Abstract
Presently elevator industry meets the big change to machine-room-less. We developed a ultra thin thickness lift machine, which used the RV reduction unit and flat motor. This Lift machine (passenger weight is 1ton) thickness is 200mm. And weight is only 270kg. It can be installed in almost gap between car and wall. And control is very easy. We think this machine will be the next machine instead of DD type and we hope to contribute to elevator industry with it.
