The Challenge
Legacy motors are oversized for their output. Gearboxes add weight, cost, and additional failure points to every installation.
No graceful degradation — when one phase is lost, the entire motor shuts down. Every failure becomes a full-system event.
45% of global electricity powers motors,1 yet century-old topologies have plateaued. Incremental gains can't close the gap.
Linear Labs built a new motor class from the ground up to solve all three.

Our Technology
A patented circumferential flux architecture purpose-designed for the highest torque density in any motor class — delivering breakthrough efficiency and fault tolerance in a compact package.
Purpose-designed from the ground up for maximum torque density — the first fundamental advancement in motor architecture in over 100 years.
How It Works
The HET (Hunstable Electric Turbine) is a patented 4-rotor permanent magnet architecture purpose-designed for the highest torque output in its class. It combines axial and radial flux paths into a single circumferential flux tunnel — extracting more torque per kilogram than any conventional motor topology.
Unlike legacy radial-flux machines limited by a single flux path, the HET's multi-axis approach creates the equivalent of three motors working in concert — maximizing flux linkage while minimizing copper losses.
*2× torque density, 50% weight reduction, and 97% peak efficiency based on Linear Labs internal testing of HET prototypes vs. equivalent-rated radial-flux motors, air-cooled at rated operating point.

Case Study
The PitchPro 2000 system was installed at Lamar Light & Power in Q1 2026, replacing the legacy hydraulic pitch system on a GE 1.5 MW turbine. The drop-in retrofit was completed with zero structural modifications. Operational data confirmed the system's performance across a full range of wind conditions, validating efficiency, response time, and reliability targets.
High-torque, high-efficiency motor systems engineered for the most demanding applications.
Energy
From pitch systems on aging wind fleets to downhole drilling motors and grid-scale energy storage, the HET architecture delivers the torque density and fault tolerance that energy applications demand. Our PitchPro 2000 is already modernizing the GE 1.5 fleet.
Industrial
Industrial motors drive 45% of global electricity consumption.1 The HET's 2× torque density means smaller, lighter motors that eliminate gearboxes in pump drives, linear actuators, and compressor systems — reducing both footprint and maintenance burden.

Nuclear
Our CTO has direct experience with 79 of 119 US nuclear plants. The HET's fault tolerance and multi-phase ride-through make it uniquely suited for safety-critical nuclear applications, from small modular reactor coolant pumps to containment system actuators.
Defense
50% lighter motors mean reduced platform weight for military vehicles and naval propulsion. Built-in fault tolerance ensures mission continuity — the HET degrades gracefully rather than shutting down, a critical advantage in theater.
Mining
Mining demands maximum torque in minimum space. The HET's direct-drive capability eliminates the gearbox entirely — removing the most common failure point in conveyor drives and haul truck propulsion systems while reducing maintenance windows.
