Problems solved by technology

Brushed AC synchronous generators have disadvantages such as high failure rate, difficult maintenance, high cost, and unstable operation due to the excitation copper ring, carbon brush and brush holder device.
Since the self-excited brushless alternator adopts the self-compounding rectifier excitation system, it also has the disadvantages of unstable operation, complicated process, large load voltage drop, unstable frequency, and high manufacturing cost.

Embodiment Construction

[0007] The present invention will be further described below in conjunction with the accompanying drawings.

[0008] Referring to the accompanying drawings, a generator stator 2 is installed on the inner wall of the motor housing 1 of the brushless other-excited alternator. The generator stator 2 can be directly used as a generator housing, and a generator coil winding 3 is wound on the generator stator 2. The two ends of the motor shell 1 are equipped with motor end covers 12, 13, and the end cover is equipped with a bearing 14. The bearing 14 is set on the generator shaft 11, and the magneto core 8 and the excitation field are also set on the generator shaft. The iron core 4, the magneto generator winding 9 are wound on the magneto core 8, the generator excitation winding 5 is wound on the excitation core 4, and the potential generated by the magneto generator winding is rectified and added to the generator excitation winding 5 to generate a magnetic field, so that the gener...

Abstract

This invention relates to a brushless ac generator excited by a magnetor. The invented generator comprises: a casing, megnetor, stator, rotor; all of the three being placed in the casing. It is characterised by: permanent magnet and magnetic field produced by magnetor being combined to regulate magnetic field intensity, to control the output voltage from generator coil of magnetor; then, to control exciting current of brushless generator; to let the output volatage from the generator being stable. The iron core and generating winding of the magnetor, together with exciting iron core and exciting winding of the brushless ac generator to form the rotor of the brushless ac generator. The brushless, excited, automatic voltage-stabilizer is composed of: voltage regulator, permanent magnet of magnetor, electromagnet and the rotor of brushless ac generator. Advantages are: small sized, low cost, no noise, high efficiency.

Description

technical field [0001] The invention relates to a brushless alternator adopting a magneto separately excited type, which is suitable for mobile or fixed generating sets powered by diesel engines, gasoline engines and other fuel engines. Background technique [0002] At present, alternators are generally divided into brushed AC synchronous generators and self-excited brushless alternators. Brushed AC synchronous generators have disadvantages such as high failure rate, difficult maintenance, high cost, and unstable operation due to the excitation copper ring, carbon brush and brush holder device. Since the self-excited brushless alternator adopts the self-compounding rectifier excitation system, it also has disadvantages such as unstable operation, complicated process, large load voltage drop, unstable frequency, and high manufacturing cost. Contents of the invention [0003] The object of the present invention is to design a brushless alternator of magneto separately excit...
