In one aspect, a shutter assembly includes a shutter frame and a plurality of louvers supported by the frame. The shutter assembly also includes a louver drive assembly and a motor positioned within the frame. The motor is configured to rotationally drive a drive shaft extending within the frame. Additionally, the shutter assembly includes a clutch assembly rotationally coupled between the drive shaft and the louver drive assembly. The clutch assembly is configured to disengage or decouple the drive shaft from the louver drive assembly when a torque transmitted through the clutch assembly exceeds a given torque threshold.

Motorized shutter assembly

A blind is arranged such that minimal force is required to rotate the tilt drum to tilt the slats from the fully open to the fully closed position and back, with each of the front and rear tilt cables sharing the load nearly equally throughout the entire path from the fully open to the fully closed position and back.
