Advanced Motor Drive Sensing (AMDS)

Advanced motor drives often require a lot of sensors. Cue the AMDS.

Introduction

AMDS stands for Advanced Motor Drive Sensing.

The AMDS is a complete embedded platform which is designed for motor drive sensing. It features a modular slotted design which makes it flexible and adaptable for the research environment. The platform PCBs include: (i) mainboard with slots, and (ii) three distinct sensor card designs aimed specifically for motor drive sensing.

The AMDS includes a dedicated MCU which samples up to 8 sensor cards which are installed in its slots. The user can implement custom filters in the MCU, such as low-pass or high-pass. A robust differential digital link is used to send sampled data to the host device.

AMDS + AMDC

The AMDS is designed to work directly with the GPIO expansion ports of the AMDC. However, it is a complete system which could be interfaced to any other host device, assuming the correct drivers are implemented in the host firmware.
