Embodiment Construction

[0038] figure 1 An electric traction machine 10 with direct current and live brushes according to the invention is shown. The motor 10 with winding excitation includes an inductor 11 and an armature 12 . In this case, the armature 12 consists of a rotor provided with windings.

[0039] In addition, the electromagnet contactor is provided with a mechanical power contact K0 belonging together with the armature 12 to the power circuit C_Puis.

[0040] The power contact K0 is controlled by a coil B_cmd belonging to the control circuit C_Com. This circuit C_Com also comprises a contact S, the closing of which commands the activation of the control coil B_cmd, thereby causing the closing of the power contact K0. Electric energy is supplied by the battery Batt, and the power supply voltage is preferably 48V.

[0041] The inductor 11 has a separate winding excitation through which the current Is is independent of the armature current Ir. The inductor 11 is electrically connected ...

Abstract

The invention mainly relates to a DC and brushed rotating electrical machine (10) for traction, comprising an armature (12) formed by a rotor provided with a winding and an inductor (11), characterised in that the inductor (11) has a separate excitation coil, through which an inductor current (Is) passes that is independent of an armature current (Ir), and in that the inductor (11) is capable of discretely generating, by selecting coils (B1, B2, B3) through which the inductor current (Is) passes, at least three different magnetic flux levels each corresponding to a traction mode (M1, M2, M3) of the rotating electrical machine.

Description

technical field [0001] The invention relates to a rotary electric traction machine for motor vehicles with flux switching. The invention has a particularly advantageous application for the propulsion of electric vehicles with low power, especially 4kW to 5kW. Thus, the invention can be advantageously used in particular in low-power four-wheel electric vehicles (micro-vehicles), two-wheel vehicles of the motorcycle type or heavy four-wheel vehicles. Background technique [0002] Almost all known systems for traction of electric vehicles are based on AC electric motors, synchronous or asynchronous with permanent magnets. However, the brushless multi-phase architecture has the disadvantage of high cost due to the use of position sensors and integrated switching elements in the inverter. [0003] Propulsion systems for electric vehicles are also known, which are based on DC motors with brushes and have separate excitations. The control of the motor basically consists of the r...
