houssam Posted December 30, 2010 Report Share Posted December 30, 2010 At sites, we use double cage external lift hoist, single and double speed, with countre weight and without CW. The starting DOL current for sigle cabin hoit is 163 A ( three motors on a rack. each is 11 KW). We use a generator 250 KVA ( 200 KW ). The question is : How to minimize this starting current. so we can use a generator with less capacity. Lift Hoist brand is GJJ - China. Do a ciecuit Star - Delta with 2 sec switiching wll be enough? or Do an inverter will be good regardless of the cost? Link to comment Share on other sites More sharing options...
