At LECO Controls, we build embedded controllers that master complexity and deliver reliability in real-world machines. Our strength lies in combining advanced control technology with a structured process, ensuring every controller — whether for motors, power systems, or specialized actuation — is validated, rugged, and production-ready.
Our Approach
From Physics to Products
Control Strategies Tailored to Physics
-
LUT-Based Control (for Magnet-Free Motors):
Instead of approximating non-linear flux with equations, we create a high-resolution “digital DNA” map of each motor. Our Look-Up Table (LUT) approach ensures instant torque vector selection for SynRel and SRM motors, eliminating ripple and inefficiency. -
Advanced Field-Oriented Control (for PM Motors):
For Axial Flux, BLDC, and PMSM, we implement model-based FOC with high-speed loops (>100 kHz), flux-weakening algorithms, and precision PWM schemes. The result is smooth torque, wide speed range, and mission-critical responsiveness.
