The objective of the invention is a drive unit for a hoist, in particular for a hoist consisting of a motor 3, a gear 1, a brake 2, and a brake housing 8 serving as support, onto which the facing of the motor and/or the gear is flanged. The drive unit has a shaft 6, which simultaneously serves as a motor shaft and as a gear shaft, and the brake body 2 within the brake housing 8 is fastened to the shaft. Preferably, the motor 3 and/or the gear 1 are flanged, unsupported, to both sides of the brake housing 8.
