Description
The utility model belongs to electric motors, is specifically related to a kind of pair of stator squirrel-cage motor.
As everyone knows, the squirrel-cage motor that is widely used in worker, agriculture field is a kind of induction motor, and at present, two kinds of methods are mainly adopted in the stepless speed regulation of this kind motor, and the first changes stator power supply frequency, and it two is to adopt slip clutch.Changing the stator power frequency promptly is so-called " frequency control ", although the speed governing effect is fine,, required converter technology complexity costs an arm and a leg, and the maintenance technique level is had relatively high expectations, and one-time investment is bigger, thereby is difficult to promote the use of.Adopt slip clutch promptly so-called " slip motor ", this kind motor efficiency is lower, and efficient is lower when low cruise, and therefore, its application is restricted.
The purpose of this utility model is to overcome interconnected cage motor variable-frequency control technique complexity, maintenance difficult, cost height, the inefficient shortcoming of slip motor, but the low-cost two stator squirrel-cage motors of a kind of power factor height stepless speed regulation are provided.
The purpose of this utility model is achieved through the following technical solutions:
Of the present utility model pair of stator squirrel-cage motor is made of stator, rotor, casing, end cap, bearing, and stator is made of left stator 1 and right stator 2, and the number of magnetic poles of two stators is identical, at a distance of certain distance, is installed in parallel in the casing.On armature spindle 9 with left stator 1, rotor left part iron core 6 is equipped with in right stator 2 corresponding positions, rotor right part iron core 8, on a rotor left side, it between the right part iron core 6 and 8 rigid connector 7 that non-magnet_conductible material is made, pass rotor left part iron core 6, body 7 is fixedly connected, between the groove of the cage bar 13 of rotor right part iron core 8 and rotor core and rigid connector 7 insulating barrier is arranged, make cage bar 13 and rotor left part iron core 6, rigid connector 7, insulation between the rotor right part iron core 8, the stator winding power outlet should guarantee that with the method for attachment of power supply the direction of rotation of the rotating magnetic field that left stator 1 and right stator 2 produce is identical.
The casing of the two stator squirrel-cage motors of the utility model is made of left part casing 15 that left stator 1 is installed and right part casing 3 that right stator 2 is installed, the worm screw 12 that rotatable parts and worm gear 14 be meshed with worm gear 14 is housed on the left part casing 15 is contained on the right part casing 3.
Two stator squirrel-cage motors that this practicality is newly moulded are called fast wide ranges, absence of collector, non-carbonate, do not produce spark, simple in structure, easy to maintenance, sturdy and durable, but the bringing onto load starting, high power motor need not starter, through actual measurement, the motor power (output) factor reaches 0.9 when unloaded, and power factor was higher when load was arranged.
Fig. 1 is the view in transverse section of the utility model motor.
Fig. 2 is the sectional view at A among Fig. 1-A line place.
Fig. 3 is the connection layout of the utility model motor stator winding.
Describe examples of implementation of the present utility model in detail and set forth basic principle below in conjunction with accompanying drawing.
Be wound with left stator winding 20 above the stator 1 of a left side, be contained in the left part casing 15.Be wound with right stator winding 21 above the right stator 2, be contained in the right part casing 3, the magnetic pole of left stator and right stator can be made two utmost points, four utmost points, sextupole, the ends of the earth etc., but the number of magnetic poles of left stator 1 and right stator 2 will equate that the magnetic flux of two stators also will equate.Load onto left casing left part bearing 11, worm gear 14 and left casing right part bearing 10 from right to left successively at the right-hand member of left casing 15, then, insert the left end of right casing 3, load onto left casing bearing (ball) cover 16 afterwards, last, the worm screw 12 of packing into.When by worm screw handle 19 rotary worms 12, worm screw 12 drives worm gear 14, drives left part casing 15 and 1 rotation of left stator.Worm screw 12 also plays the effect of left stator 1 locking position simultaneously.
Load onto rotor left part iron core 6 and rotor right part iron core 8 with left stator 1, right stator 2 corresponding positions on armature spindle 9, core material is the silicon steel sheet with insulating barrier.Be the rigid connector 7 that non-magnet_conductible material is made between rotor left part iron core 6 and rotor right part iron core 8, rigid connector 7 used non-magnet_conductible materials are aluminium.Cage bar 13 is made by red copper, is provided with insulating barrier between the groove of cage bar 13 and rotor core and rigid connector 7, passes rotor left part iron core 6, rigid connector 7, rotor right part iron core 8.Cage bar 13 two ends constitute cage rotor by the short-circuited conducting sleeve short circuit.17 is rotor right part bearing, and 18 is rotor left part bearing, and they can make rotor stability ground rotate.4 is right end cap, and 5 is left end cap.A-X, B-Y, C-Z are the stator winding 20 of left stator among Fig. 3, a-x, b-y, c-z are the stator winding 21 of right stator 2, a, the z end of the stator winding 21 of right stator 2 is connected with the X end of left stator 1 stator winding 20, c, the y end of the stator winding 21 of right stator 2 is connected with the Z end of left stator 1 stator winding 20, x, the b end of the stator winding 21 of right stator 2 is connected with the Y end of left stator 1 stator winding 20, and A, B, C three ends are connected with three-phase alternating-current supply.22 is worm bearing.In order to make the motor heat radiation, can on motor, adorn cooling fan.
When the stator of above-mentioned pair of stator interconnected cage motor is connected three phase mains, left side stator 1, right stator 2 produces a rotating magnetic field separately, the direction of rotation unanimity in magnetic field, the magnetic flux cutting cage bar 13 of two stators, in rotor cage bar 13, produce induced electromotive force, when regulating worm screw 12, drive worm gear 14, driving left stator 1 rotates, the rotating magnetic field magnetic pole S-N axis that allows left stator 1 be produced is consistent with the axis of the rotating magnetic field magnetic pole S-N of right stator 2 generations, at this moment, the magnetic flux that two stators produce two electromotive force of in rotor cage bar 13, inducting respectively, electromotive force equal and opposite in direction, frequency is identical, the direction unanimity, the synthetic electromotive force at rotor cage bar 13 two ends is two induced electromotive force sums, is 2e.
When rotary worm 12, worm gear 14 drives left stator 1 and rotates, when making the rotating magnetic field magnetic pole S-N axis of rotating magnetic field magnetic pole S-N axis that left stator 1 produces and 2 generations of right stator differ 180 ° of electrical degrees, at this moment, the electromotive force equal and opposite in direction that magnetic flux in two rotating magnetic fields is inducted at the two ends of rotor cage bar 13 respectively, frequency is identical, but the direction of electromotive force is opposite, and therefore synthetic electromotive force equals zero.This shows, when regulating worm screw 12, drive worm gear 14 and drive left stator 1 rotation, rotating magnetic field magnetic pole S-N axis that the rotating magnetic field magnetic pole S-N axis that makes its generation and right stator 2 produce is by consistent, change to and differ 180 ° of electrical degrees, the synthetic electromotive force value at rotor cage bar two ends will change to zero by 2e, so regulate the size that the corner of left stator 1 just can change the synthetic electromotive force of two ends of rotor, also just can change the size of rotor current, thereby change the size of motor torque, the torque M=C of motor
mI
2φ cos
2So, regulate the corner of left stator 1, will smoothly change rotor current I
2Size, just can realize stepless speed regulation.
