Abstract
A three-phase power-variable asynchronous motor. The stator winding of the single-phase winding machine is made into a three-phase single-layer concentric winding, each phase of winding adopts a double-wire parallel winding, and one single-wire winding is connected with a normally open contact of a contactor in series and then connected with the other single-wire winding in parallel to form the single-phase winding. When the motor works, the power of the motor can be changed by only operating the control system of the contactor. The motor can change the power of the motor according to the load, thereby achieving the purpose of saving electric energy. Meanwhile, the device also has the advantages of simple structure, convenient use, high efficiency, long service life and the like.
Description
The utility model relates to a kind of transformation of motor, specifically is the asynchronous motor of the following three phase transformation power of a kind of 10KW of being used for.
At present, the coiling of the stator winding of threephase asynchronous all is according to the power coiling of motor, and the problem that this motor exists is a transform power as required, so often under the operational environment of induction-motor load variation, cause low load with strong power, the phenomenon of the useless electric energy of wave.
The purpose of this utility model is exactly can not transform power in order to overcome existing threephase asynchronous, the deficiency of the useless electric energy of wave, the three-phase power-changeable asynchronous motor that a kind of easy to use, power variable, saves energy is provided and increases the service life.
In order to achieve the above object, turn to three-phase individual layer concentric type winding in the stator winding of asynchronous motor, every phase winding all adopts two-wire and around winding, compose in parallel single-phase winding with another single line winding after wherein a single line winding is connected with the normally opened contact of contactor, three single-phase windings connect into corner connection.
Contactor of the present utility model with start knob, stop knob, protector is connected and power supply joins, starting switch is in parallel with the normally opened contact of contactor.
The utility model is owing to adopted the said structure form, and behind motor start-up, the single line winding in its every phase two-wire winding is serially connected with the normally opened contact of contactor and only makes another single line winding work, and motor is in work under the low power state.When pressing the startup knob, contactor work, its normally opened contact closure, and the two-wire winding is worked simultaneously, motor is in work under the high power state.When pressing when stopping knob, the contactor outage, its normally opened contact opens, and works and another single line winding work in the two-wire winding, motor are in again low power state under.
The convertible power of the utility model tool, easy to use, efficient height, characteristics such as saves energy and motor long service life.It is suitable for the operational environment of the frequent conversion of induction-motor load.
Fig. 1 is a structural representation of the present utility model, and sequence number is single line winding (1), single line winding (2), contactor (3), start button (4) and stop knob (5).
Fig. 2 be single line winding (1) and single line winding (2) and around three-phase individual layer concentric type developed winding diagram.
As shown in Figure 1, with power is that the utility model that 4KW and 5.5KW change mutually is an example: its stator slot is 24 grooves, with the winding wire diameter is that 0.96mm becomes individual layer concentric type two utmost point three-phase stator winding with 0.90mm and in stator slot, and every groove number of turn is 53 circles, and its expanded view is seen Fig. 2.
Winding wire diameter is that the winding of 0.96mm coiling is single line winding (1), and winding wire diameter is that the winding of 0.90mm coiling is single line winding (2).The normally opened contact 2C of single line winding (2) series contactor of every phase composes in parallel the three-phase double winding with every single-phase winding (1) mutually then.The three-phase double winding becomes corner connection in succession, is connected with three phase mains again.
Contactor ZC(3) with start button (4), stop knob (5), protector RD connects, and is connected start button (4) and contactor ZC(3 again with power supply) normally opened contact ZC in parallel.
When the utility model is under low-power (4KW) state work and need be converted under high power (5.5KW) state work, press start button (4), contactor ZC(3) work, make normally opened contact ZC closure, the single line winding (1) of every phase and single line winding (2) parallel operation, and make motor be in work under the high power state.When unclamping start button (4), contactor ZC(3) normally opened contact ZC self-insurance.
When the utility model is under high power (5.5KW) state work and need be converted under low-power (4KW) state work, press and stop knob (5), contactor ZC(3) outage, make normally opened contact ZC separately, the single line winding (1) of every phase is worked, and makes motor be in work under the low power state.
Claims (2)
1, a kind of three-phase power-changeable asynchronous motor, form by casing, end cap, fan, stator winding, rotor etc., it is characterized in that stator winding turns to three-phase individual layer concentric type winding, every phase winding all adopts two-wire and around winding, composes in parallel single-phase winding with another single line winding after wherein a single line winding is connected with the normally opened contact of contactor.
