A true pancake ambition.
A less-than-20 mm axial envelope is the design target for the motor architecture. Stator, rotor, feedback, bearing stack, connectors, and onboard electronics must be reconciled in the final assembly envelope.

REFERENCE DESIGN / PRELIMINARY TARGETS
Performance, simultaneous torque–speed capability, duty cycle, cooling, temperature cycling, environmental qualification, supply-chain origin, and safety functionality require validation. MIL-STD-810 ruggedization and U.S. manufacturing are program objectives. Slotless construction removes tooth-related cogging; energized torque ripple, system hysteresis, backdrivability, and pointing accuracy depend on the complete assembly and controls. Titanium corrosion resistance and thermal expansion compatibility must be assessed for the actual materials and environment.
01 / THE MOTOR PLATFORMIN DEVELOPMENT
Less mechanism.
More possibility.
Premium motors. Top-of-the-line integration.
We are developing a premium, ultra-shallow, slotless BLDC platform that couples the motor directly to the load. Mechanical packaging, windings, controls, sensing, thermal interfaces, and connectors are tailored to the application—from a compact optical payload to a precision robotic joint.
<20mm
Axial envelope target
A shallow architecture for space-constrained payloads and mechanisms.
Directdrive
No gear train in the motion path
Eliminating the gearbox removes its contribution to backlash and hysteresis.
SlotlessBLDC
Designed around smooth motion
A toothless stator architecture to eliminate tooth-related magnetic cogging.
Development targets are subject to prototype validation. System accuracy and energized torque ripple depend on feedback, controls, bearings, thermal conditions, and load integration.
MECHANICAL ARCHITECTURE / DEVELOPMENT CONSIDERATIONSDESIGN CONCEPT
Shallow by design.
Integrated by intent.
The housing, rotor, bearings, feedback, and customer mounting structure must work as one mechanical system.
Thin-wall titanium concept.
Grade 5 titanium (Ti-6Al-4V) is a proposed housing material. Wall thickness, stiffness, mass, machinability, corrosion exposure, and thermal expansion will be evaluated for the actual geometry and materials stack.
A direct path to the load.
Removing the gearbox removes gear-mesh backlash. Bearing friction, preload, structural compliance, alignment, and seals still govern reversal behavior and backdrive torque at the system level.
Slotless motion architecture.
A toothless stator with a supported copper winding ring targets elimination of tooth-related cogging. Energized torque ripple and positioning accuracy require characterization of the complete motor, feedback, and controller.
Conduct heat to the structure.
The thermal concept combines boron-nitride-filled potting with expanded natural graphite foil or OFHC copper interfaces. Heat rejection into the customer’s structure depends on contact resistance, geometry, cooling, and duty cycle.
Validate the complete load path.
Shock and vibration evaluation must cover bearings, rotor retention, magnet bonding, housing stiffness, PCB support, and air-gap clearance. Eliminating gears does not by itself establish shock survival or qualification.
Material selection, wall thickness, environmental temperature range, shock limits, and complete integrated dimensions are not yet validated. No infinite resolution, zero system hysteresis, or guaranteed pointing accuracy is claimed.
03 / ENGINEERING THE DIFFERENCEELECTROMAGNETICS → THERMAL → INTEGRATION
Every millimeter
has a purpose.
A motor architecture designed as a system, from the magnetic circuit to the path heat takes out.
Direct connection.
Fewer compromises.
Coupling the rotor directly to the load removes the gear reduction stage. Positioning performance will be evaluated at the complete assembly level, including feedback and control.
Smooth by
architecture.
Slotless winding development targets low-cogging motion for sensitive tracking and tactile applications. Torque output, ripple, and thermal limits will be characterized through testing.
A deliberate
path for heat.
Our proposed thermal stack explores boron-nitride-filled PCB encapsulation, expanded natural graphite interfaces, and a thin-wall titanium chassis. Materials and performance remain under evaluation.
