This unit will help us demonstrate the characteristics of angle encoders in the application.

But first, a brief look at the design.

From 00:42

an inductive AMO encoder, and a magnetic ECM encoder.

From 01:06

The motor current, specifically the noise of the motor current is a criterion for the motor's attainable dynamic performance.

From 01:38

This optical encoder's noise band is very narrow and uniform under varying speed

From 02:39

The two encoders with a very narrow noise band are the optical encoders.

From 03:02

and performed a comparative accuracy measurement in accordance with ISO 230-2

From 04:37

To supplement ISO 230-2, we also performed a further measurement of dynamic performance

From 05:29

Once again, the optical encoders exhibit no speed-dependent error

From 06:16

So that was a basic summary of the demonstration showing the differences between the various encoders.
