Abstract

The invention provides a low-harmonic-content motor generator of an electric automobile, and belongs to the technical field of automobile motors. The motor generator is characterized in that the motorgenerator comprises a stator iron core, an excitation winding, an armature winding, a block rotor, a non-magnetic rotor iron core and a shaft; and twelve stator poles with the same width are arrangedon the inner side of the stator iron core, eight block rotor iron cores capable of conducting magnetism are embedded in an arc-shaped groove of the non-magnetic rotor, the exciting windings and the armature windings are all centralized short-moment windings, the exciting windings are wound on the stator iron core at intervals, and the armature windings are wound on the stator poles between the two exciting windings. 1-4 parallel U-shaped air gap magnetic barriers are linearly cut out in each block rotor core, and the air inlet gap magnetic barrier is filled with a non-magnetic light material.The motor generator is a short magnetic circuit motor, and the iron loss is small under the same flux density; and the windings are short-moment windings and are not overlapped, so that heating of the motor is reduced. And the air gap magnetic barriers on the block rotors can effectively reduce even harmonics of the counter electromotive force of the motor, and the stability of operation is improved.

Description

technical field [0001] The invention relates to a motor generator with low harmonic content for electric vehicles, 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 these two functions, which can supply power to electrical equipmen...
