Abstract
The utility model discloses a self-adjusting speed motor for special use, which belongs to the technical field of motors. The utility model comprises a magnetic shunt mechanism which is composed of a stator which can shift on axial direction, a squirrel-cage type main rotor, and a circular ring iron core whose diameter is similar to the outer diameter of the rotor. The utility model has the advantages that the manufacturing technique is simple; the rotor inertia drops down; requirement to the coaxiality is not high; the effect of energy saving is obvious.
Description
The utility model belongs to technical field of motors.Further relate to a kind of asynchronous motor from the speed governing motor special.
Domestic, mobile stator stepless speed regulation induction motor, for example utility model 92205949.7 and 92234989.4 is the composite rotors induction motor, stator can move axially, with the coupling ratio of change stator with main rotor, reach the speed governing purpose, this kind structure is complicated.
The purpose of this utility model is: provide that a kind of to have manufacturing process simple, rotor inertia descends, and axiality is less demanding, and energy-saving effect is significantly from the speed governing motor special.
The utility model comprise can axially movable stator and main rotor be the rotor and the magnetic shunt mechanism of squirrel-cage.Magnetic shunt mechanism is the outer additional iron core of forming through identical annulus with rotor.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
The utility model embodiment 1 is two stator motors, and it is by main stator 5 movably, secondary stator core 7 of static fully magnetic shunt and cage rotor 6, and inner casing 4, outer cage 3, two end cap 2,8, pull bar 9, drawing dish 10, drawing screw rod 11 are formed.Secondary stator 7 is the diameter circle ring iron core close with rotor 6 external diameters, and it is fixed on the end cap 8 of motor one end, and main stator 5 is fitted in the inner casing 4, is assemblied in jointly in the outer cage 3, it can only be moved axially and can not rotate with guide rail.Rotor 6 is assemblied in motor main stator 5 inner chambers, is supported by bearing (ball) cover 2.8, and is free to rotate.9.10.11 of drawing mechanism or turbine worm can spur inner casing 4 together with main stator 5 axial motions, after main stator 5 parts break away from rotor 6, promptly couple with secondary stator 7, thereby guarantee that the total magnetic resistance of motor magnetic circuit is constant substantially.
Fig. 2 is a double speed rotor speed regulation electric machine structure schematic diagram.It as different from Example 1, secondary stator core 7 develops into the secondary cage rotor 12 of magnetic shunt mechanism and magnetic circuit iron core and fan blade 13.12 and 13 are structure as a whole, and, can freely be rotated around axle in rotating shaft 1 by bearings.After stator 5 parts broke away from rotor 6, promptly with secondary cage rotor 12, magnetic circuit iron core 13 coupled, thereby guaranteed the constant and secondary cage rotor 12 of the total magnetic resistance of motor magnetic circuit, and magnetic circuit iron core and fan blade 13 beginnings are played the ventilation cooling effect with the no-load speed rotation.
The utility model adopts mobile main stator, regulate the coupling ratio of main stator and rotor, and secondary stator plays the flux shunt effect.Thereby, making that the utility model manufacturing process is simple, rotor inertia descends, and axiality is less demanding, can adapt to the fan condition demand again, reaches energy-conservation purpose.
