Motor Control

We design and develop fault-tolerant, hot-redundant motor drivers for space mechanisms that must keep moving—robotic arms, gimbals, stages, and actuators. Our modular HW/SW architecture is aligned with ECSS verification standards, ensuring compliance, reliability, and scalability for space-grade systems.

Capabilities

Continuous operation under a single internal fault (sensors & power stage) with hot-swap recovery.
Advanced control: FOC as primary (with DTC/trapezoidal options), fast inner current loop, PWM.
Flexible topology: 3/5/N phase motors; configurable 12/24/48 V classes.
Sensor strategy with redundancy: encoder/resolver/Hall support plus sensorless fallback (e.g., back EMF) to maintain torque/speed/position control.
Autonomous diagnostics & thermal management: early fault detection, isolation, recovery, motor/driver thermal protection.
Robust interfaces: dual power bus capability (28 V/56 V classes), LCL with overcurrent protection, regenerative energy handling, CAN telecommand/telemetry.
Safe braking: controlled stop and fail-safe behaviors.

Applications

Robotic manipulation, solar array modules, sampling mechanisms, pointing/guidance gimbals, precision stages—any motion system that cannot tolerate downtime.
