Motor Controller Lineup

FOC motor controllers for every scale — from compact robot joints to high-voltage industrial actuators.

High Voltage & Modular

VESCAT HighVolt

Stacked modular architecture — Power Board + Controller Board

VESCAT HighVolt is a high-efficiency modular motor controller designed for high-voltage actuator systems. By operating at high voltage, it significantly reduces current draw and heat generation while achieving superior efficiency — enabling compact, thermally stable designs for demanding applications. Its two-layer stacked architecture separates the Power Board and Controller Board for maximum scalability, and built-in EtherCAT support enables real-time, high-speed communication for multi-axis industrial and robotic systems.

Software — AI-Powered

OpenRobot Motor Tool

Motor analyzer with AI-driven parameter auto-tuning

A comprehensive GUI tool for configuring, monitoring, and tuning OpenRobot motor controllers. Its core strength is AI-powered motor parameter tuning — the tool analyzes step responses and frequency characteristics via FFT, then leverages LLM (Large Language Model) to automatically recommend optimal PID parameters, eliminating the need for manual trial-and-error tuning.

CAN Control & Monitoring

Motor control (position/speed/torque), real-time data graphs, parameter read/write

AI Motor Parameter Tuning

LLM analyzes step response & FFT data to auto-recommend optimal PID gains — no manual tuning required

Firmware Management

Firmware and bootloader upload over CAN EID — no USB needed

CAN-Only Architecture

Designed exclusively for PCAN-USB communication. Auto-scans CAN bus, reads MCCONF/APPCONF on connection, and syncs pole pair from encoder ratio.

Real-time Visualization

Live graphs for RPM, current, voltage, temperature. Waveform sampling analysis and custom experiment data plotting (COMM_PLOT).

AI-Powered PID Optimization

Measures step response → computes settling time, overshoot, FFT quality score → AI recommends Kp/Ki/Kd/Kd Filter values. Iterative auto-tuning loop for position & speed control.

Tech Stack

Python 3.10+ / PyQt6 / pyqtgraph / NumPy / SciPy / OpenAI API. Windows with PCAN driver required.
