INFINITY-JOINT · PLATFORM · BI-STABLE MAGNETIC ACTUATION
The held position costs zero power.
INFINITY-JOINT is Reinventy's platform for bi-stable magnetic actuation with zero-energy holding. Conventional electric actuators draw continuous power to maintain a held position against external loads; INFINITY-JOINT does not. The magnetic flux is switched between latched low-reluctance paths rather than continuously generated — the held position is sustained by permanent magnets in a stable magnetic configuration, and coil energization is required only for the brief transition pulses between stable states. The platform addresses endurance-critical actuation problems where conventional actuators are limited by continuous power consumption, thermal accumulation, or position drift.
THE THESIS
Hold the position. Without holding the power.
The energy economics of actuation are dominated by the static phase. In most operating profiles — orbital manipulators waiting on target, autonomous logistics robots in pause states, industrial manipulators holding workpiece position during processing — the actuator spends the majority of its operating life NOT moving. Yet conventional electric actuators draw current throughout that static phase, dissipating power as heat and accumulating thermal load on the bearing assembly, the winding insulation, and the surrounding mechanical structure. The longer the hold, the greater the energy cost and the greater the deviation from the commanded position as thermal expansion shifts the actuator geometry.
INFINITY-JOINT is engineered to break that energy-static-phase coupling. The platform uses bi-stable magnetic latching — two stable magnetic configurations, with the held position sustained by permanent magnets in the latched configuration. The magnetic flux is switched between configurations via PPMT (Parallel Path Magnetic Technology) flux shunting; the coils energize only for the millisecond-scale transition pulses between stable states, then de-energize once the new configuration is latched. The deterministic control of when and how those transition pulses fire is provided by Mag-FOC. Static power draw is zero. Static thermal rise is zero. Position retention is independent of hold duration.
ARCHITECTURAL FOUNDATION
Built on PPMT and Mag-FOC.
INFINITY-JOINT integrates two Reinventy technologies that together enable the zero-energy holding paradigm:
- PPMT
Parallel Path Magnetic Technology. The flux-switching architecture that allows the magnetic flux to be redirected between low-reluctance paths (latched configurations) via brief steering pulses, rather than being continuously generated against a high-reluctance gap. PPMT makes bi-stable magnetic latching practical at the torque levels relevant to platform-scale actuators.
View → - MAG-FOC
The deterministic control surface for transition events. Mag-FOC fires the millisecond-scale steering pulses that move the platform between latched configurations, with the precision and repeatability required for closed-loop position control at the platform level. The same control primitive that anchors Reinventy's other electric propulsion platforms underlies the transition control logic of INFINITY-JOINT.

OPERATING CHARACTERISTICS
Three properties that define the platform.
INFINITY-JOINT is characterized by three operating properties that distinguish the platform from conventional electric actuators:
- ZERO-POWER STATIC PHASE
During the static phase — when the platform is holding a position against external loads — no continuous coil energization is required. The held position is sustained by permanent magnets in the latched configuration. Static power draw to the actuator stage is removed as a continuous operational cost.
- MILLISECOND TRANSITION PULSES
Transition between stable configurations is performed via brief steering pulses on the coils, on the millisecond scale. The pulses are deterministically controlled by Mag-FOC, with the precision and repeatability that closed-loop position control at the platform level requires. Energy expenditure is bounded by the transition events, not by the hold duration.
- POSITION RETENTION WITHOUT DRIFT
Because the held position is sustained mechanically by the latched magnetic configuration rather than by continuous current, position retention is independent of hold duration. Conventional thermal-drift coupling — winding heat causing rotor expansion causing position deviation — does not arise in the static phase.
Specific values for transition pulse duration, energy expenditure per transition, hold torque, and position retention precision are released under non-disclosure agreement.
APPLICATION CLASSES
Orbital. Logistics. Endurance-critical industrial.
INFINITY-JOINT is configured for application classes where the energy cost of the actuator static phase is a primary operational constraint:
- ORBITAL MANIPULATORS
Orbital manipulator applications — the held-position economics of orbital robotics impose energy budgets where continuous-power actuator hold is a system-level constraint. INFINITY-JOINT addresses the static-phase energy cost integrally, releasing the energy budget for the operational manipulator cycle. Aerospace prime contractors and space robotics programs are the primary engagement audience for this application class.
- AUTONOMOUS LOGISTICS ROBOTICS
Autonomous logistics robotics — package handling, warehouse robotics, and mobile manipulation systems spend significant duty-cycle fraction in pause/hold states between active motion. The duty-cycle energy savings of zero-power static phase translate to extended operational range per battery cycle and reduced thermal management overhead at the actuator stage. Industrial robotics integrators and autonomous logistics OEMs are the primary engagement audience.
- ENDURANCE-CRITICAL INDUSTRIAL MANIPULATOR HOLD
Industrial manipulator applications where the platform must hold a workpiece, tool, or fixture in position for extended duration (machining cycles, assembly station hold, processing line dwell). The cumulative energy and thermal cost of conventional continuous-power hold drives both the operating expense and the maintenance interval of the actuator. INFINITY-JOINT removes that cost structurally.
