Document Type and Number:
WIPO Patent Application WO/2015/110618
Kind Code:
A3
Abstract:
The invention relates to a variable-speed machine gearbox unit comprising a variable-speed electric machine (R) having a stator (1) and a rotor (2) and a speed modulation planetary gearbox (P) comprising a sun gear (P1), a ring gear (P2) and a planetary carrier (PS), in which gearbox planetary gears (PP) that mesh with both the sun gear (P1) and the ring gear (P2) are rotatably mounted. The machine (R) and the gearbox (P) are coaxially arranged in a housing (4) and form a single structural unit. The rotor (2) is non-rotatably connected to the planetary carrier (PS) or the ring gear (P2) and is mounted by means of same.
