No, on the contrary, I think one message explicitly allows the use of KOP motors as tachometers.

Question:

Are purchased DC tachometers allowed as sensors?

Is it legal to use a KOP motor as a DC tachometer rather than as a motor?

Answer:
a) Yes

b) Yes, if it is a KOP motor
While some reading the other message may (wrongly, I believe) infer that all motors may not be used a a tachometer. I think that it is in reference to using a (implied non-KOP) motor as a tachometer.

Question:
Are DC Tach Generators allowed as sensors?

If so, can DC motors be used as tach generators solely to provide a signal source to an analog input?

Answer:
DC Tach Generators are allowed as sensors.

DC Motors are not allowed per <R44>.

That is how I read the rules/Q&A anyway...
