Abstract
A mechatronic assembly for linearly driving a member includes a control unit and an actuator, the control unit including a control algorithm and a power bridge, the algorithm controlling the power bridge, the power bridge providing a bifilar electrical signal consisting of a torque signal and a direction signal, the actuator including an electric motor which does not have an N-phase multiphase brush, binary probes for detecting the position of the rotor of the motor, a device for transforming the rotational movement of the rotor into a linear movement of the control member, power switches capable of powering the N phases of the motor on the basis of the bifilar electrical signal, and the state of the power switches is controlled directly by a signal from the detection probes.
