* IV version
Impregnated coil through dip-coating using epoxy transparent paint (standard stator coil dip-coating process).
* IM version
Impregnated coil through dip-coating using transparent epoxy paint with silicone applied on contacts at the end of winding, three-pole wire and coil covered by a nylon cap. The coil is not drowned in the resin but visible; caution should be paid when mounting the motor so that the cap open part faces downward to prevent its filling up with condensate.
* INC version
Coil with IP55 protection, the coil is completely drowned into the epoxy resin.
