Abstract

A motorized convertible roof system includes at least a portion of a retractable convertible roof operably driven by an electric motor. The motor is operable to maintain the moved portion of the convertible roof in a predetermined position thereby deterring drifting of the convertible roof. In one aspect of the present invention, back EMF deters motor and convertible roof movement. In another aspect of the present invention, an electric motor can be electrically bypassed for manual movement of a convertible roof without necessitating physical disengagement or decoupling of the motor, gears or linkage mechanism.
