While many factors complicate this, the fact is that short wires between the
inverter and the motor (15 feet or less) and use of 230 volt (not 460 volt)
power makes the problem go away. Spikes stay below 1000 volts, which cheap
motors can withstand. Inverter grade motors are not needed if you keep to
those two rules.

YES, and too many don't realize the spike problem even exists.
