Abstract
A novel motor relates to the improvement of a motor structure. The novel motor consists of a rear fan wheel, a rear end cover assembly, a stator shell assembly, a rotor assembly, a connection screw rod, a front end cover, a front fan wheel and an output belt pulley. The rotor assembly is arranged in the stator shell assembly, the front end cover is arranged at the front side of the rotor assembly, the rear end cover assembly is arranged at the rear side of the rotor assembly, and the front end cover, the stator shell assembly and the rear end cover assembly are fixedly connected by the connection screw rod. The front fan wheel is arranged at the front side of the front end cover and is arranged at a front end shaft of the rotor assembly, and the output belt pulley is further arranged at the front side of the front fan wheel and also arranged on the front end shaft of the rotor assembly. The rear fan wheel is arranged at the rear side of the rear end cover assembly and also arranged at a rear end shaft of the rotor assembly. The novel motor solves the problem that the ventilation volume of the prior motor is not enough.

The utility model content
The purpose of this utility model provides a kind of New-type electric machine, and the utility model has solved the not enough problem of existing motor ventilation amount.
The utility model New-type electric machine is made of after wind impeller 1, rear end cap assembly 2, stator case assembly 3, rotor assembly 4, connecting screw rod 5, front end housing 6, forefan wheel 7 and output belt pulley 8; Rotor assembly 4 is arranged at stator case assembly 3 inside, and front end housing 6 is installed in rotor assembly 4 front sides, and rear end cap assembly 2 is installed in rotor assembly 4 rear sides, and front end housing 6, stator case assembly 3, rear end cap assembly 2 is fixedly connected by connecting screw rod 5; Forefan wheel 7 is positioned at front end housing 6 front sides, and forefan wheel 7 is installed on the rotor assembly 4 front end axles, takes turns 7 front sides at forefan and also is provided with output belt pulley 8, and output belt pulley 8 is installed on the front end axle of rotor assembly 4; Be provided with after wind impeller 1 at rear end cap assembly 2 rear sides, after wind impeller 1 is installed on the rear end axle of rotor assembly 4.
The utility model New-type electric machine has increased the ventilation quantity of motor interior; Reduced the temperature of motor interior; A lot of incipient faults have been eliminated; Improved the operating efficiency of motor; Prolonged the life-span of motor.
Description of drawings
Fig. 1 is the utility model parts expanded views.
Symbol description among the figure: after wind impeller 1, rear end cap assembly 2, stator case assembly 3, rotor assembly 4, connecting screw rod 5, front end housing 6, forefan wheel 7, output belt pulley 8.
Embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Consult Fig. 1, New-type electric machine is made of after wind impeller 1, rear end cap assembly 2, stator case assembly 3, rotor assembly 4, connecting screw rod 5, front end housing 6, forefan wheel 7 and output belt pulley 8; Rotor assembly 4 is arranged at stator case assembly 3 inside, and front end housing 6 is installed in rotor assembly 4 front sides, and rear end cap assembly 2 is installed in rotor assembly 4 rear sides, and front end housing 6, stator case assembly 3, rear end cap assembly 2 is fixedly connected by connecting screw rod 5; Forefan wheel 7 is positioned at front end housing 6 front sides, and forefan wheel 7 is installed on the rotor assembly 4 front end axles, takes turns 7 front sides at forefan and also is provided with output belt pulley 8, and output belt pulley 8 is installed on the front end axle of rotor assembly 4; Be provided with after wind impeller 1 at rear end cap assembly 2 rear sides, after wind impeller 1 is installed on the rear end axle of rotor assembly 4.
The utility model improves in the design of motor according to the defective of prior art.Front end at motor is installed fan wheel, and fan wheel can adopt centrifugal operation principle, the hot-air of motor interior is discharged from inside to outside reasonable in design.
This motor adopts the operation principle of air cooling.Forefan adopts centrifugal, and the after wind impeller adopts the turbine propulsion formula.The forefan wheel is installed on the belt pulley, can guarantee the smooth and easy of circulation of air.And belt pulley is installed on the motor output main shaft, the after wind impeller is installed on the main shaft of the motor other end, main shaft drives forward and backward fan wheel running during running, forward and backward fan wheel is started working in operation process, the after wind impeller constantly advances the outer cold air of machine by the past motor of the air inlet of rear end cap the inside, and the forefan wheel is under action of centrifugal force, constantly the motor interior hot-air is discharged toward the outside through the protecgulum air outlet, thereby reach the requirement that reduces the motor interior temperature
Above embodiment is more preferably embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection range of the present utility model.
