Problems solved by technology

[0003] Taking the generator as an example, if the generated back EMF voltage contains a large ripple component (that is, a large harmonic content), the efficiency of the generator will be reduced, and at the same time, the cogging torque caused by the change of the reluctance at low speed And the vibration and noise phenomenon caused also need to have improvement countermeasures

Embodiment Construction

[0019] Relevant technical content and detailed description of the present invention, cooperate accompanying drawing to illustrate as follows:

[0020] See figure 1 and figure 2 are respectively the schematic diagram of the first embodiment of the present invention and figure 1 Sectional view of line A-A. The brushless permanent magnet synchronous generator is a brushless permanent magnet synchronous generator structure of an outer rotor or an inner rotor. A rotor 10 and a stator (not shown in the figure) of the brushless permanent magnet synchronous generator can be designed as a structure that can generate a deflection acting magnetic field at a specific tilt angle, so as to greatly reduce the brushless permanent magnet synchronous The output ripple voltage of the generator can effectively suppress the vibration and noise problems of the generator and increase its performance and application range. As shown in the figure, the brushless permanent magnet synchronous genera...

Abstract

The invention discloses a brushless permanent magnet synchronous generator for reducing output ripple voltage, which comprises a rotor and a stator. The rotor is made by a plurality of permanent magnet pieces and provides a plurality of magnetic poles; the stator is made by stacking and tightly fixing a plurality of circular silicon-steel sheets, and a plurality of tooth sockets are arranged around the stator for providing winding wiring. The rotor of the brushless permanent magnet synchronous generator is designed to generate a slanting action magnetic field with a special oblique angle to greatly reduce the output ripple voltage of the brushless permanent magnet synchronous generator, thereby the quality of the electric energy outputted by the generator is improved, i.e. better waveformfactors(reduced harmonic content) are achieved, the efficiency of the generator is enhanced, the problems of vibration and noise of the generator can be effectively solved, and the performance and theapplication range of the generator can be improved.

Description

technical field [0001] The invention relates to a brushless permanent magnet synchronous generator, in particular to a brushless permanent magnet synchronous generator which reduces output ripple voltage. Background technique [0002] The machinery that realizes the conversion between mechanical energy and electrical energy and converts electrical energy mainly includes transformers and rotating electrical machines. It is usually based on the phenomenon of electromagnetic induction, but there are also motors that use static electricity and piezoelectric effects. Transformer is a power conversion device with no relative movement between components, and is widely used in power transmission, voltage, current, impedance transformation and circuit isolation. A rotating electrical machine is an electromechanical energy conversion device, which is mainly used as a generator to convert mechanical energy into electrical energy; or as a motor to convert electrical energy into mechani...
