Abstract

The invention relates to a regulating mechanism for operating an actuator or connecting element (11, 12) of an automatic transmission. The regulating mechanism has an actuator (3), a regulating mechanism (4), a transmission element (6), and an output element (8, 9). According to the present invention, the actuator (3) is configured as a three phase motor, advantageously as an asynchronous motor. The torque (M) of the actuator (3) is converted into an actuating force (S) in the transmission element (6), which is then applied to a regulated and or connecting element (11, 12).
