Abstract: Polyphase electric machine including a first motion actuation assembly and a rotatable second motion actuation assembly, the first and second motion actuation assemblies together defining first and second opposing lateral faces, of the polyphase electric machine; the polyphase electric machine further having at least one phase generator including a plurality of control assemblies, each control assembly containing an input module and an output module, the input and output modules being arranged on the first lateral face and on the second lateral face of the polyphase electric machine.

Abstract: The rotary drive system includes: a direct voltage source (102); an electric motor (104) having an axis of rotation (A), and including independent phases having directions about the axis of rotation; an inverter (106) for connecting each phase to the direct voltage source (102); and a control device (110) for supplying a command to the inverter (106). The control device includes: elements (118) for selecting a formula from predefined formulas, each predefined formula being intended to calculate either a homopolar voltage set-point, or a homopolar current set-point; elements (124) for determining a set-point intended to apply the selected formula to determine, according to the formula selected, either a homopolar voltage set-point, or a homopolar current set-point, and elements (126) for determining a command intended to determine the command of the inverter (106) based on the set-point determined.
