Abstract

The utility model relates to a silicon rectifying permanent-magnetic voltage regulator of a generator for vehicles. The structure of the regulator is composed of a winding 5 and an iron core generating the electromagnetic attractive force, wiring terminals 7, 8 and 9, contacts 1 and 2, insulating spacers 3 and 4, and an armature 10, the contacts 1 and 2 are opened, so the stator winding 6 of the generator is in the broken circuit, the output power to the external circuit is decreased, and the voltage drops down; when the generator is in the low rotation speed, the contacts 1 and 2 are closed to compose a return circuit of the generator winding 6, the output power to the external circuit is increased, and the voltage boosts up. Using the utility model the output voltage of the permanent-magnetic generator for vehicles can be maintained to the average stable voltage value required by the vehicle circuit.

Description

Silicon rectifying permanent-magnetic voltage regulator of generator for vehicles

The utility model relates to a kind of voltage regulating device of automobile current generator, especially the voltage regulator of permanent magnet car generator.

The structure of present known electromagnetic mechanical vibration voltage adjuster is to produce certain electromagnetic attraction by coil, being installed in the suction of coil upper contact when motor speed is high opens, make electric current reduce exciting field intensity reduction motor output end voltage by the resistance input rotor of adjuster, closing of contact exciting current increases the output voltage that improves motor when motor speed is low, and the contact reciprocating motion comes the regulator generator pressure to remain on the needs that an average burning voltage satisfies automobile circuit.But, now this adjuster of high magnetic energy neodymium iron boron generator of Ying Yonging can not adapt to, its reason is that existing Nd-Fe-B permanent-magnetic generator rotor field is constant, do not need the size of exciting current to regulate magnetic field intensity, therefore just can't control the size of the voltage of motor output end yet with the size of exciting current.

The purpose of this utility model provides a kind of a kind of adjuster with the special use of neodymium iron boron high magnetic energy permanent magnet car generator, in the size that does not need control motor output voltage under the big or small condition of exciting current.

The purpose of this utility model is to realize like this, it is improved with existing electromagnetic type mechanical oscillation adjuster, as implement illustration 1, this adjuster primary structure has the winding 5 that can produce electromagnetic attraction and iron stamen and contact 1,2 to constitute, the contact 1 of this adjuster is connected one of them winding of motor stator 6 and constitutes loops and open circuit with 2, insulating spacer 3(such as the micarex that approaches is equipped with in the iron stamen upper end regulator coil 5 in) same insulating spacer 4 is housed between binding post 7 and 8.This adjuster is equipped with 7,8,9 three binding posts, winding of 7 and 9 binding posts and motor 6 passes through formation loop, 1 and 2 contacts, binding post 8 is to be connected with the coil 5 of adjuster generation suction, its course of work is: the direct current by the silicon rectifier output when the permanent magnet generator output voltage rises to 14 volts of left and right sides increases regulator coil 5 electric currents by binding post 8, electromagnetic attraction adds to be forced contact 1 and opened in 2 minutes, alternator winding 6 opens circuit, the generator end power output is reduced, external circuit voltage descends, coil 5 electric currents reduce suction and also reduce thereupon when treating that set end voltage descends, making contact 1 and 2 closed alternator winding, 6 formation loops be defeated by " silicon bridge " exports external circuit, external circuit voltage is raise, one of them winding 6 of motor is opened circuit and closed reciprocal process makes motor output end keep an average stationary value with this, reach permanent magnet generator output voltage under different rotating speeds and maintain the required scope purpose of automobile circuit.

Owing to take such scheme, can not only can but also can pass through alternating current through this adjuster after improving at former electromagnetic type mechanical oscillation adjuster by direct current, handing over straight diverter branch only to adopt insulation spacer and increasing by two alternating current binding posts, simple in structure, be convenient to implement.

In conjunction with the accompanying drawings and embodiments the utility model is further specified.

Fig. 1 is basic structure of the present utility model and electrical schematic diagram.

Contact the 1, the 2nd with armature 10 binding posts the 7, the 9th, exchanges branch road in the circuit, it is connected with motor stator winding 6, when contact 1,2 was closed, winding 6 formed loops and produces electric currents inputs " silicon bridge ", and contact 1,2 disconnects windings 6 and can not form the loop and can not produce electric current " silicon bridge " exported.

Binding post 8 is to be connected with motor output silicon bridge to pass through R ₁, R ₂Input can produce the winding 5 of electromagnetic attraction, this part branch road is a DC circuit, for preventing the AC-DC Circuit interflow, in winding 5 iron stamens upper end insulation spacer 3 is housed, between direct current and alternating current binding post 7 and 8, also be added with same insulation spacer, be implemented on the adjuster and can control iron stamen suction in the winding 5 with this structure by direct current, contact 1 and 2 is disconnected with closed, can make alternating current that motor stator winding produces constitute the loop again and realize that motor winding 6 when the high speed do not work with opening circuit by 1 and 2 contacts, low winding 6 work of motor speed, and make the motor output voltage value of keeing relative stability satisfy the needs of automobile circuit.
