Abstract
The utility model discloses a micro gap electric motor which comprises a stator and a rotor. The gap between the working planes of the stator and the rotor is less than 0.05mm. The stator and the rotor are pressed by a pressing device; the working planes of the stator and the rotor are jointed. The electric motor may be a linear electric motor, a plate-shaped electric motor, a bowl-shaped electric motor or an electric motor of any shape. With the decrease of the length of the gap, in the condition of the same output power, the utility model is of obvious reduction in power consumption compared with a common electric motor, thereby improving efficiency of the electric motor and solving the problem of large gap of the prior bowl-shaped electric motor or the linear electric motor. The micro gap electric motor is mainly applicable to the linear electric motor, the plate-shaped electric motor or the bowl-shaped electric motor.
Description
(1) technical field:
The utility model relates to a kind of motor, particularly a kind of little air gap motor.
(2) background technology:
Existing traditional all kinds of electric rotating machines or linear electric motors all have magnetic resistance.Mainly on the air gap of motor, air gap is excessive for the magnetic resistance of motor, and then magnetic resistance increases, and excitation loss is big, and exciting current strengthens, and power factor (PF) descends.In experiment even with magnetic fluid technique, eliminate air gap, but the durable degree and the sealing problem of magnetic fluid, still being difficult to cheaply so far, cost solves.
(3) utility model content:
The purpose of this utility model provides a kind of little air gap motor that can address the above problem and be applicable to bowl-type, dish type or linear electric motors.
The utility model designs a kind of little air gap motor, and the stator and the rotor of motor are compressed by hold down gag, and the air gap between the stator of motor and the working face of rotor is preferably fitted between the stator of motor and the working face of rotor less than 0.05mm, does not have air gap fully.The working face air gap of stator and rotor is less than 0.05mm or go to zero, and makes between the working face of motor almost to fit mutually, and the air gap of motor is very little almost nil, has reduced the loss of exciting current, has improved the power factor of motor.This little air gap motor is linear electric motors, disc-type machine or bowl-type motor, and the working face of linear electric motors, disc-type machine or bowl-type motor is open, therefore the problem that can not sweep thorax.
The little air gap motor advantage of the utility model is: the air gap between the stator of motor and the working face of rotor is fitted through stator after the machine operation and rotor mutually less than 0.05mm, and the air gap that obtains motor is almost nil.Almost fit between the stator of motor and the working face of rotor, the loss of exciting current is little, and therefore, under the situation of same power output, motor power consumption obviously descends, the electric efficiency height.
(4) description of drawings:
Fig. 1 is the side cutaway view of these little air gap motor linear electric motors;
Fig. 2 is the side cutaway view of this little air gap motor bowl-type motor;
Fig. 3 is the stereogram of this little air gap motor disc-type machine.
Reference numeral: rotor 1, stator 2, air gap 3.
(5) embodiment:
As Fig. 1 is the linear electric motors side cutaway view of this little air gap motor embodiment, and after the stator 2 of motor and rotor 1 assembling finished, the air gap 3 between the working face of its stator 2 and rotor 1 was 0.05mm.
As Fig. 2 is the bowl-type motor side pseudosection of this little air gap motor embodiment, after the stator 2 of motor and rotor 1 assembling finish, compress by hold down gag, in the mutual break-in of process external force, fit between the working face of its stator 2 and rotor 1, do not have air gap between the working face of stator 2 and rotor 1.
As Fig. 3 is the disc-type machine side cutaway view of this little air gap motor embodiment, after the stator 2 of motor and rotor assembling finish, fits between the working face of its stator 2 and rotor 1, does not have air gap between the working face of stator 2 and rotor 1.
Claims (4)
1. little air gap motor comprises stator and rotor, it is characterized in that: the air gap (3) between the working face of stator of motor (2) and rotor (1) is less than 0.05mm.
