Technical field
The present invention needs to be equipped with the situation that high-power engine just can reach specified output for solving conventional motors inefficiency, mates rectifier power supply module system simultaneously and after engine composition generating set.
Background technology
Because increasing home or overseas base station needs stationary power generation machine now, and unit rear end all have matched DC rectifier module, but conventional electric generators is excitation 3 phase 2 pole generator or weak magnetic 3 phase 2 pole generator, inefficiency, needs coupling high-power engine just can reach specified output, and output waveform only 3 rectification wave heads, rectification effect is not good, whole generating set loss is high, and inefficiency, power stability is poor.
Summary of the invention
The technical solution used in the present invention is, magneto rotor magnetic field adopts the strong magnetic magnet of neodymium iron boron to set up, electric machine rotor adopts short core construction to reach minimizing iron loss, copper loss, the object of magnetic loss, electric efficiency is higher, stationary part contains 2 cover Y and connects winding, in 30 degree of electric angle distributions between winding and winding, 8 output lines altogether, 2 cover windings respectively account for a half-power, the mode of power is shared by 2 cover windings, realize the stationarity that band carries output mode, because distributing in 30 degree of electric angles between winding and winding, power supply output waveform can be made to form the situation of 12 wave heads, better rectification, rectification angle is less, power stability is better.
Described efficient 6 extremely two Y alternating current generators, is characterized in that: magneto alternator comprises rotor, stator, fan, and rotor adopts 3 pairs of strong magnetic magnet of neodymium iron boron, and stator adopts 36 grooves.
1. magneto alternator adopts neodymium iron boron strong magnetic magnet electric motor rotor and DC dual stator winding technology, and structure is simple, and lightweight, efficiency is high, and AC power output quality is stablized, and cyclic duration factor is high, failure rate is low.
Below in conjunction with accompanying drawing to the utility model further instruction.
