Abstract
The utility model discloses a high efficiency heat radiation motor, which comprises a stator, a rotor, a front end cover and a rear end cover, the rotor is arranged in the stator, the front end of the stator is limited on the front end cover, the rear end of the stator is limited on the rear end cover, the outer wall of the intermediate segment of the stator is exposed between the front end cover and the rear end cover, the front end cover is fixedly connected to the rear end cover; at least four projections are arranged on the end cover, the projections are uniformly distributed on the end cover, the projection is clamped with the stator for connecting, the end cover comprises an end plate, a mounting base and a bearing chamber, the bearing chamber is positioned at the center of the end plate, the end plate, the mounting base and the bearing chamber are formed as one body, the structure is simple and reasonable, the usage is convenient, the work is stable, the heat can be timely led out, and the heat radiation effect is substantial.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of high efficiency and heat radiation motor.
Background technology
The motor of prior art comprises stator, rotor, shell, front end housing and rear end cap.Described stator and rotor are installed in the described shell, and described front end housing is fixed on the front end of described shell, and described rear end cap is fixed on the rear end of described shell.There is following defective in the motor of this kind prior art: because stator and rotor are installed in the enclosure, so that the radiating effect of motor is bad, generation can motor damage when serious causes the accident, motor is electronic product common in industrial production and the daily life, in electric machine structure, stator, rotor, end cap are the three large parts that form motor, and end cap can be divided into: cast iron end cap, aluminium die casting end cap, thin plate stretching end cap etc. form, and aluminium die casting end cap is current mode relatively more commonly used.Existing end cap substantially all is to have a monolithic case, then is provided with some through holes at shell.Because adopt monoblock cast, so that end cap easily is out of shape, when end cover body was connected with bearing pedestal, concentricity can not be guaranteed, radiating effect is poor, and temperature rise is higher, and the use aluminum is more, and cost is relatively high, so there is defective in prior art, needs improvement.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple and reasonable for structure, easy to use for overcoming weak point of the prior art, and working stability is in time derived heat, the significant high efficiency and heat radiation motor of radiating effect.
For solving technical problem of the present utility model, the technical scheme that adopts is: a kind of high efficiency and heat radiation motor, comprise stator, rotor, front end housing, rear end cap, described rotor is arranged in the stator, described stator front end is spacing on described front end housing, described stator rear end is spacing on described rear end cap, and the outer wall in described stator stage casing reveals to be put between front end housing and rear end cap, and described front end housing is fixedly connected with rear end cap; At least be provided with 4 projections on the described end cap, described projection is uniformly distributed on the end cap, described projection and stator engagement connection, and described end cap comprises end plate, holder, bearing chamber, described bearing chamber is positioned at the end plate center, and described end plate, holder and bearing chamber are one-body molded;
Connect by circumferential reinforcement between the described holder, be connected by shaft orientation reinforcing rib between described end plate and the holder;
Be bolted to connection between described front end housing and the rear end cap.
Beneficial effect with respect to prior art is, the front end housing of motor and rear end cap are fixedly connected with and the outer wall dew in described stator stage casing is put between front end housing and rear end cap, save shell, improved the radiating effect of motor, avoided the motor damage because heat radiation is bad; Be bolted to connection between front end housing and the rear end cap, simple in structure, easily realize.
Description of drawings
Fig. 1 is basic structure schematic diagram of the present utility model;
Fig. 2 is the utility model end cover structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing optimal way of the present utility model is described in further detail.
As shown in Figure 1 and Figure 2, this high efficiency and heat radiation electric machine structure is simple, reasonable, and easy to use, working stability is in time derived heat, and radiating effect is remarkable.This high efficiency and heat radiation motor, comprise stator 5, rotor 1, front end housing 2, rear end cap 6, described rotor 1 is arranged in the stator 5, described stator 5 front ends are spacing on described front end housing 2, described stator 5 rear ends are spacing on described rear end cap 6, the outer wall in described stator 5 stage casings reveals to be put between front end housing 2 and rear end cap 6, and described front end housing 2 is fixedly connected with rear end cap 6; Be fixedly connected with by bolt 3 between described front end housing 2 and the rear end cap 6, saved shell, improved the radiating effect of motor, avoid easily realizing because heat radiation is bad and motor damage is simple in structure;
At least be provided with 4 projections 4 on the described end cap, described protruding 4 are uniformly distributed on the end cap, described protruding 4 with stator 5 engagement connections, described end cap comprises end plate 9, holder 8, bearing chamber 11, described bearing chamber 11 is positioned at end plate 9 centers, connect by circumferential reinforcement 7 between the described holder 8, be connected by shaft orientation reinforcing rib 12 between described end plate 9 and the holder 8; Described end plate 9, holder 8 and bearing chamber 11 are one-body molded, have alleviated motor weight, and be economical and practical.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
