Problems solved by technology

[0003] The purpose of the present invention is to provide a small two-pole single-phase generator rotor with non-magnetic winding pressing plate, which solves the problem of weakening the main magnetic field caused by the magnetic short circuit of the winding pressing plate in the existing small two-pole single-phase generator rotor. The load on the output of the prime mover and the excitation system must be increased, as well as the problem of large temperature rise of the rotor.

Embodiment 1

[0011] Embodiment 1: As shown in Figure 1, the small two-pole single-phase generator rotor of the present invention has an iron core 1, a winding coil 2, an insulating framework 3 and a pressing plate 4, and the winding coil 2 bypasses the insulating framework 3 and passes through the pressing plate 4 Use the bolt 5 to press tightly in the embedding groove of the iron core 1, and the material of the pressing plate 4 is stainless steel.

[0012] In order to illustrate its technical effect, the same stator is used on a small two-pole single-phase generator with an output power of 2KW, an output frequency of 50HZ, and an output voltage of 220V / 110V, and the rotor winding pressure plate 4 is made of carbon steel and stainless steel. Comparative Test. Among them, the load is a pure resistive light bulb, using the same power, the test tool is Aino 2103B electrical parameter comprehensive tester and mercury thermometer, and the test environment is indoor. The relevant parameters of ...

Embodiment 2

[0016] Embodiment 2: The structure is the same as that of Embodiment 1, except that the material of the pressing plate 4 is copper. Contrast test method, test environment, instrument used and product relevant parameter are identical with embodiment 1, and its each performance index detection result contrast is as follows:

[0017] Rotor winding pressure plate is carbon steel

Rotor winding pressure plate is stainless steel

Stator temperature rise (K)

Abstract

This invention provides one mini diode single phase generating rotor, which comprises iron core, coil set, isolation skeleton and pressure board, wherein, the set coil is through isolation skeleton through pressure board and presses the screw into the iron core imbedded tank; the pressure board is of stainless steel or of conductive metal materials. Under rotor ibis unchanged, the invention can improve the efficiency of small diode single motor to descend temperature, excitation system voltage and current.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a small-sized two-pole single-phase generator rotor. Background technique [0002] The existing small two-pole single-phase generator (1KW ~ 18KW) rotor is mainly composed of iron core, winding coil, insulating frame, pressure plate and bolts, etc., and the winding coil is pressed into the wire slot of the iron core through the pressure plate and bolts to prevent The centrifugal force generated by the high-speed rotation of the rotor and the electromagnetic force generated when the generator is working cause the field winding to fly out and be damaged. For a long time, the material of the pressure plate of the rotor winding of the engine is carbon steel. Since the carbon steel has a magnetic permeability and a large reluctance, when the generator is working, it will short-circuit part of the secondary rotating magnetic field generated by the rotor excitation windin...
