So you get a page of label paper for your inkjet printer

make a nice little label that says:

Kens Kustom Analog Tachometer
Model 2006F
Serial # 123456789
(not a motor)

and put it on a DC motor and Wallah! you have a tachometer.

This rule is really splitting hairs and getting lost in semantics. If a device with coils and magnets is not wired to a power source, then it is not functioning as a motor.

This reminds me of a black-powder kit I got for christmas one year. When assembled it was a black-powder pistol. But you must have a pistol permit to own a pistol. According to the manual that came with the kit, if you assemble it, but never fire it, then its not a pistol and you dont need a permit

but the first time you put black powder and a bullet, and fire the thing, then it instantly transforms into a pistol, and a permit is now required!
