Overview

Sigma Muse (stylized as MUSE) is a machine room less elevator model that was produced by South Korean elevator manufacturer Sigma (a subsidiary of Otis Elevator Korea) between the 2000s and 2012. It was discontinued in 2012 and succeeded by the Sigma Muse NV which is basically an improvement of this model.

It is a machine room less model based on the Otis Gen2 model, using the same coated steel belts (as opposed to conventional steel ropes) and gearless motor as the Gen2. In other words, it is a rebadged Otis Gen2 model sold under the Sigma name for overseas markets. It was produced at the Changwon factory in South Korea. Muse was one of Sigma's two machine room less models sold at that time, other than the Sigma Solon which used conventional steel ropes.

In Indonesia, Muse is an extremely rare model and so far only one installation has been found.
