Abstract
Multi-speed asynchronous AC motor with dual rotors is by differential gear train that its two axis are identical but the synthetic back output that rotatablely moves of the branch rotor that can work respectively, to realize a kind of buncher of speed change.This motor output speed is many, and variable speed operation is easy, is easy to realize fluid drive, has also kept simple, the easily manufactured advantage of Induction Motor Structure simultaneously.
Description
Multi-speed asynchronous AC motor with dual rotors is improved on existing various types of asynchronous machines basis, then by differential gear train with the synthetic back output that independently rotatablely moves of two branch rotors of its inside, thereby realize a kind of novel buncher of speed change, deceleration or speedup.
Two the branch rotor A and B that can work alone are arranged in this motor.The axle of rotor B is a hollow shaft, and the axle sleeve of it and rotor A is fitted together, and constitutes the composite rotors (Fig. 1) of this motor.
The stator of this motor combines (Fig. 2) by the stator A' and the B' of two common single speed asynchronous machines or pole changing asynchronous machine.The winding of motor can be made only formula, single two formulas, single three formulas, multiple patterns such as formula, two three formulas, three or three formulas in pairs as required.(illustrate: only formula is meant that two motors in this motor are single-speed motor.Two three formulas are meant that a motor is a double-speed motor, and another motor is a three-speed motor.Other are roughly the same various) in addition by changing the number of poles of each motor, also capable of being combinedly go out more this motor of polytypic.
This motor internal is being fully independently aspect the electromagnetism by the motor that rotor A stator A' and rotor B stator B' form.They can both press different regular movements respectively.Be connected to a differential gear train at its output.The outwards output again after differential gear train is synthetic that rotatablely moves of rotor A, B makes the output of this double-rotor machine drag load (Fig. 3) with the rotating speed after synthetic.
For can labor the various working conditions of this motor, below temporarily two motors of its inside are all established four utmost point asynchronous machines of making single speed.Forward rotation claims+4, and backward rotation claims-4, halted state is 0.Because two motors in this motor all have above-mentioned three kinds of states, so following nine kinds of states can appear in this double-rotor machine in use.
A B A B A B
+4+4 0+4 -4+4
+4 0 0 0 -4 0
+4-4 0-4 -4-4
In nine kinds of states, have only 00 attitude motors not work in the above.All the other each attitudes, motor all can turn round.That is to say the exportable 8 kinds of different rotating speeds of this motor.
According to the work characteristics of differential gear train, as long as change its input and output side, just can obtain three kinds of different working methods, (Fig. 4) (a) centre wheel 1,3 inputs, pivoted arm H output.(b) centre wheel 1, pivoted arm H input, centre wheel 3 outputs.(c) centre wheel 3, pivoted arm H input, centre wheel 1 output.Therefore the gearratio difference of these three kinds of working methods makes above-mentioned motor obtain 3 groups of totally 24 kinds of rotating speeds by the method that changes input, output.
If A, B are the double-speed motor rotor, suppose that motor all is 8 utmost points, 4 utmost points.This double-rotor machine has 25 kinds of states so, and wherein the operating state of motor has 24 kinds.
A B A B A B A B A B
+8+8 +4+8 0+8 -4+8 -8+8
+8+4 +4+4 0+4 -4+4 -8+4
+8 0 +4?0 0 -4 0 -8 0
+8-4 +4-4 0-4 -4-4 -8-4
+8-8 +4-8 0-8 -4-8 -8-8
Consider three kinds of working methods of differential gear train, this motor can produce 3 groups of totally 72 kinds of rotating speeds altogether.
If A, B are the three-speed motor rotors, then each rotor all has 7 kinds of states.After differential gear train is synthetic, produce 48 kinds of operating states and 00 attitude.If with the working method change of differential gear train, the output speed of this multi-speed asynchronous AC motor with dual rotors just can be selected in 144 kinds of rotating speeds at 3 groups totally.
The step type speed change gear that more than this motor output speed is any gear-shift mechanism and other types is all incomparable.By changing the input of differential gear train, output can make this motor obtain 3 groups of different rotating speeds, and this satisfies the user to manufacturing firm the difference of rotating speed is required to have brought convenience.
The design and the manufacturing process of this motor are simple.The motor part is except that needing to redesign because of the rotating shaft lengthening, and other parts are basic identical with common single speed or pole changing asynchronous machine.Running part can be selected for use simple in structure, compact single in the 2K-H differential gear train of external toothing, and it is installed on this electric motor end cap, to reduce the axial dimension of motor, keep its good looking appearance.
This multi-speed asynchronous AC motor with dual rotors can be realized its speed change with shirtsleeve operation very, is used in various device and mechanically realizes fluid drive easily.In addition because it is simple in structure, compact, the differential gear train running steadily, transmitted power is big, noise is low, therefore the efficient height can be widely used in the various places that need speed change, deceleration or speedup such as lathe, chemical machinery, oil and foodstuffs processing equipment, metallurgical equipment, conveying equipment, to replace or to simplify complicated, the heavy gear drive and the transformation of speed device of other kinds.
