Problems solved by technology

[0002] At present, the commonly used stator windings of automobile generators are either connected in three-phase star or three-delta. The characteristic is that the line voltage is high and the output current is small, that is, there is a certain current output when working at low speed, but it cannot provide enough current for the car at high speed. The characteristic of the delta connection is that the output current at high speed Large, but there is almost no current output when working at low speeds, so the car is very easy to lose power
Obviously, the above two kinds of generators all have deficiencies in terms of power supply for automobiles.

Embodiment Construction

[0014] Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail;

[0015] The power generation method of the permanent magnet generator for vehicles of the present invention is realized in this way. On the stator core of the permanent magnet generator for vehicles, multiple groups of coils with different numbers of turns are wound, some coils have more turns, some coils have more turns Driven by the automobile engine, at low speed, the coil with more turns has a certain current output, and at high speed, the coil with fewer turns can generate a large enough output current, and the output current of each coil is stabilized by its own rectifier. The voltage device rectifies and stabilizes the voltage for use by automobiles.

[0016] Such as figure 1 As shown, the permanent magnet generator of the present invention mainly consists of a rear end cover 1, a permanent magnet rotor 2, a stator 3, a front end cover 4, a cover 5,...

Abstract

An electric generation method for the permanent-magnet electric generator for car and its equipment is disclosed. Multiple groups of windings with different numbers of turns are wound on the stator core. The windings with more turns can output current at lower speed and the windings with less turns can output current at high speed. It features generation of a certain current during low speed and generation of some current large enough during high speed.

Description

Technical field: [0001] The invention relates to a permanent magnet generator, which is suitable for various motor vehicles as a power supply for charging and supplying power. Background technique: [0002] At present, the commonly used stator windings of automobile generators are either connected in three-phase star or three-delta. The characteristic is that the line voltage is high and the output current is small, that is, there is a certain current output when working at low speed, but it cannot provide enough current for the car at high speed. The characteristic of the delta connection is that the output current at high speed Large, but there is almost no current output when working at low speeds, so the car is extremely prone to power loss. Obviously, above-mentioned two kinds of generators all have deficiencies aspect automobile power supply. Invention content: [0003] The purpose of the present invention is to provide a permanent magnet generator for vehicles tha...
