Abstract
The utility model relates to an AC motor which in specific is a totally-enclosed variable-frequency speed-adjust asynchronous motor. The utility model resolves the problem of open-type structure of current asynchronous motor that is not applicable to working condition with larger dust. The asynchronous motor comprises a frame, a stator and a rotor, wherein the frame and its two-side end caps are in enclosed structure, the stator iron core and the frame inner wall are directly contacted and fixed with each other, the frame external is provided with cooling ribs. The ratio between the sheet-punching yoke size of the stator iron core and its tooth-like part size is 0.9-1.0. The motor is designed to employ the totally-enclosed structure which is economical and solves the current motor disadvantages of open-type, easily entering dust and affecting motor lifetime, and at the same time improves the motor cooling structure which makes the motor with the closed state well implement cooling. The motor is applicable to work condition with larger dust and particularly ten cubic meters alterative-current excavator as a running motor.
Description
Technical field
The utility model relates to alternating current machine, particularly is applied in to exchange on the excavator as the variable-frequency control asynchronous motor of running motor, is specially a kind of totally-enclosed variable-frequency control asynchronous motor.
Background technology
10 cubic metres of excavators that exchange transmission belong to the domestic great equipment of developing first, before this, this type of equips long-term dependence on import China, the domestic processing of having only minority enterprise can finish the part mechanical part, complete machine all is to be finished by overseas enterprise, the moving part of core technology fax become the restraining factors that restriction China develops this type of equipment, and the traveling asynchronous motor is the moving important component part of fax by external directly control.Existing asynchronous motor is for realizing air cooling, (being that casing does not seal) of open type normally, and 10 cubes of excavator running motors are operated under the big operational environment of mining dust, open-type electric machine easily advances dust, influences the drawback of electrical machinery life.
Summary of the invention
It is the open type structure that the utility model solves existing asynchronous motor, is not suitable for the problem of the bigger operational environment of dust, and a kind of totally-enclosed variable-frequency control asynchronous motor is provided.
The utility model is to adopt following technical scheme to realize: totally-enclosed variable-frequency control asynchronous motor, comprise support, stator and rotor, support and end covers at two sides thereof are enclosed construction (being not have ventilation hole on support and the end cap), stator core is fixed (being not stay vent passages between stator core and the inboard wall of base) with inboard wall of base for directly contacting, the heat of being convenient to produce when motor moved directly is passed to support, base outer is provided with radiating ribs, to strengthen the heat-sinking capability of support.
For further improving the heat-sinking capability of motor under closed state, the ratio of stator iron-core lamination yoke size and tooth portion size is 0.9-1.0 (non-sealing motor is generally 0.75), like this, the distribution of motor magnetic loading is stressed in stator yoke portion, the magnetic loading that is stator yoke portion is higher, and stator teeth is lower, the heat of generation is well distributed by support, rather than accumulate near the groove.
Motor described in the utility model adopts full-closed structure (not being with blower fan) when design, not only economy but also solved existing motor open type, easily advance dust, influence the drawback of electrical machinery life, improved the cooling structure of motor simultaneously, made motor under closed state, can realize cooling well.This motor is applicable to the operational environment that dust is bigger, is specially adapted to 10 cubic metres of running motors in the excavator that exchanges transmissions.
