Abstract
A drive assembly for an electromechanical brake actuator. The drive assembly includes: an electric motor; a transmission coupled to the motor, having an actuating member that is couplable to a pressure generating device and linearly adjustable by the motor against a restoring force to actuate the pressure generating device; a control device electrically connected to the motor for controlling the motor; a switch activatable by the transmission by a movement of the actuating member, and an electric braking circuit electrically connected to the motor and the switch and is activatable by activating the switch and an electrical activation voltage; wherein the activation voltage is generated by the motor when the motor acts as a generator when the control device fails by absorbing the restoring force acting on the actuating member, and the braking circuit brakes the motor to generate a force that counteracts the restoring force by the motor.
