Is there a difference between inverter duty motors and inverter capable motors?

RE: Inverter Duty Motors
1. the increased stress on the insulation because of high voltage transients (as a result of fast pulse rises times giving reflections at either end of the cable) - mitigated by using special enamel coatings for the winding etc.
2. possibility of bearing currents - mitigated by insulated bearings etc.
3. increased losses in the machine primarily due to current harmonics - mitigated by reducing the rating compared to a motor working direct on line.
You could say that a inverter-capable motor need only deal with 1. and 2., whilst the inverter-duty motor deals with all three.

Be careful. The marketing people are running amok on these terms.
