TMCS1126: Ripple Current measurement

Tom Nie

Part Number: TMCS1126

Tool/software:

If I have a close-loop controller with a dc motor using Ripple Current for position/counts and would like to measure the counts external from this system do you have a recommendation?

Hello Tom,

Thank you for your post.

I am most familiar with the magnetic sensing for motor encoding.

Have you taken a look at this reference design? Abs. Angle Encoder Ref. Des. W/ Hall-Effect Sensors for Precise Motor Pos. Cont. (ti.com)

Here is also a link to a higher-level presentation on using hall-effect sensors for this: using_hall_effect_position_sensors_for_rotary_encoding_applications.pdf

I hope these help,

Joe
