wound rotor motor: what is it? - motion control tips

Jul 17, 2017 · However, wound rotor motors are beneficial in applications with high inertial loads – such as large fans, pumps, and grinding mills – because the wound rotor design allows the load to be accelerated gradually through speed and torque control. And they can develop very high starting torque at standstill with low inrush current

inverter inrush current - page 1 - eevblog

Oct 30, 2011 · I wonder what would happen if you put a ~39uF 250VAC capacitor in series with the grinder. 39uF @ 50hz would limit the current to 2.8A (644W) I have no idea what sort of effect it would have on the grinder motor though. If the grinder started spinning you could then bypass the cap with a switch or relay+timer when it was up to speed. hehe, note the word "bypass", not "short out" 39uf @ …
