Abstract
A radial 24-pole ultra-low speed permanent magnet synchronous motor comprises a wound stator and a rotor. The rotor is arranged in the stator through a casing. The rotor is a squirrel case rotor with squirrel cage bars arranged on the outer circumference, the squirrel cage bars are embedded in squirrel cage bar grooves, V-shaped magnet grooves are arranged on the periphery of the central shaft of the rotor, permanent magnets are arranged inside the V-shaped magnet grooves, and fixing holes are arranged between the V-shaped magnet grooves. Two ends of the rotor are provided with retaining disks, and bolts penetrate the fixing holes to fix the retaining disks at the ends of the rotor. The radial 24-pole ultra-low speed permanent magnet synchronous motor has the advantages that a traditional 8-pole motor is replaced. The radial 24-pole ultra-low speed permanent magnet synchronous motor is used for oil wells with a block coefficient smaller than 0.3, the block coefficient is increased by around 3 times, and the power saving rate of a single oil well reaches 50% or so.
Description
Technical field
The utility model relates to a kind of synchronous motor, is specifically related to a kind of radial 24 utmost point Ultra-Low Speed permanent magnet synchronous motors.
Background technology
In recent years, along with the passing of oil exploitation time, stripper increasing day by day, and these aboveground motor of oil extractor major parts still adopt the asynchronous motor of 8 utmost points, and this class motor causes the oil pump coefficient of fullness to descend, and the power consumption of specific yield increases.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of radial 24 utmost point Ultra-Low Speed permanent magnet synchronous motors are provided.
Its technical scheme is: comprise stator and rotor, described stator is the Wound-rotor type stator, and rotor is installed in the stator by shell.Described rotor is the cage rotor that excircle is provided with squirrel-cage bar, and squirrel-cage bar is embedded in the squirrel-cage bar groove, and its central shaft outer periphery has the magnet slot of V word shape, is inlaid with permanent magnet in this V word shape magnet slot, is provided with fixing hole in the middle of it; Described two ends of rotor is provided with block plate, and block plate passes fixing hole by bolt and is fixed on rotor tip.
Wherein, the magnet slot of described V word shape and be embedded in its inner permanent magnet and all be made as 24 groups, and be evenly distributed on rotor center axle periphery.
Effect intentionally of the present utility model is the motor that substitutes existing oil well 8 utmost points, solves the oil well of pump coefficient of fullness below 0.3, and coefficient of fullness improves about 3 times, and single port oil well power saving rate can reach about 50%.
