Son and production method, belong to technical field of motor manufacture.
Background technique
No-brush synchronous generator loads various kinds of equipment and provides different capacity and voltage, is widely used in electric power and new energy
Field.It is mainly made of main generator, exciter and excitation system three parts, wherein main generator is field-rotatable type power generation
Machine, exciter are pivot-rotatable type generator.After exciter rotor rotation, the remanent magnetism of main rotor induces remanent magnetism voltage on stator,
This voltage provides exciting current to exciter stator after excitation system, and exciter rotor is mentioned through rotating rectifier to main rotor
For excitation field current, to generate corresponding magnetic field, bigger induced voltage is thus generated on stator, the voltage is through above-mentioned
As soon as path loops back and forth like this to form a positive feedback process, the voltage of generator is set up.

Mild steel, another kind are silicon steel sheets, several magnetic poles of salient pole are sleeved on centralized magnet exciting coil, carry out vacuum after binding and fixing
Pressure immersion varnish (VPI) is simultaneously dried.
At present without the no-brush synchronous generator of permanent magnetic auxiliary exciter, mainly there is following defect:
1, generator (such as emergency generator) is long placed in for operating condition, just needs first to fill exciter stator when operation again
Ability normal power generation after magnetic, process is cumbersome, influences emergency reaction speed.
2, generator manufacture after the completion of, transient reactance parameter and inherent characteristic have been cured, when actual value with set
Evaluation has biggish deviation, may result in generator dynamic property and is not able to satisfy standard or the requirement of user, at this time if
Only response mode (PID) parameter between the output and input for adjusting excitation system, also without too big improvement.
3, when generator is using number automatic voltage regulator (AVR), if the practical exciting current of generator compares design value
Greatly, have exceeded the range of AVR, such as design exciting current value be 7A, originally be 8A exciting current value, actual value is but greater than
In 8A.
The method for solving the problems, such as 1 at present is to increase permanent magnetic auxiliary exciter, solves the problems, such as that 2 method is that increase main generator is superfluous
Remaining design solves the problems, such as that 3 method is to replace the AVR of a greater amount of journeys, and although these solutions can solve loss of excitation, dynamic special
Property and exciting current exceed AVR range problem, but this increases generator outer dimension and weight, considerably increases generator
Manufacturing cost.
It is such as required according to user, needs to directly initiate 27.5kW blower with 50kW/400V no-brush synchronous generator, it is desirable that pressure
Drop is not more than 25%.It is 26.2%, Bu Nengman that existing 50kW, 400V no-brush synchronous generator, which directly initiates 27.5kW blower pressure drop,
Sufficient user requires.
