Joe,
I was referencing a previous post with the 16 kHz. At this and higher frequencies, the combined inductance and series resistance will produce a low pass filter that will serve to limit rise times and produce triangle waves instead of the the expected square waves. Glad to see you back on the forum.
Perhaps Richard, if you are reading this, can give us a handle on motor winding inductnce. I would think it would be pretty high, on the order of 100 mH. I won't be able to do any measurements for several days.
