Abstract
The utility model relates to the field of the three-phase asynchronous motor technology, especially to a low-power three-phase asynchronous motor rotor. The rotor comprises a rotor body; a plurality of wire grooves are uniformly arranged at the peripheral direction of the rotor body; and the wire groove edges and the longitudinal lines of the wire grooves are mutually intersected to from included angles, wherein each of the included angles is 5 degrees to 8 degrees. When the rotor is used, the resistance of the rotor is reduced by enlarging the wire groove area, thereby ensuring the stability of the running of the low-power three-phase asynchronous motor. Meanwhile, the materials are saved and the production cost is lowered. Moreover, the provided rotor has advantages of simple structure, reasonable arrangement, and low manufacturing cost and the like.
Description
Technical field
The utility model relates to a kind of threephase asynchronous technical field, particularly a kind of small-power triphase asynchronous motor rotor.
Background technology
In the industrial and agricultural production activity, extensively adopted threephase asynchronous, and the selected motor of plant equipment that factory generally uses is all powerful motor.Therefore, the motor manufacturing is also just improved the rotor of motor in order to be adapted to client's demand with doing one's utmost, constantly optimizes the starting performance of motor.
Along with the fast development of all trades and professions, small-power triphase asynchronous motor is liked by masses also deeply; Continue to use the designing requirement of high-power electric machine rotor due to the small power motor rotor design always, semi-enclosed slot as shown in Figure 1, the both sides of its groove are set in parallel, the area of this parallel slot is less, the resistance of rotor is just larger, so just can improve the starting torque of motor, the starting performance of lifting motor; But the runnability of this small power motor is very poor, usually can not meet the demand of Client application.Therefore, how to improve the small power electric machine rotor, how to guarantee that the problems such as stable operation of small-power triphase asynchronous motor rotor have become the focus of research in the industry.
The utility model content
The purpose of this utility model is for the defective of prior art and deficiency, and small-power triphase asynchronous motor rotor a kind of simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of small-power triphase asynchronous motor rotor described in the utility model comprises rotor block, and several wire casings evenly are set on the circumferencial direction of described rotor block, and the wire casing limit of described wire casing and vertical line intersect mutually that angle, described angle are arranged is 5
0～8
0 [0006]Further, described rotor block adopts aluminium to make.
After adopting said structure, the utility model beneficial effect is: a kind of small-power triphase asynchronous motor rotor described in the utility model, comprise rotor block, several wire casings evenly are set on the circumferencial direction of described rotor block, the wire casing limit of described wire casing and vertical line intersect mutually that angle, described angle are arranged is 5
0～8
0When using the utility model, subtract trochantinian resistance by enlarging the wire casing surface area, thereby guarantee the stability of small-power triphase asynchronous motor operation, also saved material simultaneously, reduced production cost.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
Description of drawings
Fig. 1 is the structural representation of existing rotor;
Fig. 2 is structural representation of the present utility model;
Description of reference numerals:
1, rotor block; 2, wire casing; α, angle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 2, a kind of small-power triphase asynchronous motor rotor described in the utility model comprises rotor block 1, and several wire casings 2 evenly are set on the circumferencial direction of described rotor block 1, the wire casing limit of described wire casing 2 and vertical line intersect mutually angle α, and described angle α is 5
0～8
0, angle α of the present utility model is preferably 7
0So just enlarge the surface area of wire casing 2, both saved material, reduced production cost, also can reduce the resistance of rotor block 1, thereby guaranteed the stability of small-power triphase asynchronous motor operation.
Described rotor block 1 adopts aluminium to make, and has substituted copper product in the past, so both can save material cost, also can not improve the too large resistance of rotor block 1, guarantees further the stability of small-power triphase asynchronous motor operation.
When using the utility model, not only can guarantee the stability of small-power triphase asynchronous motor operation, but also can save material, reduce production costs, be convenient to promote.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
