NTMicroDrive

ASIL A Ready Software Stack for Micronas Embedded Motor Controllers


NTMicroDrive, an ASIL A ready software stack that permits the direct control of brush-type (DC), stepper, or brushless motors (BLDC) with the use of Micronas HVC 4223F. NTMicroDrive is a production-ready and highly flexible, customizable firmware with sophisticated communications, monitoring and power management functions as well as a configuration software tool. The software stack allows complex motor control algorithms such as Space Vector Modulation (SVM) for permanent magnet synchronous motors (PMSM), six-step commutation with sensor feedback or without sensor control, as well as various stepper configurations.
