Abstract
A centrifugal blower for an air conditioning system in a motor vehicle may include a centrifugal fan with an electric motor, which may drive a fan wheel in rotation. The centrifugal blower may also include a motor bracket for the electric motor, which may receive the centrifugal fan internally and may have a collar extending outward in a radial direction. An encircling water protection ring may be arranged internally on the collar, the water protection ring extending upward in an axial direction. The motor bracket may be configured as a hollow part with an interior annular water collection channel arranged beneath the collar, and may have a floor tilted radially outward. The at least one opening may be disposed at a transition from the collar to the water protection ring, by which water may drain into the water collection channel. The water collection channel may include at least one drain.
