How to Drive a Motor with Single Resistance Sampling

[zhouqicheng]

Hello, do you have a motor drive routine for single resistance sampling? Or how to use the three-phase resistor program to change

Hi zhouqicheng,

The S32K motor control kits could be found on the web page http://nxp.com/AutoMCDevkits or directly Arm-based kits at http://nxp.com/S32KDevKits

Currently, the Single-shunt example software contains SW packages for MCSPTE1AK116, MCSPTE1AK144 kits, and MCSXTE2BK142 evaluation board. Look for "1Sh" in the project folder name.

Unfortunately, the Single-shunt example software for S32K3 is still in progress.

The same is valid for application notes for this version of the software example code - they are not publicly available yet. However, you may look at AN5327: 3-phase Sensorless Single-Shunt Current-Sensing PMSM Motor Control Kit with MagniV MC9S12ZVM. The current sensing and reconstruction technique is described in chapter 3.3.2 Phase currents reconstruction.
It is for different MCU, but the principle is the same.

I hope it helps you.

Bes regards

RadekS

Yes, sure. Here are the links:

MCSPTE1AK116 kit and direct link to the MCSPTE1AK116-SW

MCSPTE1AK144 kit and direct link to the MCSPTE1AK144-SW

MCSXTE2AK142 kit and direct link to the MCSXTE2AK142-SW

The nxp.com/AutoMcDevKits is an upper-level web page and above mentioned kits may be found under the Arm-based Development Solutions section.

Best regards
