Embodiment Construction

[0008] Such as figure 1 As shown, in order to be more clear, it will be further explained in conjunction with specific embodiments, a single-pivot electric up-frequency generator, its power frequency (50HZ) 2-pole asynchronous motor and intermediate frequency (397HZ) 16-pole synchronous generator common rotor iron core The rotor punching diagram is attached.

[0009] Insert 32 brass round rods into 32 small round holes 1, 16 round copper rods into 16 small round holes 2, and 16 rectangular red copper rods into 16 shovel-shaped slots 4. These conductors are firmly welded to the copper plates at both ends of the rotor core to form a three-layer squirrel cage. When the asynchronous motor is started, the resistance is required to be relatively large. At this time, the squirrel cages in the 32 small round holes 1 are made of brass, and the resistivity Larger, so the resistance is larger, and the copper rods (rods) of the other 16 small round holes 2 and 16 shovel-shaped grooves 4 ...

Abstract

The invention relates to a rotor sheet of a single pivot electric generator with electric frequency raising, and is characterized in that 16 rectangular channels and 16 spade channels are punched on the rotor sheet to form 16 teeth, namely 16 salient poles, wherein two ringent small circular holes and one circular hole are punched on each pole, and an inner hole provided with a keyslot is punched on the rotor sheet. The rotor sheet has the technical effects that: 1. iron rotor cores formed by overlapping the rotor sheets can form a three-layer rotor cages, the asynchronous starting torque is large, and an asynchronous motor has stable running and low slip ratio and speed fluctuation; 2. the rotor cage rotor can also be used as a full damping system of an intermediate synchronization generator, thereby improving the voltage waveform and increasing the non-linear load capacity; and 3. the ventilation of axial through holes is favorable, the temperature rise is low, and the reliability is high.

Description

technical field [0001] The invention relates to a single-pivot type electric up-frequency generator, in particular to a rotor plate of the single-pivot type electric up-frequency generator. Background technique [0002] During the working process of the single-pivot asynchronous electric frequency converter, there are small starting torque, large speed fluctuation, large slip rate, and poor power generation quality of the intermediate frequency generator. One of the main reasons is that the rotor plate design of this structure motor is often It is the result of simple composite design of ordinary squirrel-cage asynchronous motor and ordinary salient pole generator. In view of the above situation, the structure of the rotor punch must be improved in order to increase the asynchronous starting torque, reduce the speed fluctuation, reduce the slip rate, and ensure the power supply quality of the intermediate frequency AC. Contents of the invention [0003] The purpose of the...
