Abstract
The utility model relates to a rotor sheet with high precision and a cooling function of a synchronous alternating-current generator, which solves the defects that the conventional generator rotor does not have an ideal heat radiation effect and cannot bring power into full play. The rotor sheet of the synchronous alternating-current generator has a simple structure and a good cooling effect. According to the rotor sheet, as a cooling air opening is arranged at the end part of a varnished wire on the basis of the conventional rotor sheet, the ventilation and heat radiation effects of the generator can be obviously improved, and the power grade of the generator is improved. The working stability and the heat radiation effect of the generator provided by the utility model are greatly improved, and the motor power is greatly improved after the rotor sheet is used.
Description
Technical field: the utility model relates to a kind of synchronous generator rotor punching, particularly relates to a kind of synchronous alternating-current generator rotor punching that has the cooling channel function.
Background technology: existing generator rotor partly is to disperse independently by four that pole piece and yoke compress with bolt, forms a rotor part.The poor stability when generator amature of this technology is worked; And radiating effect is not ideal enough; In long-term service firing process, screw will have loosening will causing between rotor and the stator to rub slightly, with badly damaged stator and rotor winding; Make the generator cisco unity malfunction, long-time use will cause burn-down of electric motor.
The utility model content: the utility model has solved the unfavorable defective of existing generator amature radiating effect, and a kind of simple in structure, good heat dissipation effect and the better synchronous alternating-current generator rotor punching of job stability are provided.
The purpose of the utility model realizes through following technical scheme: in the punching of rotor, the end that is positioned at enamelled wire is provided with cooling air port.
The utility model generator has designed four ventilation cooling vents on rotor punching, obviously improved ventilation, the radiating effect of generator.Four ventilating openings are arranged at the enamelled wire end, and the motor feels hot the most concentrated position has a rectangular shape distribution; Good heat dissipation effect; Distribute around the cooling holes, the deviation that zero gravity distributes when making working rotor and the instability of motor occurs, thus but improve the power grade of generator.The generator of the utility model has been practiced thrift the hot and stability of generator greatly, has improved the overall quality of motor.
Description of drawings: Fig. 1 is a kind of structural representation of the utility model.
Embodiment: as shown in Figure 1; The utility model be in the punching 1 of existing synchronous alternating-current generator rotor, the end that is positioned at two adjacent enamelled wires 2 is provided with cooling air port 3, the shape of cooling air port 3 distributes with the thermal source center around punching symmetrically.
As shown in Figure 1; The utility model is transformed into novel integral body with original old-fashioned split type rotor structure and shows rotor structure; In the punching of rotor, the end that is positioned at two adjacent enamelled wires 2 is provided with cooling vent 1, rotor punching is one time punching molded by silicon steel sheet, laminates into integral rotor again.
Claims (3)
1. synchronous alternating-current generator rotor punching with cooling ventilation duct, its characteristic exists: on rotor punching, be positioned at the enamelled wire end and be provided with cooling and use the air port.
2. according to claims 1 are described the synchronous alternating-current generator rotor punching that cooling channel is used is set, it is characterized in that: cooling vent is positioned at the end of two adjacent enamelled wires.
3. band cooling according to claim 2 is with the synchronous alternating-current generator rotor punching in air port, and it is characterized in that: coolant vent is arranged at around the punching, to guarantee radiating effect.
