Unleash the full potential of your PMSM & BLDC motors.
VDriveMotion is a premium sensorless field oriented control (FOC) controller optimized for advanced robotic motor control. By combining high-speed 3-phase current measurement with state-of-the-art magnetic saliency tracking, it delivers precise servo motor control for both BLDC and PMSM systems without requiring physical encoders.
Designed for High-Performance Servo Motor Control
Everything you need to drive complex robotic systems reliably.
True Sensorless FOC
Experience precise sensorless field oriented control without bulky encoders or hall sensors. This system maintains full nominal torque even at absolute zero speed, eliminating complex mechanical feedback wiring, reducing failure points, and optimizing space in advanced robotic actuators.
Advanced PMSM & BLDC Observation
Utilizing precise 3-phase current measurement combined with state-of-the-art magnetic saliency tracking and flux observers. The state observer dynamically calculates the exact rotor position under heavy loads for both PMSM (Permanent Magnet Synchronous Motors) and high-pole BLDC motors.
Versatile Servo Motor Control
Perfectly adapt this FOC controller to any operational requirement with seamless switching between Velocity, Torque, and Position loops. Receive high-speed commands via CAN-FD or UART, and close the position loop locally for smooth, coordinated movements in multi-axis robotic arms.
High Power BLDC Driver Output
Engineered for extreme performance, easily handling up to 60A of peak phase current and 70V maximum input voltage. A robust direct-thermal PCB layout, paired with an integrated aluminum heatsink plate, guarantees stable power delivery under high continuous loads.
Zero-Speed Saliency Tracking
In standard sensorless FOC, the motor must be spinning to generate Back-EMF for the controller to estimate rotor position. At zero or low speeds, Back-EMF drops to zero, rendering standard controllers blind.
VDriveMotion solves this by utilizing high-frequency signal injection (HFSI). By injecting high-frequency voltage into the windings, the controller dynamically maps the rotor's magnetic saliency (inductance variations). This provides full sensorless torque control at absolute zero speed—giving you the performance of a physical encoder without the hardware cost or weight, ideal for demanding robotic start-up and holding applications.
- Signal Injection: We continuously inject high-frequency voltage into the motor phases (Vhf).
- Ripple Analysis: As the rotor shifts, its inductance variation dynamically modulates the resulting high-frequency current ripple (Ihf).
- Advanced Flux Observers: Real-time processing extracts these inductance variations to calculate the exact rotor position (θest) with zero hardware encoders.
- Silent Operation: Advanced control frequencies and ultra-smooth phase currents guarantee completely silent running.
