Abstract
A mechatronic assembly drives a member intended to be linked to a DC electrical power source and to an ECU control unit. The ECU includes a computer for executing a feedback control algorithm delivering an item of direction and torque information. The assembly includes an actuator formed by a brushless polyphase electric motor having N phases, binary detection probes for detecting the position of the rotor of the motor, an electronic circuit comprising a power bridge for powering the N phases of the motor. It further includes an onboard electronic control circuit without a microcontroller, computer and memory of which the input receives the item of direction and torque information from the ECU and of which the output controls the power bridge directly modulating the current of the DC electrical power source applied to each of the phases of the motor, and the torque and direction information provided by the ECU is separate from the power signal delivered only by the power source.
