form factor and payload requirements.

While the PCB stator concept itself is not proprietary, Torq Head features multiple patented innovations surrounding the use, control strategy, and integration of this technology within remote head systems.

  • Zero Cogging: Flawlessly smooth motion with no mechanical resistance.
  • Ultra-Low Inductance: Instantaneous torque response with no perceptible lag.
  • Form Factor Freedom: A flat, lightweight design enables tighter system integration.

Whether deployed on a tracking vehicle, robotic platform, gimbal system, or unmanned asset, Torq Head’s motor system redefines what's possible in modular stabilization and motion control — offering unparalleled performance in a compact, responsive, and silent package.

Absolute Encoders

Absolute Encoders & Internal Indexing

Precision Awareness with No Calibration Required

Read More

Each Torq Head motor features a high-resolution absolute encoder with over 1 million points of reference, combined with an internal index mark that ensures the system always knows its exact position — instantly and persistently.

Unlike traditional motors that require homing on startup or suffer from positional drift, the Torq Head’s encoders provide real-time spatial awareness without the need for recalibration or initialization routines.

  • Instant Boot-Up Accuracy: No need for zeroing or homing sequences.
  • True Absolute Positioning: Each axis knows where it is at all times, even after a power cycle.
  • Reliable Reference in Motion: Keeps positional integrity under heavy dynamic loads and disturbances.

This system is especially advantageous in environments where downtime, complexity, or recalibration are unacceptable — ensuring precise motion control from the moment power is applied.

No Cogging

Perfectly Smooth Motion Without Magnetic Detents

Read More

Traditional brushless motors wrap copper wire around iron cores — a manual, imprecise process that results in unequal torque distribution and mechanical “detents” in the magnetic field. These imperfections produce a gear-like cogging effect that stabilization software must constantly correct for.

Torq Head’s PCB stator motors eliminate this problem entirely. With no iron cores and precisely balanced magnetic fields, the motors generate zero cogging — resulting in:

  • Smoother Motion: No resistance “steps” as the motor rotates.
  • Better Stabilization: No detuning or baked-in compensation needed.
  • Natural Feel: Motors can gently hold position without snapping or jerking.

This allows for much more responsive, precise movement and cleaner tuning — giving operators and control systems the confidence to work without compromise.

Tremendous Torque Response & Motor Efficiency

Instant Reaction, Smarter Power Delivery

Read More

Traditional brushless motors often struggle with slow current response, which limits their ability to respond quickly to dynamic stabilization commands. This delay can compromise smoothness and tracking performance — especially with unpredictable motion or large payloads.

Torq Head’s MAX motors are engineered for high-efficiency, high-response torque output. Thanks to ultra-low inductance and tight integration with our control algorithms, the motors deliver real-time torque corrections without delay.

  • Immediate Motor Response: Commands are translated into motion with no perceptible lag.
  • Efficient Power Use: Reduced overshoot and energy waste during correction cycles.
  • High-Fidelity Control: Maintains precise behavior under changing loads or inertia profiles.

Whether you're stabilizing handheld footage or tracking high-speed motion, MAX motors allow the Torq Head to respond instantly and smoothly — without compromise.

Lightweight Design

Lightweight & Integrated Design

Optimized Power-to-Weight Efficiency

Read More

MAX motors eliminate bulky iron cores and oversized housings. Each motor is custom-sized for its specific axis and torque requirement, reducing unnecessary mass while maximizing performance.

  • Precision-Fit Motors: No catalog components or overbuilt designs.
  • Structural Integration: Motors are part of the chassis, not bolted onto it.
  • Fewer Parts, Less Weight: Milled housing and shared components simplify the system and reduce failure points.

This makes the Torq Head lighter, stronger, and easier to deploy across any platform or application.

Payload Strength

Payload Strength

Big Support from a Small System

Weighing just under 18 lbs, the Torq Head can stabilize payloads up to 65 lbs without compromise. This strength-to-weight ratio makes it ideal for both heavy camera packages and rugged industrial sensors.

Modular Design

Flexible, Modular Design

3 Motors. Infinite Configurations.

Read More

Torq Head isn't a single-purpose remote head — it's a modular ecosystem built around a set of intelligent motors. Whether you're building a handheld rig, a vehicle mount, or a 3-axis stabilized platform, you can configure the system exactly to your needs using the same core hardware.

  • Adaptable Layouts: Use 1, 2, or 3 motors depending on your project.
  • Component-Based: Motors and cradles can be reassembled for custom rigs.
  • Fewer Limitations: One investment scales across multiple platforms and form factors.

This modularity reduces cost, increases flexibility, and makes Torq Head a future-proof motion control solution.

Field Serviceable

Field Serviceable Components

Quick Maintenance, Minimal Downtime

Read More

The modular design makes it easy to swap motors and service components on-site without sending the whole head in for repair. Common failures can be diagnosed and fixed by operators in the field.

  • Swappable Motors: Replace only the axis you need.
  • Accessible Internals: Inspect or service components quickly.
  • Service Without Shipping: Keep your system on set and working.
IMU Placement

Intelligent IMU Integration

World-Aware, Not Payload-Bound

Read More

Thanks to absolute encoders and zero-cogging motion, IMUs no longer need to be mounted on the payload itself. This allows clean builds and 360° freedom without tethering the cradle.

  • No Payload Wiring: IMU does not need to ride with the camera.
  • Global Orientation: Tracks its position in world space, not just relative motion.
  • Cleaner Builds: No loop cables or roll axis blocks.
Stabilization Control System

Intelligent In Motor Stabilization™

Smarter Stabilization Architecture with Nested Reciprocal PID Loops

Read More

At the core of our Intelligent In Motor Stabilization™ technology is a patented control architecture that goes beyond traditional feedback loops. Instead of relying on a single PID controller, Torq Head employs a nested reciprocal PID loop system — allowing separate control of torque, speed, and position across different timescales.

This layered control approach results in faster corrections, better damping, and more reliable performance across a range of motion profiles, payloads, and environmental disturbances.

  • Nested PID Structure: Inner loops handle motor speed and torque; outer loops focus on position and stability.
  • Reduced Oscillation: Better suppression of jitter, overcorrection, and vibration.
  • Precise Control: High-fidelity stabilization under variable inertia or directional changes.

Intelligent In Motor Stabilization™ allows the Torq Head to respond naturally and immediately — without lag, instability, or excessive tuning — giving you true confidence under pressure.
