Hello all,
I wish to know what information can be determined by driving a DC motor with a sine wave (no DC offset) for testing?
I would expect, that the motor would go in one direction on the positive peaks then reverse to the other direction once the sine when into the negative, and so on.
The frequency of this sine could be varied, effects observed, what would this tell me?
How about once the motor is connected into the gear system and is now under load?
