Abstract
The generator uses orthogonal harmonic excitation technique, concentric type windings with unequal circles, and waveform deviation factor reaches to 0.72%. Rotor uses structure of integral punched piece of salient pole. The insulation level is H so as to reduce engine base number, producing motor in small size and lightweight. Structure design uses rotor magnetic pole made from 2mm 'V' shaped spring steel sheet so as to improve effect of ventilation and heat dispersion.
Description
Technical field
The present invention relates to a kind of generator, especially a kind of salient pole integral rotor no-brush synchronous generator.
Background technology
Along with China becomes a full member of WTO, external electromechanical shock domestic market, except motor performance, to motor volume, weight, structure, appearance requirement is more and more higher.
Summary of the invention
The object of the present invention is to provide a kind of salient pole integral rotor no-brush synchronous generator, this generator volume is little, and axial dimension is short, and is in light weight, satisfies all types of user needs, client particularly peculiar to vessel.
Technical scheme of the present invention is: a kind of salient pole integral rotor no-brush synchronous generator, this generator unit stator winding adopt single, double layer concentric type unequal-turn structure, and the rotor with salient pole pole lamination is an integral type, and rotor coil is directly on pole lamination." V " shape steel spring plate support rotor magnetic pole has been adopted in the rotor structure design.
The invention has the advantages that: adopted the quadrature harmonics wave technology, do not waited circle concentric type winding, aberration rate is little, and the non-loaded line voltage-form distortion rate reaches 0.72%, has guaranteed the supply waveform quality.Realized the rotor punching integration, improved heat radiation and ventilation effect, temperature rise also reduces greatly, and rotor structure is very reliable.This generator adopts single supporting and salient pole integral rotor structure, and volume is little, in light weight, good looking appearance, applied range.
Description of drawings
Fig. 1 is a salient pole integral rotor no-brush synchronous generator structural representation of the present invention;
Fig. 2 is a salient pole integral rotor no-brush synchronous generator rotor structure schematic diagram of the present invention.
Embodiment
A kind of salient pole integral rotor no-brush synchronous generator, fan 6 adopts the radial structure, the steel plate welding, thereby the air quantity that fan 6 produces is big, and the efficient height, noise is little, and cost is but low more than cast aluminium.Exciter armature 8 is built-in, has ventilation window in motor body bottom, and is protected with protective cover 9.This generator unit stator 1 winding adopts single, double layer concentric type unequal-turn structure, rotor 2 magnet limbs punchings 3 are integral types, be furnished with damping hole 4 in the magnet limbs punching 3, rotor coil 5 is directly in magnet limbs punching 3, be insulated layer pad 10 parcels around the rotor coil 5, this rotor coil 5 fixedly be very safe and reliable.Rotor 2 structural designs have adopted " V " shape steel spring plate 7 support rotor magnetic poles, and 5 of adjacent two rotor coils are provided with bracer 11, and the interpolar draught area is big, ventilation effect is splendid, so the improvement of rotor 2 structures has enlarged the magnetic conduction sectional area, has also improved heat radiation greatly, has reduced temperature rise.
