Abstract:
A DC electric rotating machine, such as a starter of an automotive vehicle, includes a stator with salient poles having at least four poles distributed uniformly over the circumference of the stator, a rotor disposed inside the stator, a set of brushes adapted for the electric supply of the rotor, and at least two geometrically opposed salient poles. Each pole includes at least one substantially radial slot in a plane parallel to the axis of rotation of the rotor and preferably passes through the axis of the rotor. By minimizing the reaction fields of the armature, utilization of the magnetic material of the parts of the stator is balanced and a harmful armature reaction effect, which increases saturation of the polar parts of the inductor and which leads to reduction in the driving magnetic torque, is mitigated.
