Abstract
The utility model relates to a rotor punching sheet used for a high-voltage motor. The rotor punching sheet comprises a rotor punching sheet body. 86 rotor punching sheet grooves are disposed on the rotor punching sheet body and are uniformly distributed. A notch of each rotor punching sheet groove is 3.5mm in width b and 7.3mm in height h. Each rotor punching sheet groove is 6.3mm in width B and 56.2mm in height H. The rotor punching sheet has a compact and reasonable structure, is simple to machine, and is short in machining period, low in cost and high in work efficiency. The rotor punching sheet helps to effectively control defects of high electromagnetic noise, high starting current, high temperature rise or the like. Therefore, the rotor punching sheet can be widely applied to a rotor iron core of a 6000V motor with the height of center of Y2-HV560-8-1120KW.
Description
Technical field
The utility model relates to a kind of high-voltage motor rotor punching, specifically is used for the rotor core of high-pressure efficient motor Y2-HV 560-8-1120KW 6000V.
Background technology
Rotor punching is the key components and parts in the motor, its material, inner circle size, excircle dimension, flute profile size, flute profile what etc. the efficient of motor is had direct impact.And use in the market maximum Y-series rotor grooves to cooperate, can't reach center high 560-1120KW motor, and realize that in long-term use procedure also there are the defectives such as electromagnetic noise is large, starting current is large, temperature rise is high in it.
In prior art, domestic 1120KW high-voltage motor that can't the high 560mm in the production center all is by import ABB AB, Siemens Company usually; But center high 560-1120KW motor is widely used in the motor in the fields such as industry, agricultural, commerce, building industry and traffic at present.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby the high-voltage motor rotor punching of the high 560-1120KW in a kind of center is provided, and this rotor punching processing is simple, the process-cycle is short, cost is low, high efficiency; Can effectively control the defectives such as electromagnetic noise is large, starting current is large, temperature rise is high.
According to the technical scheme that the utility model provides, a kind of high-voltage motor comprises the rotor punching body with rotor punching, and described rotor punching body is provided with 86 rotor punching grooves, and the rotor punching groove evenly distributes.
Flute profile slot opening b is 3.5mm in the described rotor punching groove, and the high h of flute profile notch is 7.3mm, and the wide B of flute profile is 6.3mm, and the high H of flute profile is 56.2mm.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, reasonable, processing is simple, the process-cycle is short, cost is low, high efficiency; Can effectively control the defectives such as electromagnetic noise is large, starting current is large, temperature rise is high; The center that can be widely used in is high in the rotor core of Y2-HV 560-8-1120KW 6000V pole motor.
