NTMicroDrive: ASIL A ready Software Stack for Micronas Embedded Motor Controllers

 

The NTMicroDrive, an ASIL A ready Software Stack that permits the direct control of brush-type, stepper, or brushless motors (up to 10 watt) with the use of Micronas HVC4223F.

NTMicroDrive is a production-ready and highly flexible, paramaterizable firmware with sophisticated communication, monitoring and power management functions as well as a configuration 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 sensorless control, as well as various stepper configurations.
