Can an Arduino mimic a motor commutator?

[qannon]

Thanks for the "switched reluctance motor" thought ,,, I researched a little on what Bill Gates and others had tried to accomplish, very similar in theory to what I am trying to do but they stuck with the three phase setup and did not opt in controlling each coil individually...

[qannon]

Thanks, even if it is a no at least I will quit looking at Arduino to supply the switching tasks, now I will be going the Raspberry Pi route, probably a good thing as my helper in this endeavor is fluent in Pi , too bad an Arduino consumes a lot less energy... Thanks again for providing me with the answer I was looking for,
Robert

The OP is probably trying to re-invent a switched reluctance motor. Gates and some other rich fools dumped millions of VC into some startup that claims their motors are 60% more efficient than current machines.

Well it seems to have worked. Unless I'm mistaken, that's the same as the IPM-SynRM motor (Internal Permanent Magnet - Synchronous Reluctance Motor) that Tesla are now putting in their cars.

The Tesla motor is nothing new, it’s prior art and has been used with inverters on a commercial basis for years. Don’t buy into the hype. Tesla is a joke of company, they’ll be a blip in history if and when EV’s become the norm.

In an IPM motor, the stator is bog standard, it Is the positioning of the interior magnets that allow for a significantly increased constant power range, exactly what you need for low speed, high torque and high speed, low torque applications in EV’s. A conventional PM machine doesn’t work because it has a very limited constant power range due to the constant flux created by the magnet location.

A switched reluctance motor is a totally different animal than an IPM motor.

@qannon

All that aside I believe @WattsThat answered my question , and its a no, an Arduino can’t handle the switching operation , it looks like a Raspberry Pi will be the next option

Beats me as to where I said that.

A 16 MHz pulse rate would represent 444,000 rev/sec with 36 individual poles being switched. Looking at it from a conventional viewpoint of 7200 rpm with 36 poles, that’s 4320 pulses per second. That’s a bit over 37,000 Arduino clock pulses per pole commutation period. You can do quite a bit of work in 37,000 clocks on a one instruction per clock RISC machine.

Not at all sure what the OP has in mind but it sure doesn’t look like it’s motor design.

Hi,

@qannon

No sir, none programming , that is for my “IT guy” friend for this "project, my electrical background is in commercial electricity single and three phase,

Then why isn't your "IT guy" asking the question, he would have an understanding of what controller processing power is needed.

Good Luck.. Tom....
