I noticed doctorbass has been largely absent as well, though that could just be a coincidence.

Re: What's so bad about low impedence?

Generally, with motors, you want to get power OUT of the load (the motor.) If power goes into a motor, but nothing comes out, it would be pretty useless, eh? power in, torque & rpm out is what you want. nice try cya tho. no, the load ohms is dictated by impedance matching . . .Maximum Power Transfe...

Re: What's so bad about low impedence?

It all goes back to supply voltage. The power you can get out of a load is given by its resistance (at DC) or its impedance (at AC.) well there's the flaw in your thinking. generally power goes into a load. hard to believe you actually went to MIT. interestingly lower supply voltage also comes back...

Re: What's so bad about low impedence?

Then transistors came along, ... what i said in a broader sense to include more than transistors. You can't have a motor with no impedance of any kind. no but you can (theoretically) approach it. You'd violate the laws of thermodynamics. which is why i asked ... i'd really like to know what sort of...

Short answer, the current and speed control algorithms on ASI are not designed for motors with extremely fast current ramp times (low inductance).
even shorter answer: slew rate
i think that's why LFP favours lower voltage/low turn count

Re: What's so bad about low impedence?

But they are talking about impedance, not resistance. Two different things. are they really? or is resistance along with reactance the two sides of the same impedance coin? When a circuit is driven with direct current (DC), there is no distinction between impedance and resistance; the latter can be...

well, zero ohms is ideal. so naturally a controller/inverter manufacturer is gonna say that, it's hard on the equipment. it makes his job more difficult to design as well as for more warranty claims having to drive/transfer power into lo-ohms. why do you think speaker impedance keeps getting lower. ...
