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...
