NTMicroDrive

The complete package for Micronas Embedded Motor Controller

NTMicroDrive Safety Software

ASIL A Ready Software Stack for Micronas Embedded Motor Controllers

NTMicroDrive 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
