Abstract

The invention provides an electric excitation and switched reluctance dual-state motor for automobiles, which belongs to the technical field of automobile motors. It is characterized in that: convex lens-shaped iron core, cast aluminum rotor iron core, stator iron core, excitation winding and armature winding, etc., there are 6X stator poles of unequal width inside the stator iron core, X is a positive integer, the excitation stator pole and the armature are The stator poles are arranged at intervals; the pole arc angle of the excitation stator pole is 24 / X° larger than the pole arc angle of the armature stator pole, and the 5X arc-shaped grooves of the cast aluminum rotor core are embedded with silicon steel sheets. The convex lens-shaped iron core, the excitation winding and the armature winding wound on the stator poles are all concentrated short-moment windings. The technology of the invention is a short-magnetic-circuit motor, and the iron loss is small under the same magnetic density; it has two working states of switched reluctance and electric excitation, so as to adapt to the electric and power generation operation states respectively.

Description

technical field [0001] The invention relates to an electric excitation and switched reluctance dual-state motor for automobiles, which belongs to the technical field of automobile motors. Background technique [0002] Energy saving and environmental protection are the eternal pursuit goals of automobiles. Today's social environment is deteriorating and energy shortages are becoming more and more prominent. The whole society's requirements for energy saving and environmental protection are promoting the development of new energy vehicles. As a representative of new energy vehicles, electric vehicles have gradually become the main direction of development. Drive motor is one of the key technologies to be studied in electric vehicles. It is of great significance to develop electric vehicle drive motors. [0003] A motor-generator can operate both as a motor and as a generator. The driving motor for automobiles should have both functions to supply power to electrical equipme...
