Abstract
A tangential rotor of a rotary motor comprises a rotating shaft and a rotor formed by laminated iron cores. The laminated iron cores are equipped with a plurality of permanent magnet pole portions that rotate around the axis of the rotating shaft and magnetize in a circumferential manner around the rotor corresponding to the axis. The permanent magnet pole portions are embedded in the laminated iron cores through permanent magnet grooves. One side of each permanent magnet groove, close to an air gap, is connected or disconnected with each laminated iron core. A distance between every two adjacent permanent magnet grooves close to one side of the rotating shaft is 0.1-5 millimeters in circumferential width. Every two adjacent permanent magnet pole portions are opposite in polarity. A distance between every two adjacent permanent magnet grooves close to one side of the rotating shaft is 0.4-3 millimeters in circumferential width. According to the tangential rotor, the laminated iron cores are provided with the permanent magnet grooves used for embedding the permanent magnet pole portions, and the adjacent permanent magnet pole portions are opposite in polarity. The tangential rotor of a rotary motor is simple and reasonable in structure, allows magnetic leakage of a magnet to be minimized, enables the utilization rate of the magnet to be increased, helps to solve problems that the rotating shaft needs a stainless steel material or a magnet shield copper sleeve, and enables manufacture costs to be effectively reduced.
Description
Technical field
The utility model relates to a kind of electric rotating machine, specifically is a kind of tangential rotor of electric rotating machine.
Background technology
In the prior art, the every utmost point magnetic flux of circumferential magnetization flush type magneto is provided by two permanent magnet parallel connections, has improved the magnetic flux density in the stator and rotor intermediate air gap effectively, and then has increased the output of motor, and is as shown in Figure 1; Yet its bottom permanent magnet utilance is low, and leakage field is abundant, and rotating shaft often needs stainless steel material, perhaps adopts at a distance from the magnetic copper sheathing, and as shown in Figure 2, cost is very high, has influenced the application of this construction rotor.
The utility model content
The purpose of the utility model aims to provide the tangential rotor of the electric rotating machine of a kind of simplicity of design, rational in infrastructure, low cost of manufacture, to overcome weak point of the prior art.
Press the tangential rotor of a kind of electric rotating machine of this purpose design; Comprise the rotor that constitutes by rotating shaft and laminate core; Be provided with in the laminate core along the rotation of the axis of rotating shaft and relatively this axis along magnetized several permanent-magnet pole portions of periphery of rotor; Its architectural feature is that permanent-magnet pole portion is embedded in the laminate core through permanent magnet trough, and nearly air gap one side of said permanent magnet trough is connected with laminate core or breaks off, and the circumferential width at the interval that its nearly rotating shaft one side is mutual is the 0.1-5 millimeter.
The polarity of said adjacent permanent-magnet pole portion is opposite.
The circumferential width at the interval that nearly rotating shaft one side of said permanent magnet trough is mutual is the 0.4-3 millimeter.
The utility model is provided for the permanent magnet trough of embedding permanent-magnet pole portion on laminate core; The polarity of adjacent permanent-magnet pole portion is opposite; It is simple and reasonable, can reduce magnet leakage field phenomenon, and it is low to improve the magnet utilance; Solve the problem that rotating shaft need be used stainless steel material or separated magnetic copper sheathing, effectively reduce cost of manufacture.

Fig. 1 is the structural representation of prior art one flush type permanent magnet machine rotor.
Fig. 2 is the structural representation of the another flush type permanent magnet machine rotor of prior art.
Fig. 3 is the stereogram of the utility model one embodiment.
Fig. 4 is the front view of the another embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
First embodiment
Referring to Fig. 3; The tangential rotor of this electric rotating machine; Comprise the rotor that constitutes by rotating shaft 3 and laminate core 2, be provided with along the axis rotation of rotating shaft 3 in the laminate core 2 and this axis is along magnetized several permanent-magnet pole portions 5 of periphery of rotor relatively that its permanent-magnet pole portion 5 is embedded in the laminate core 2 through permanent magnet trough 4; Said permanent magnet trough 4 nearly air gap one sides are connected with laminate core 2 or break off, and the circumferential width at the interval 6 that its nearly rotating shaft one side is mutual is the 0.1-5 millimeter.
In the present embodiment, this rotor is 10 utmost point rotors, totally 10 in permanent-magnet pole portion 5, and nearly air gap one sides 7 of permanent magnet trough 4 are broken off with laminate core 2, and the polarity of adjacent permanent-magnet pole portion 5 is opposite.Have the space between permanent magnet trough 4 nearly rotating shaft one sides and the permanent-magnet pole portion 5, and the circumferential width at the mutual interval 6 of permanent magnet trough 4 nearly rotating shaft one sides is the 0.4-3 millimeter, further is preferably 0.5 millimeter, 1 millimeter, 1.5 millimeters, 2 millimeters, 2.5 millimeters.
Second embodiment
Referring to Fig. 4, the tangential rotor of this electric rotating machine, its main distinction with first embodiment is that said permanent magnet trough 4 nearly air gap one sides 7 are connected with laminate core 2.Other do not state part, with first embodiment, no longer repeat.
Claims (3)
1. the tangential rotor of an electric rotating machine; Comprise the rotor that constitutes by rotating shaft (3) and laminate core (2); Be provided with in the laminate core (2) along the rotation of the axis of rotating shaft (3) and relatively this axis along magnetized several permanent-magnet pole portions (5) of periphery of rotor; It is characterized in that permanent-magnet pole portion (5) is embedded in the laminate core (2) through permanent magnet trough (4), nearly air gap one side of said permanent magnet trough (4) is connected with laminate core (2) or breaks off, and the circumferential width at the interval (6) that its nearly rotating shaft one side is mutual is the 0.1-5 millimeter.
2. according to the tangential rotor of the said electric rotating machine of claim 1, it is characterized in that the polarity of said adjacent permanent-magnet pole portion (5) is opposite.
