Description

Domestic single phase generator

The utility model is to belong to a kind of low capacity family expenses single-phase generator.

At present, existing low capacity single-phase generator on market, generally all be by support, stator core, the stator master, pay winding, rotor core, rotor is paid the magnetic winding, collector ring, carbon brush, carbon brush holder, brush holder spring, the rotor arbor, front and rear cover, front and back bearings, the front and back bearings lid, cooling fan blade, compositions such as blade cover, its carbon brush, carbon brush holder, the existence of brush holder spring and rotor current collector ring etc., daily operation and maintenance are brought a lot of inconvenience: also have a kind of collector ring that do not have, the single-phase generator of carbon brush holder etc., an its stator main winding and a pair winding are synchronous, that is to say, pay winding tap from main winding and obtain, pay in the winding circuit and be connected to a plurality of capacitors; Rotor core has two concentric windings, one is the feedback winding, one is field winding, and in the feedback winding circuit, be equipped with 4 rectifier diodes, field winding, feedback winding phase place mutual deviation 90 degree, this generator voltage when bringing onto load is very unstable, particularly be with inductive load, the voltage undulation of this generator is bigger, sometimes even all to smash.

The utility model provides the small-sized single-phase generator that a kind of electric property is stable, simple in structure, do not have collector ring, carbon brush, carbon brush holder.

The utility model is achieved in that in motor stator core a concentric main winding in single-phase the two poles of the earth of design and single-phase the two poles of the earth pay winding with one heart, main, pay winding circle mutual deviation 90 degree in stator, incorporate an AC capacitor at the two ends of paying the winding lead-out wire, rotor core, design a concentric winding in single-phase the two poles of the earth, the rotor magnetic pole number is the same with the number of magnetic poles of stator, in the every utmost point winding of rotor, all seal in a silicon rectifier diode by right-hand screw rule, a resistor, the stator main winding of inserting in parallel at the two ends of rectifier diode, pay winding, the rotor winding is all selected the high strength enamelled wire coiling for use.

Family expenses single-phase generator of the present utility model, volume is little, in light weight, and is simple in structure, good electric property, the inductive load starting capability is good, and it is good to encourage performance automatically by force.

Fig. 3 is single-phase generator rotor developed winding diagram and circuit interconnect pattern.

Further describe below in conjunction with accompanying drawing:

The stator core of generator is fixed on the support, and stator main winding (1) on the stator core and stator are paid winding (6) at space mutual deviation 90 degree, and the every extremely every circle limit number of turn and the winding pitch of main winding (1) are respectively: from minimum pitch is 1-4 groove 15 circles; 2-6 groove 29 circles; 3-8 groove 29 circles; 4-10 groove 29 circles; 5-12 groove 29 circles; The line of main winding directly is the high strength enamelled wire coiling with 1.16 millimeters of φ, and the number of turn and the winding pitch on pair every extremely every circle of winding (6) limit are respectively: from minimum pitch 1-10 groove 42 circles, and 2-12 groove 85 circles; Line is directly selected the high strength enamelled wire coiling of 0.69 millimeter of φ for use, the rotor field winding (3) of the rotor core (4) of AC capacitor (7) on the rotor arbor of a 15uF/400VAC is inserted at the two ends of paying winding (6) lead-out wire, and the number of turn and the winding pitch on every extremely every circle limit of rotor winding are: from minimum pitch 1-3 groove 35 circles; 3-7 groove 48 circles; 4-9 groove 48 circles; 5-11 groove 48 circles; Line is directly selected the high strength enamelled wire system of 0.69 millimeter of φ for use, and every utmost point winding of rotor all seals in the silicon rectifier diode (2) of a 3-5A/400V respectively by right-hand screw rule, incorporates the resistor (5) of one 1/4 watt 15K again at the two ends of diode.
