Abstract
The utility model belongs to the technical field of AC squirrel cage asynchronous motor, which is formed by connecting an electromagnetic speed increasing mechanism with a motor in parallel. The utility model discloses simple structure uses easy maintenance, has solved asynchronous motor more economically and has obtained the difficult problem of high rotational speed, and it can realize required 3000r/min-6000 r/min's high rotational speed to can realize the multistage step speed change below 6000 r/min.
Description
The utility model belongs to mouse cage AC asynchronous motor technical field.
Existing mouse cage AC asynchronous motor, because be subjected to the restriction of supply frequency, when it is powered at supply frequency 50Hz, maximum speed (synchronous speed) is no more than 3000r/min, improve rotating speed, will improve frequency of supply, two kinds of methods are arranged at present, the one, adopt the frequency conversion unit, promptly adopt alternating current motor to drag induction generator, to improve frequency of supply; Another kind method is exactly to utilize the frequency-variable electronic device of variable frequency, to improve frequency of supply, realizes improving motor speed.Though adopt the motor of frequency conversion unit power supply comparatively simple, the power-supply device complexity, huge, also be unfavorable for disperseing to use and control; Though adopt the speed governing of frequency-variable electronic device Frequency Adjustable, maximum current is subjected to element limits, maintenance is difficulty, and price is more expensive, and harmonic wave is bigger, and is totally unfavorable to motor performance.
The purpose of this utility model just provides a kind of high speed AC asynchronous motor that need not use variable frequency power supply.It only on the basis of common mouse cage asynchronous motor, changes its internal structure, thereby realizes the high rotating speed of required 3000r/min-6000r/min, and can realize the many grades of step speed changes that 6000r/min is following.
Main points of the present utility model are: the electromagnetism speed increasing mechanism of being made up of stator core, coil, cage rotor etc. and motor are mutually and connect.The electromagnetism speed increasing mechanism is introduced alternating current, drag the iron core of electric motor and coil (or cage rotor) rotation that combine as a whole with it, and motor is also introduced same alternating current, the rotating magnetic field that produces, again with respect to rotation itself, two rotations are superimposed, just can export the rotating speed of 3000-6000r/min on the main shaft of motor.Electromagnetism speed increasing mechanism and motor cooperatively interact, and also can obtain near 1500,2000,2250,3000,3750,4000, the rotating speed of 4500r/min.
The utility model is simple in structure, uses easy to maintenancely, has solved asynchronous motor more economically and has obtained a high-revolving difficult problem, and can realize multistep speed regulation.Under the prerequisite that keeps the asynchronous motor series of advantages, every electricity function indexs such as its efficient, power factor, starting performance, overload capacity are all suitable with the serial motors that the unification of the motherland of same specification designs.
Description of drawings:
Fig. 1 is the structure intention of the utility model concatenation type embodiment
Fig. 2 is the structural representation of the utility model eclipsed form embodiment.
Describe structure of the present utility model in detail below in conjunction with embodiment.
The electromagnetism speed increasing mechanism is made of fixed core and coil 4, cage rotor 5 etc., electromagnetism speed increasing mechanism and motor are in parallel, iron core and coil 8(or and cage rotor 9, the magnetic shield 12 of motor of electromagnetism speed increasing mechanism by inner end cap and bearing 7,10 and motor) be connected as a single entity.The electromagnetism speed increasing mechanism closes 6 by the wiring on the support and directly introduces AC power, and motor then closes 6 by carbon brush and slip ring 2 by wiring and introduces same AC power.In the electromagnetism speed increasing mechanism stator winding because be connected with AC power, just cause a rotating magnetic field, the interaction of the cage rotor 5 of this rotating magnetic field and electromagnetism speed increasing mechanism produces a torque, the cage rotor 9 of the iron core of drive motor and coil 8(or motor) rotation.Meanwhile, in the motor winding, flow through alternating current equally, generation has rotating magnetic field, this also will produce an electromagnetic torque, make the iron core and the coil 8 of motor cage rotor 9(or motor) rotation, the rotation that speed increasing mechanism and motor produce is superimposed, just can on motor main shaft, export the required 3000r/min that is higher than, be lower than the rotating speed of 6000r/min.
