摘要:
A vehicle has an engine driving an alternator. The electrical energy supplied by the alternator feeds an electric traction motor, via a rectifier, an electric line, and an inverter. The electric traction motor is mechanically coupled to a wheel. A super-capacitor is connected to the electric line by a voltage-matching circuit. A unit for controlling the torque applied to the vehicle wheel manages the circulation of the electrical energy in the drivetrain so as always to discharge the super-capacitor as a priority, in order to be able to be ready to recover the energy at the next braking.

A method is provided for manufacturing a stator of an electrical rotating machine. The method includes: impregnating a first winding head with a first composition that includes a heat-setting resin and a filler of a first particle size; impregnating conductive wires in a slot region with a slot-impregnating composition that includes a heat-setting resin and another filler of a second particle size smaller than the first particle size of the filler of the first composition; and impregnating a second winding head with a composition that includes a heat-setting resin and a filler of a particle size larger than the second particle size.
摘要:
The stator for an electrical machine comprises a laminated magnetic circuit 1 having a plurality of teeth delimiting longitudinally oriented slots, electrically conductive wires 2 being disposed in the slots, and winding heads 3 at the ends of the stator. An outer sheath 4 forms part of the final motor. The stator includes a composition 6 for impregnating the winding heads, of which the filler has a large particle size, and a slot-impregnating composition 8, containing a filler of smaller particle size.
