Description
Technical Field
The utility model relates to a stator core structure of a synchronous diesel generator.
Background
The motor can generate loss in the running process, and the loss is converted into heat in the motor, so that the temperature of each part in the motor is increased, the high power density inevitably increases the heating of the unit volume when the motor runs, and the temperature rise of key parts such as a motor winding, an iron core and the like is increased. In order to ensure stable and safe operation of the motor, the temperature rise of the motor cannot exceed a certain value, and a reasonable cooling system is very important to control the temperature rise of the motor.
In a conventional high-power density motor, a water jacket base or a tube penetrating through the yoke of an iron core is adopted to cool the motor, heat generated by a stator winding is required to be firstly transferred to the yoke and the tooth of the stator core in a radial and circumferential mode through heat conduction, and then is transferred to the water jacket base or a water tube of the stator yoke by the stator core to be taken away by cooling water. The disadvantage of this cooling method is that the heat source is far from the cold source, the heat conduction path is long, and the cooling problem of the motor rotor cannot be solved, so that the cooling effect is limited, and the improvement of the motor power density is limited.
Disclosure of Invention
The stator core structure of the synchronous diesel generator is simple in structure, novel and reasonable in design and good in using effect, and the problems that in the prior art, cooling effect is poor, power density is limited and the like are solved. The technical scheme of the utility model is as follows: a stator core structure of a synchronous diesel generator is characterized in that insulation tensioning screw rods (3) penetrate through a plurality of groups of stator punching sheets (1), stator pressing rings (2) are sleeved at two ends of each insulation tensioning screw rod (3), insulation washers (6) and washers (5) are sequentially sleeved on the insulation tensioning screw rods (3) in the pressing rings (2), and nuts (4) are assembled at two ends of each insulation tensioning screw rod (3).
Each stator punching sheet (1) is provided with a round hole (7) for axial ventilation and cooling, and each stator punching sheet (1) is provided with a groove (8) for embedding a stator coil.
The stator punching sheet is fixedly connected with the stator pressing rings arranged at the two ends of the stator iron core through 8 insulating tensioning screws, nuts, washers and insulating washers, so that a certain iron core pressing force is ensured.
Through the axial ventilation holes on the stator punching sheet, the cooling of the stator core is realized under the action of the coaxial fan.
The utility model has advanced and reasonable structural design, easy installation and good ventilation and cooling effects.
