Description
Technical field
The utility model relates to a kind of compound motor, can be used for all and need belong to the motor technology field with the place of mechanical energy.
Background technology
Motor is widely used in all trades and professions, a motor is made up of output shaft, fan, casing, stator, rotor, bearing, base, terminal box, hood, its operation principle is to convert electric energy to mechanical energy to use for producing, if motor self consumption in operation electric energy is ignored, how many electric energy motor consumes so, also just converts how much mechanical energy to.
Summary of the invention
To be that invention is a kind of convert total mechanical energy to when constant to the purpose of this utility model, only consumes the compound motor of half electric energy.
For realizing above purpose, the technical solution of the utility model provides a kind of compound motor, by left rotor, left bearing, base, left side output shaft, left side fan, casing, left side stator slot, terminal box, hood is formed, its characteristics are, the lengthening base, casing is in an original double-length, be equipped with the wire casing shape support of bearing on left rotor the right, two intermediate bearings, it is sub to turn right, right output shaft, right fan, right bearing, right stator slot, left side output shaft is connected with two intermediate bearings with the other end of right output shaft, two intermediate bearings are fixed by the wire casing shape support of bearing, the wire casing shape support of bearing places casing middle conjuncted with casing, be close to left stator slot and right stator slot on the both sides of the wire casing shape support of bearing, form a stator at conjuncted a few coils that are equipped with of left stator slot and right stator slot outer ring, and closely contact with casing, left side output shaft and right output shaft output equal-wattage, respectively with left bearing, right bearing connects, be connected respectively with right fan with left fan again, left rotor, left bearing, left side output shaft, left side fan, left side stator slot, two intermediate bearings are sub with right-hand rotation respectively, right bearing, right output shaft, right fan, right stator slot is symmetrical, terminal box places the top of casing, is equipped with hood at the two ends of casing.
The utility model is exactly that motor symmetry with two same nominal power is assembled in same casing, the base, two stator slots is merged conjuncted coiling become a stator, becomes compound motor.
After the left motor in the compound motor was connected three-phase alternating current, left rotor rotated under the effect in magnetic field, by left output shaft power output, its electric current I
1Suppose it is that clockwise direction flows, because left and right sides motor has identical rated power, the left and right sides identical symmetry of motor rotor specification is assembled in same casing and the stator, in right-hand rotation of right motor, cause mutual inductance phenomenon, thereby produce induced electromotive force and induced current, and then form induction reactance.According to electrical principles, in the pure inductance circuit, induction reactance is consumed power not, also we can say, under same stator field effect, right motor be keep left the rotating magnetic field that the motor closed circuit produces effect and rotate.Consequent induced current I
2With I
1Flow direction is identical also to flow for clockwise direction.
In addition, also can see according to the derivation of equation:
If the active power P=IVCOS Φ of compound motor
In the formula: P is an active power, and I is an electric current, and V is a voltage, and COS Φ is a power factor.
Left side motor active power P
1=I
1V
1COS Φ
Right motor active power P
2=I
2V
2COS Φ
P=P is then arranged
1+ P
2=V
1I
1COS Φ+V
2I
2COS Φ
Owing to cause by mutual inductance phenomenon, so I
1=I
2, V
1=V
2,
P=2I then
1V
1COS Φ
So P/P
1=2I
1V
1COS Φ/I
1V
1COS Φ=2
This is explanation just, and compound motor uses the electric energy of a motor, just can obtain double power output, in other words, when electric energy converts mechanical energy to, make total mechanical energy constant, only wants the electric energy of half just can achieve the goal.
The utility model has the advantages that to convert total mechanical energy to when constant, only consume half electric energy.
