Where Motor Performance Meets Programme Reliability
Configurable motor controllers built for long-term OEM deployment
BLDC Motor Controllers
LECO UMC-B Series
The LECO UMC-B series is LECO’s production-ready BLDC motor controller platform, deployed for industrial and defence-adjacent applications requiring high performance, stability, and long-term support.
Designed for OEM integration, the UMC-B series enables customers to deploy BLDC motor systems without reliance on imported, closed-firmware controllers.
