Taurus AEX

The Taurus AEX from allocortech is a compact, high-efficiency BLDC motor controller engineered for precision actuation and propulsion in professional unmanned systems. It incorporates full four-quadrant Field Oriented Control (FOC) with Space Vector Pulse Width Modulation (SVPWM) to enable smooth, responsive motor performance up to 2 kW peak power. Designed for versatility, the controller supports both Hall and Quadrature encoders, providing enhanced positional awareness for propulsion, linear actuation, or servo control tasks. With isolated CAN 2.0 and RS-485 communication interfaces, Taurus AEX integrates easily into complex multi-node control architectures and ensures robust, noise-immune data exchange.

Built for demanding operations, the Taurus AEX achieves exceptional electrical efficiency across its nominal range and supports overmodulation to extract maximum motor output. The software foundation, developed on the allocore SDK, allows customization of control algorithms, communication protocols, and operational modes to meet unique system requirements. Four-quadrant regenerative control supports braking and hybrid generation modes for energy-efficient operation across a range of mission profiles.
