NTMicroDrive

The complete package for Micronas Embedded Motor Controller


NTMicroDrive Safety Software

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.

NTMicroDrive Enterprise-Board

HVC 4223F based Embedded Motor Control

The NTMicroDrive Enterprise-Board is a development and production ready platform that permits the direct control of brush-type, stepper or brushless motors (up to 25 watt). The motor control is empowered by the TDK Micronas HVC 4223F Motor Controller. Next to the motor driver part is an USB/LIN-Adapter for rapid prototyping. Both parts can be separated and used independently.
For commercial applications the NTMicroDrive Software Stack together with the HVC 4223F Motor controller provides a ready-to-use solution.

Customer Benefits

  • The NTMicroDrive Enterprise-Board provides a complete, high-quality design environment for motor applications.
  • Usable for the different types   of motors, only with parameter  change.
  • The development kit helps to simplify the design process and reduce time to market.

Typical applications

Control of Stepper, brush-type and brushless (BLDC) motors up to 25 watt, e. g.

  • Grill shutter (BLDC)
  • Fan flap / HVAC (Stepper)
  • Adaptive front light (Stepper)
  • Glove compartment (BLDC)
  • Fans (BLDC)
  • Small robotic (BLDC, Stepper)
  • Medical/orthopedics assistance (BLDC/Stepper)
  • Smart Home and Living
