Definitions
- Such an electric supercharger is conventionally implemented in the air intake line of a combustion engine of a motor vehicle, upstream or downstream of a turbocharger.
- a compressor can be implemented on a recirculation line of the exhaust gas of the internal combustion engine.
- the at least one branch piece is made of ferromagnetic material. Also optionally, the at least one branch piece has a maximum relative permeability of between 500 and 2,000.
- Figure 3 is a sectional view of a third electric motor according to the invention.
- the stator 102 further comprises at least two pairs of stator teeth 110, 114 and 112, 116 projecting radially from the frame 108 towards the axis of rotation 106.
- the stator teeth 110, 112, 114, 116 are distributed angularly. in a uniform manner about the axis of rotation 106, and each pair has two stator teeth 110, 114 and 112, 116 opposite one another relative to the axis of rotation 106.
- the two teeth stator 110, 114 and 112, 116 of the same pair are symmetrical with respect to the axis of rotation 106.
- each stator tooth 110, 114, 112, 116 is symmetrical with respect to a median line passing through the axis of rotation 106.
- the rotor 104 extends into the stator 102 and has at least one pair of rotor teeth 126, 128 projecting radially away from the axis of rotation 106.
- the rotor teeth 126, 128 are uniformly distributed around the rotor. axis of rotation 106, and each pair has two rotor teeth 126, 128 opposite one another relative to the axis of rotation 106.
- the electric motor 100 further comprises a bypass piece 130 of magnetic flux.
- the bypass piece 130 is a cylinder extending around the axis of rotation 106, in an air gap between the stator teeth and the rotor teeth.
- the cylinder is circularly centered and centered on the axis of rotation 106.
- the branch piece 130 is fixed to an end face of each stator tooth 110, 112, 114, 116.
- the bypass piece 130 is at the front of the coils 118, 120, 122, 124, that is to say the side of the coils 118, 120, 122, 124 which is opposite the frame 108.
- the electric motor 200 comprises, in place of the bypass piece 130 of Figure 1, a magnetic flux bypass part 202 which is a cylinder extending around the axis of rotation 106, in an air gap between the teeth. stator and rotor teeth.
- the branch piece 202 is attached to an end face of each rotor tooth 126, 128.
- the operation of the electric motor 200 is similar to that of the electric motor 100.
- the electric motor 200 comprises, in place of the bypass piece 130 of FIG. 1, several bypass pieces 302, 304, 306, 308 each having a cylindrical wall shape and connecting each of the lateral faces of respectively two rotor teeth 126 , 128 successive.
- the present invention is not limited to the embodiments described above, but is instead defined by the following claims. It will be apparent to those skilled in the art that modifications can be made.
- bypass parts of several of the embodiments can be combined within the same electric motor.
