摘要:
An electric braking system for a vehicle includes first and second sub-systems connected to each other by an electric line. The first sub-system, which includes a first dissipation device, controls braking in a first wheel set. The second sub-system, which includes a second dissipation device, controls braking in a second wheel set different from the first wheel set. The electric line is arranged such that: if the first dissipation device becomes inoperative, electrical power produced by the first sub-system is channeled towards the second dissipation device, and if the second dissipation device becomes inoperative, electrical power produced by the second sub-system is channeled towards the first dissipation device.

摘要:
A method for manufacturing a stator of an electrical rotating machine that is configured to have a rotor mounted inside the stator. The stator has a laminated magnetic circuit having a stack of magnetic metal sheets disposed substantially parallel to a plane perpendicular to the axis of rotation of the rotor of the machine. The magnetic circuit has teeth that delimit longitudinally oriented slots. The method includes the step of installing electrically conductive wires in the slots and forming winding heads at the two axial ends of the magnetic circuit and installing this assembly on a vertical axis. The assembly is trapped between an outer sheath, forming part of the final motor, and a removable inner core substantially occupying a volume reserved for the rotor. The conductive wires in the slots are impregnated under vacuum with a slot-impregnating composition including a heat-setting resin and a filler, and the composition is polymerized.

A driving inverter for a multi-phase electric motor includes an alternating current (AC) generator, at least one AC sensor, a power supply line, a current sensor, an input, and a controller. The AC delivers current to a terminal block that is connectable to the phases of the electric motor. The at least one AC sensor is arranged on a certain phase or certain phases powering the electric motor. The current sensor is arranged on the power supply line and senses a current thereon. The input receives information that includes a torque demand setpoint and at least one limit current value of a power source. The controller drives phase currents of the electric motor according to the torque demand setpoint and by keeping the current of the power supply line at an acceptable value according to the at least one limit current value of the power source. With the arrangement of the driving inverter, a maximum current can always be imposed on the power source with no risk of degrading it.
