&gt; Any motor will need both a voltage and current to operate properly, and
they tend to draw more and more current as the source (inverter) voltage drops.<br>
<br>
<br>
Back to basic physics:<br>
<br>
Depending on design, electric motors can be constant power or constant torque
(or some combination of two) devices.<br>
<br>
Three phase AC motors are generally simpler in design and better behaved than
either either single phase AC motors or DC motors.&nbsp; Permanent magnet
synchronous 3 AC motors (available now) closely approach the theoretical
limits of electromechanical motor systems in general.<br>
<br>
Modern power electronics and control systems give us essentially perfect
control of voltage, current, and frequency in AC systems.<br>
<br>
Intelligently combining the above allows us to design efficient
electromechanical systems which match nearly any complex supply
impedance.&nbsp; These systems also happen to live longer, fail less often, and
reduce both battery bank and inverter requirements.<br>
<br>
The market (arguably free on so many levels, and obviously not on so many
others) can address this using current technology.&nbsp;&nbsp; System sizing
math not has changed fundamentally in several decades but we are getting closer
to those fundamental limits.<br>
<br>
Industrial systems are a bit ahead of the consumer market in some areas but
behind in others.&nbsp; As one very basic example, Turbocor's maglev compressor
has created a few waves in the commercial and light industrial sector but I
fully expect some fascinating trickle-down benefits over next few years &lt;<a
