A smart motor having an electromechanical converter endowed with a rotating portion defining an axial direction and a radial direction, an electronic control unit, an electrical filter and a housing having a cooling device, the electromechanical converter, the electronic control unit and the filter being accommodated inside the housing, and the electronic control unit comprising an electrical converter configured to power the electromechanical converter. The housing is cylindrical and the electrical converter includes one or more electronic board(s) forming a hollow cylinder.

Compact smart electric motor

An electrical filtering system including capacitors and an electrical distribution device including a stack of two electrically conducting layers facing one another and separated by an insulating layer, the stack being mounted on a rigid insulating plate, and said capacitors being mounted on said distribution device, the rigid plate extending in a plane orthogonal to the direction in which the layers are stacked. The distribution device includes a plurality of electrical connections distributed angularly over the outer perimeter of the distribution device and protruding in a plane parallel to the plane in which the rigid plate extends, and extending from the outer perimeter of the distribution device, each of the connections being, on the one hand, connected to at least one capacitor and, on the other hand, intended to be connected to an arm of an electrical inverter mounted on a tubular electrical converter of an electronic control unit.

Electrical filtering system for a smart electric motor with decoupled multiple windings and associated smart electric motor

A smart motor having a permanent magnet synchronous machine and an electronic control unit, the synchronous machine including one or two permanent magnet rotor(s) and at least one six-phase stator per rotor endowed with at least two three-phase assemblies each formed of three windings electrically coupled in a star, the electronic control unit including one control inverter per stator equipped with six independent arms each configured to control one phase of a six-phase stator. The three-phase assemblies are magnetically and electrically decoupled with respect to one another.
