Abstract

The present invention relates to an automobile engine-driven permanent magnet generator, and belongs to the technical field of automobile electric appliances. The magnet generator comprises a stator and a rotor, and is characterized in that the rotor rotates in the inner ring of the stator, the rotor comprises a rotor iron core frame (7) and a rotor iron core (8), and a rotor shaft (3) is arrangedat the axis of the rotor iron core frame (7); a plurality of stator cores (2) and multi-phase armature windings (4) are arranged on the stator, and the armature windings (4) are sequentially wound ondifferent stator cores (2); two stator poles of each stator core (2) are respectively provided with an armature winding (4) and an auxiliary winding (5), a permanent magnet (1) is obliquely arrangedin each stator core (2), and the permanent magnets (1) are embedded in the stator poles on the same side of each stator core (2). In the automobile engine-driven permanent magnet generator, the auxiliary windings is arranged in the stator cores, so that a magnetic field is adjusted, and flux weakening control is realized.

Description

technical field [0001] An automobile engine-driven permanent magnet generator belongs to the technical field of automobile electrical appliances. Background technique [0002] At present, DC power systems are often used in automobiles to provide electrical energy for their electrical equipment. Brush DC motors, brushless DC permanent magnet motors and claw-pole motors are often used in these DC power systems. The electric excitation brushless DC generator can have the advantages of good reliability of the brushless DC generator, easy adjustment of the output voltage and easy field weakening control of the electric excitation generator. However, the excitation loss of the electric excitation generator running alone is large and the efficiency is low. [0003] Permanent magnet generator has the advantages of high energy density and high efficiency, and can output high-quality DC voltage, but its internal permanent magnet is its inherent weakness. Due to the use of permanent ...
