Title:
AN ACTUATOR HAVING A MULTIPHASE MOTOR, AND A METHOD OF CONTROLLING SUCH AN ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2013/076161
Kind Code:
A3
Abstract:
An actuator comprising at least one multiphase motor (100) having phases (101) facing a rotor (102) secured to an outlet shaft associated with a braking member (2) and provided with means for connecting it to a movable element that is to be moved, the motors and the braking member being connected to at least one motor control unit (5) for controlling the motors by powering their phases. The motor has at least four phases wound in such a manner as to avoid a neutral point, and in that the control unit has one single-phase inverter per phase and is arranged to implement a nominal, three-phase mode of control, and a degraded mode of control that enables the rotor to be driven in rotation by powering two non-collinear phases thereof.
