Abstract: An apparatus for opening and closing a barrier includes a rotatable housing having a first stop surface extending outwardly from an outer surface of the housing, said housing being configured for attachment of said barrier; an electric motor disposed within the housing, said motor having a rotor coupled to a first shaft having an axis, said motor further including a stator fixedly coupled to said housing; a member configured to receive and mechanically fix an end of a second shaft thereto; and a mounting bracket configured for connection to a fixed post, said mounting bracket connected to the member and having a second adjustable stop surface configured to contact the first stop surface and limit rotational movement of said housing relative to said mounting bracket in a first rotational direction, wherein the motor is configured to be selectively activated to effect relative rotational movement of the rotor relative to the stator, and the rotational movement of the motor relative to the mounting bracket causes rotational movement of the housing relative to the mounting bracket. Other apparatuses for opening and closing a barrier are also described.
