Abstract

A permanent magnet generator driven by an automobile engine belongs to the technical field of automobile electric appliances. It includes a stator and a rotor, and is characterized in that: the rotor rotates on the inner ring of the stator, the rotor includes a rotor core frame (7) and a rotor core (8), and a rotor shaft (3) is arranged at the axis of the rotor core frame (7); Several stator cores (2) and multi-phase armature windings (4) are arranged on the stator, and the armature windings (4) are wound on different stator cores (2) in sequence; two stator cores (2) of each stator core (2) Armature windings (4) and auxiliary windings (5) are respectively arranged on the poles, and permanent magnets (1) are obliquely arranged in the stator cores (2), and the permanent magnets (1) are embedded in each stator core (2) with the same side of the stator pole. In the permanent magnet generator driven by the automobile engine, the magnetic field is adjusted and the field weakening control is realized by setting the auxiliary winding in the stator core.

Description

Technical field [0001] A car engine drives permanent magnet generator, belongs to the field of automotive appliances. Background technique [0002] At present, a DC power system often supplies electric energy for its electricity equipment, and is often used in these DC power systems, brushless DC permanent magnet motors and claw poles motors. Electrical incentive brushless DC generators can combine brushless DC generators with good reliability and electrical exciting generators to facilitate adjustment of output voltages and to achieve weak magnetic control. However, the electrical exciting generator excitation loss run separately and low efficiency. [0003] The permanent magnet generator has the advantages of large energy density, high efficiency, which can output high quality DC voltage, but there is a permanent magnet in which it is inherently weak. Due to the use of permanent magnet materials, the motor is difficult to regulate when the motor is running, and the external out...
