Abstract: An electric machine stator having a stator yoke having a circular surface and a plurality of stator teeth standing on the circular surface. Each of the stator teeth including, on the one hand, a stack of plates made of grain-oriented steel, having a first end connected to the yoke and an opposite second free end and, on the other hand, an electrical wire winding, each of the plates extending according to a direction normal to the circular surface, whereas the grains are oriented parallel to the normal direction. Each of the plates is cut into a T-shape forming two lips, so that the second free end has two opposite free flanges; and each of the plates is treated so as to disorient the grains at the level of their two lips.

Abstract: A stator of an axial-flow rotary electrical machine and a production method. The stator has: a support ring having N teeth each extending as an axial component as far as a top, said N teeth being separated respectively from one another by N housings; N conductive-wire windings respectively wound around said N teeth; N pairs of wings respectively secured to the tops of the N teeth, the two wings of each of said N pairs extending laterally opposite each other and respectively in line with each of the N windings. The N pairs of wings are at least partially embedded together in a single piece forming a cover and fitting on top of the N teeth, so as to confine said N housings so as to be able to refrigerate the N housings.

Abstract: An axial-flux electric machine includes a housing and first and second stators including first and second circular buses having conductive tracks on which are arranged connection terminals allowing connection to the coils of the stators and which are supplied by supply phases. The circular buses and the coils are interchangeable between stators. The machine also includes indexing devices that position the circular buses in the housing so as to place facing a connection terminal of the first circular bus and a connection terminal of the second circular bus that are supplied by a same supply phase.

Abstract: Disclosed is a method for assembling a magnetic pole element for a rotor for an axial flow electric machine, the rotor including a body in the form of a disk having at least one housing, the magnetic pole element including a plurality of single magnets, the method including the following steps: e1) forming a first row of at least two single magnets and retaining the single magnets using a strip of adhesive material; e2) placing the first row on a support having a curvature that is equal or substantially equal to the curvature of a peripheral edge of the housing; e3) forming another row of at least two other single magnets and retaining the single magnets using another adhesive material strip; e4) placing the other row on the first row; and e5) repeating steps e3) and e4) until the magnetic pole element is assembled.

Abstract: A stator body for an axial-flux electric machine includes: a plate in the form of a ring centered on a longitudinal axis, the plate including an upper face and at least one upper relief projecting from the upper face; and teeth, at least one of which includes a lower relief, a first side of which has a shape complementary to that of a portion of the upper relief, the upper relief being interlocked with the lower relief. The body includes a locking element extending opposite the upper face of the plate and interposed between the tooth and the plate so as to immobilize the upper relief in the position interlocked with the lower relief, and blocking unit blocking the position of the locking element with respect to the plate.

Abstract: A stator body for an electric machine, including: —at least one fixing support centered on a longitudinal axis, —teeth which are designed to accept coils of electrically conducting wire and which are uniformly distributed about the longitudinal axis, and—fixing means each suitable for fixing one of the teeth to the fixing support. Each fixing means includes: —at least one first key at least partially housed in a first keyway provided in the tooth, —at least one second key at least partially housed in a second keyway provided in the fixing support, and—at least one immobilizing element designed to immobilize the first key with respect to the second key.

Abstract: Disclosed is an element with magnetic poles for the rotor of an axial flux electric machine, including an assembly of several individual magnets and a flange, at least a first part of which surrounds the assembly in order to immobilise the individual magnets in position. At least one part of the flange is made from a material including a mixture of polymer and magnet powder.
