The permanent magnet and the exciting coil can also be positioned in a same main claw pole; the permanent magnet is connected in series with the magnetic circuit which is generated by the excitation current, and the permanent magnet is static.
Description
The utility model relates to a kind of silicon rectification generator, the brushless silicon rectification generator of especially a kind of compound excitation.Belong to the class generator field.
For utilizing the permanent magnet generator advantage, remedy the shortcoming that voltage can not be regulated, theoretical and design one book (the Tang Renyuan volume of modern magneto, China Machine Press 1997 publishes,) propose to imagine by the compound excitation that permanent magnetism provides base excitation to be regulated by electric excitation, but do not propose to be applied to the generator and the concrete magnetic structure of which kind of form,, do not met application example yet from a few days ago on.
The purpose of this utility model is to overcome the shortcoming in the above-mentioned prior art, has proposed the brushless silicon rectification generator of a kind of compound excitation, only is used for just can having fairly obvious economic worth on small fishing vessel, the seagoing vessel.
The technical solution of the utility model is for mainly comprising: stator winding and iron core thereof, magnet exciting coil, permanent magnet claw pole, permanent magnet, rotating shaft, the axial prong utmost point, coil rack, rectifier diode, fan, voltage regulator, permanent magnet are installed in the independently interior magnetic path parallel connection that produces with exciting current of permanent magnet claw pole, and permanent magnet rotates together with the axis.Permanent magnet also can with magnet exciting coil coexist axial prong extremely in, connect with the magnetic circuit that exciting current produces, permanent magnet is static.Its air-gap flux was provided by permanent magnet when generator ran up, and equaled a permanent magnet AC synchronous generator.During low-speed running, air-gap flux is provided jointly by permanent magnet and exciting current, equals a compound excitation synchronous alternating-current generator.Rotating speed during load variations, is regulated exciting current, and resultant flux is tending towards constant in the air gap, thereby generator voltage is kept in the permissible value scope.
The utility model is compared with conventional silicon rectification generator, has tangible advantage: at first in the working speed scope of broadness, do not rely on storage battery and supply with exciting current.Do not need any operation and caution during excitation, needn't worry to burn out magnet exciting coil yet.In the generating of all can encouraging oneself of no storage battery occasion, enlarged the scope of application.Secondly, exciting current is little, and loss is little, the efficient height.Generator voltage can be adjusted arbitrarily, and is simple to operate, easy to use.
Further describe below in conjunction with accompanying drawing:
The structural representation of Fig. 1 permanent magnet in permanent magnet claw pole independently
Fig. 2 permanent magnet and the magnet exciting coil structural representation of axial prong in extremely that coexist
Fig. 3 the utility model is electrically connected schematic diagram
As shown in Figure 1 and Figure 2, the utility model mainly comprises: stator winding and iron core 1 thereof, magnet exciting coil 2, permanent magnet claw pole 3, permanent magnet 4, rotating shaft 5, the axial prong utmost point 6, coil rack 7, rectifier diode 8, fan 9, voltage regulator 10, permanent magnet 4 is installed in the independently permanent magnet claw pole 3 interior magnetic path parallel connections that produce with exciting current, and permanent magnet 4 is with axle 5 rotations.Permanent magnet 4 also can coexist in the axial prong utmost point 6 with magnet exciting coil 2, connects with the magnetic circuit that exciting current produces, and permanent magnet 4 is static.Its air-gap flux was provided by permanent magnet 4 when generator ran up, and equaled a permanent magnet AC synchronous generator.During low-speed running, air-gap flux is provided jointly by permanent magnet 4 and exciting current, equals a compound excitation synchronous alternating-current generator.Rotating speed during load variations, is regulated exciting current, and resultant flux is tending towards constant in the air gap, thereby generator voltage is kept in the permissible value scope.The utility model can be implemented according to the circuit diagram of Fig. 3, and energized circuit: the stator alternating voltage is through diode V
1, V
2The three-phase bridge rectification output DC is for energized circuit, and its current path is diode V
2Positive pole → magnet exciting coil 2 → voltage regulator 10 → diode V
1Negative pole, the magnetic line of force that permanent magnet 4 and exciting current produce is divided into the N utmost point and the S utmost point to the axial prong utmost point 6.And in air gap, produce resultant flux.Magnetic line of force path: the N utmost point → main air gap a → stator winding and iron core 1 thereof → main air gap a → S utmost point → additional air gap b → coil rack 7 → additional air gap c → N is extremely closed.When 6 rotations of the axial prong utmost point, stator winding 1 cutting magnetic line induces the interchange electromotive force on stator winding 1.Through diode V
1The three-phase bridge rectification output DC is for load.The stator harmonic voltage is through diode V
3And V
1The three phase full wave rectification output DC improves generator output for load.
