Abstract
The utility model discloses a motor which comprises a front end cover, a rear end cover, a stator and a rotor. The rotor is arranged in the stator. The front end of the stator is fixed on the front end cover. The rear end of the stator is fixed on the rear end cover. The outer wall of the stator is exposed between the front end cover and the rear end cover. Both ends of the rotor are provided with rotor fan blades. The front end and the rear end of a rotation shaft of the rotor respectively stretch out from the front end cover and the rear end cover. The rear end of the rotation shaft is fixedly connected with a cooling fan blade. According to the utility model, the outer wall of the stator is exposed between the front end cover and the rear end cover; both ends of the rotor are provided with the rotor fan blades; the rear end of the rotation shaft is provided with the cooling fan blade; parts of a casing are eliminated; compared with the prior art, the radiating effect of the motor is improved; the motor performance is stabilized; and the problem that the motor is burnt out, which is caused by poor radiating, is avoided.
Description
Technical field
The utility model relates to a kind of motor.
Background technology
The motor of prior art comprises stator, rotor, shell, front end housing and rear end cap.Stator and rotor are installed in the enclosure, and front end housing is fixed on the front end of shell, and rear end cap is fixed on the rear end of shell.There is following defective in this motor: because stator and rotor are installed in the enclosure, so that the radiating effect of motor is bad, cause motor performance unstable, generation can motor damage when serious causes the accident.
The utility model content
The purpose of this utility model is to provide a kind of radiating effect better for above-mentioned the deficiencies in the prior art, the motor that performance is more stable.
For achieving the above object, the technical solution of the utility model is: a kind of motor, comprise front end housing, rear end cap and stator and rotor, described rotor is installed in the stator, the front end of described stator is fixed on the front end housing, the rear end of stator is fixed on the rear end cap, and the outer wall of described stator exposes between front end housing and rear end cap; The two ends of described rotor are provided with the rotor fan blade, and stretch out from described front end housing, rear end cap respectively rotating shaft front end, the rear end of rotor, is fixedly connected with cooling fan blade on the rear end of rotating shaft.
As the further setting of such scheme, the two ends of described rotor are provided with end ring, and rotor fan blade and end ring are one-body molded.
As the further setting of such scheme, described front end housing, stator and rear end cap three are fixing by being spirally connected.
The beneficial effects of the utility model are: owing to having adopted the outer wall of stator to expose between front end housing and rear end cap, the rotor fan blade is set two ends of rotor and the rotating shaft rear end arranges the cooling air leaf structure, the parts of shell have been saved, compared with prior art, improved the radiating effect of motor, stablize motor performance, avoided the motor damage because heat radiation is bad.
