Abstract
A brushless inductor-type electric generator for car is characterized by that the stator core of said electric generator has big and small slots, the stator winding is composed of armature winding (three-phase or single-phase) and exciting winding, and is embedded in said big and small slots, the rotor is made up of magnetic solid steel body or laminated structure, and the rotor has specially designed teeth and slots, but no coil, so its structure is simple and firm, and its mechanical strength is high, vibration resistance is strong, and the service life of electric generator is long. Because of the brushless, eliminate the spark in operation, like claw pole generator, not only reduce the interference to the vehicle radio equipment, but also the maintenance cost is little.
Description
The utility model relates to a kind of brushless type inductor-type generator.Applicable to automobile current generator and other kinds micro generation unit.
The generator that loads on the domestic and international dissimilar automobiles adopts traditional form to have the small-sized DC generator of carbon brush and mechanical rectification sheet mostly at present.Spark was big when this automobile current generator moved, easy burn-out commutator segment and carbon brush, and bad mechanical strength under the high rotating speed a little less than the antivibration ability, has interference to vehicular radio, and manufacturing is complicated, cost is high, and service life is low.
On May 11st, 1988 Decree of Patent Office of China the CN87213181.5U utility model patent, having introduced a kind of rotor is the small-sized brushless generator of Lundell, its structural principle is identical with Lundell slip clutch in the electromagnetic varispeed motor, only with regard to the claw-pole motor structure, design has three spaces, decide for inside and outside two, the pawl utmost point at forward and backward two ends needs through being welded to form.Thereby manufacturing processing and assembling etc. are all complicated, and under high rotating speed, mechanical strength is still relatively poor, as the welding quality instability, and the electromagnetic performance in the time of also can influencing the motor operation.
The purpose of this utility model is to provide a kind of brushless inductor type automobile current generator at the deficiencies in the prior art, the stator core that is characterized in this generator has vat and sulculus, stator winding is made up of armature winding (three-phase or single-phase) and excitation winding, and embed in vat and sulculus, rotor is the solid steel body or the lamination of magnetic material, but does not have coil.It is simple in structure, and parts are few, and processing and fabricating is easy, and cost is low; Rotor structure is firm, even if in 12500 rev/mins of operations down at a high speed, electromechanics intensity is also higher, and the antivibration ability is strong, the motor long service life; Since brushless, operating spark eliminated, the same with claw-pole type generator, not only reduced interference, and reduced operating maintenance, recondition expense vehicular radio.
The brushless type inductor type automobile current generator that the utility model provides such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4:
Fig. 1 is a brushless type inductor type automobile current generator structural representation
1 rotor, 2 stator cores, 3 stator winding (containing armature winding and excitation winding), 4 cooling fans, 5 end caps, 6 silicon rectifiers.
Fig. 2 is the rotor structure schematic diagram
7 teeth, 8 grooves.
Fig. 3 is stator core and winding schematic diagram
9 iron core vats, 10 sulculuses, 11 armature winding (three-phase or single-phase), 12 excitation winding.
Fig. 4 is the generator fundamental diagram
The load of 13 generators, 14 automatic excitation regulators, 15 drive prime mover of generator.
Generator contains stator core 2 and stator winding 3, stator core has vat 9 and sulculus 10, stator winding 3 is made up of armature winding (three-phase or single-phase) 11 and excitation winding 12, and embeds in vat and sulculus, and stator and rotor tooth, groove number and pole pair number average are by the designing requirement decision; Rotor 1 is the solid steel body or the lamination of magnetic material, has tooth 7 and groove 8 on the rotor, and by tooth, groove number form shape and size design, to obtain the armature voltage of expection, rotor does not have coil.Stator core 2 and front and rear cover 5 are fastened on the support of generator, and silicon rectifier 6 is installed in the end cap of non-shaft stretching end, and the load 13 on rectification output direct current steam supply car is as accumulator jar etc., and its positive and negative electrode wiring is identical with traditional automobile current generator.Cooling fan 4 is housed in the end cap of shaft extension end, and excitation winding 12 has been received automatic excitation regulator 14, and rotor 1 links with the prime mover 15 that drives generator.
The operation principle of generator: after this generator is supplied with the exciting current of excitation winding via field regulator 14, when rotor 1 during, be reacted to induction generation corresponding frequencies in the armature winding of stator side with n rev/min rotating speed rotation
The interchange electromotive force of (Z2 is rotor tooth or groove number in the formula), output direct current supply load 13 behind silicon rectifier, when the rotation speed change of the automobile prime mover 15 that drives generator, excitation regulation 14 is adjusted exciting current immediately, makes the direct voltage of rectifier output keep constant.
The utlity model has following advantage:
1, this generator amature is the solid steel body or is lamination, and rotor does not have coil, and is simple in structure, and parts are few, processing and fabricating is easy, and low cost of manufacture is because rotor structure is firm, even if in 12500 rev/mins of operations down at a high speed, electromechanics intensity height, resistance to shock is strong, and motor service life is long.
2, owing to brushless, eliminated operating spark, the same with claw-pole type generator, not only reduced interference, and reduced maintenance in service, recondition expense automobile mounted wireless device.
3, after this machine formally drops into batch process, be bound to be subjected to users and welcome, remarkable economic efficiency and social benefit are arranged.
