ALL power measurements performed using an oscilloscope with AxB capability, must use DC coupling in order to guarantee a true measurement of power, whether it be input or output power.

When the power supply is in CC mode the terminal voltage across the motor varies directly as the generator voltage.  If the motor spins fast enough in a direction where the BEMF opposes the power supply, then the power supply will drop out of CC mode and go into CV mode.  If the motor is spun fast enough that the generator voltage exceeds the power supply CV setting, then what happens depends on whether the supply is a one quadrant or two quadrant device.

Markymark,

There is no GENERATOR VOLTAGE. It's a reluctance motor: there is no rotor coil or brushes or magnets! It has an asymmetric rotor made of iron laminations and uses the same stator as a series-wound motor. Did you catch all that? Thus the effect I wrote about, and you poorly understood, is indeed related to the RELUCTANCE changing in time... Geez man, are you really that dense and are you seriously debating this very basic and well documented point? It involves parametric variation of inductance and is just the rearrangement of L*di/dt and there is no mutual induction. Get your facts straight, lest you make yourself look more like a fool.

Sorry but you are wrong.  SRMs act like generators and have been employed as such.  See for example:  http://www.engr.uky.edu/~radun/ResearchInfo/SRgenerators.doc

Markie,

Once again you have  misread everything I've written.

Synchronous reluctance motors were NOT what I described, nor did I ever bring them up. You continue to debate on things you do not understand. I gave a very clear and concise description of what my "reluctance motor" was (note the lack of the synchronous adjective). Reluctance motors do not posses generator action, as they cannot induce mutual induction by rotation. And for your information, I've actually built one, probably why I actually understand how they work and you don't. I take it you have very little experience in actual experiment and real life engagement with other humans involving technical topics. I honestly feel bad for any human who would have to work with you on an engineering project.

For your consideration is my own home made reluctance motor, which exhibits all the properties, both electrically and physically, that I've stated over the last few posts, which you feel is some how "wrong."
