MECHATRONIC ASSEMBLY FOR DRIVING AN EXTERNAL MEMBER USING A BRUSHLESS MOTOR AND A SIMPLE ASSEMBLY OF ELECTRONIC COMPONENTS

摘要

The invention relates to a mechatronic assembly for positioning a member including a control unit and an actuator, the control unit including a control algorithm and a power bridge, said algorithm controlling said power bridge, the power bridge outputting a two-wire electric signal, the actuator including a polyphase brushless electric motor having N phases (N being or higher), binary probes for detecting the position of the rotor of said motor, and power switches suitable for supplying the N phases of the motor from the two-wire electric signal, characterised in that the state of the power switches is controlled directly by a signal emitted by the detection probes.
