6 Pole operation on the MMM - Long term effects?

We have successfully run 14 pole motors over 60,000 RPM on the MMM software without significant timing changes, and the MOSFET switching times on the MMM are in the order of 70ns -- so there will be NO ISSUE running higher pole count motors on the MMM.

The MMM uses a very high processing power microprocessor (25 MIPS) -- more than 4 times faster than competing ESCs. We also have the fastest timing calculations and loops in the industry -- often faster than competitors by an order of magnitude or more.

So the MMM will run high pole count motors better than anything else on the market. And it will keep timing tighter and efficiency higher than any other ESC, especially at high RPMs and power levels.

That's nice to know Patrick. Too bad my Big Maxx didn't like the MMM though, bad commutation according to Plettenberg.

Weird, plett and neu construction are not much (if any) different... And the MMM seems to work well wwith a neu.

I have heard that Plett will blame everything other than their motors when a warranty or repair claim comes up...

I know for a fact that the MMM works beautifully with Plettys... So the issue wasn't "bad commutation"...
