ELECTRIC ACTUATOR WITH CONTROL SENSOR, AND DISC BRAKE COMPRISING SUCH ACTUATOR

摘要

An electric actuator comprises a housing which contains a screw mechanism and an electric motor which is driveably connected to the screw mechanism, said screw mechanism providing a linear movement in response to a rotational movement of the electric motor and comprising a screw and a nut, one of which is supported with respect to the housing, a sensor being provided for measuring a quantity related to the rotational movement and/or the linear movement of the screw mechanism. A control unit for monitoring and/or influencing the rotational and/or the linear movement of the screw mechanism on the bases of signals from the sensor has been provided.
