Patent number: 9677332Abstract: An actuator drive, for blinds, roller shutters and the like, has a drive motor and a centrifugal brake. A rotational disk is coupled to a drive shaft of the drive motor via a shaft flange. Two centrifugal shoes are smoothly guided in the rotational disk. In the unpowered state, brake shoes of the centrifugal shoes engage, frictionally or in a positive-locking way on an outer surface of a friction ring fixed to the motor housing. Upon starting of the drive motor, the brake shoes release the friction ring. The radial displacement of the brake shoes is maintained until the drive motor comes to a stop, wherein the brake shoes 8 are drawn radially inward by spring elements and function again as a locking mechanism. The spring elements are pretensioned such that the brake shoes effect a sufficient retaining torque.Type: GrantFiled: April 28, 2016Date of Patent: June 13, 2017Assignee: JOHNSON ELECTRIC S.A.Inventors: Sten Waehrisch, Matthias Kulke, Wolfgang Winkler
