Abstract
The utility model relates to an alternating current induction motor. The utility model is improved on the existing single-phase alternating current induction motor. The utility model is composed of a machine seat, stators, rotors and rotating shafts. The utility model is characterized in that the machine seat is provided with two stators in parallel. The corresponding rotating shafts are coaxially provided with more than two squirrel-cage rotors; the stators are provided with two groups of main windings. When the utility model is used for the single-phase power supply of 220V, the main windings are in parallel. When the utility model is used for the single-phase power supply of 380V, the main windings are in series. The utility model has the advantages of simple structure, low cost, and one machine with multifunction.
Description
The utility model relates to a kind of induction alternating current (AC) motor.
The utility model is the improvement to existing single phase alternating current (A.C.) induction motor.Existing single phase alternating current (A.C.) induction motor capacity is less, in the use because of the overload rotating speed descend suddenly, make centrifugal switch once more closure cause auxiliary winding to burn; Because of Fraquent start damages centrifugal switch auxiliary winding is burnt.The single phase alternating current (A.C.) induction motor can only be used for 220 volts of power supplys on the other hand, and can not be used for 380 volts of power supplys.
The purpose of this utility model is: a kind of induction alternating current (AC) motor capacious is provided, promptly can be used as single-phase AC motor, can be used as the two-phase alternating current motor again.
The technical solution that realizes above-mentioned purpose is such, and induction alternating current (AC) motor is made up of support, stator, rotor and rotating shaft, it is characterized in that:
A, support are provided with two or more stators arranged side by side, coaxially in rotating shaft accordingly are provided with two or more cage rotors;
B, stator are provided with two groups of main windings, when using as single-phase motor, on terminal block with two groups of main winding parallel connections; When using, on terminal block, two groups of main windings are connected as two phase motor.
The utlity model has the advantage of three aspects:
One, this machine is owing to having adopted plural coaxial rotor, so increased the capacity of motor;
Two, owing to winding and connection to this machine improve, so promptly can be used as single-phase AC motor, uses by this machine, also can be used as the two-phase alternating current motor and use a tractor serves several purposes;
Three, this machine is simple in structure, with low cost, reliable, maintenance is easy to use.
Description of drawings:
Fig. 1 is the utility model structural representation,
Fig. 2 is the connection schematic diagram as the two-phase alternating current motor,
Fig. 3 is the connection schematic diagram as single-phase AC motor.
Below by embodiment, in conjunction with the accompanying drawings the utility model is further described.
As seen from Figure 1, this induction alternating current (AC) motor is made up of support 4, stator, rotor 1 and rotating shaft 5, is installed with two stator cores 2 on the support 4 side by side, and stator winding 3 is housed on it, corresponding in the rotating shaft 5 two coaxial rotors 1 is housed.Come down to two general induction alternating current (AC) motors,, make a capacity bigger motor relatively through above-mentioned rational Design on Plane.
Its connection is promptly specified the connection of sub-winding.When using as the single phase alternating current (A.C.) induction motor, on terminal block that two groups of main winding d1d2, d3d4 are in parallel with auxiliary winding f1f2, f3f4, see Fig. 2 connection; When using as the two-phase induction alternating current (AC) motor, on terminal block, two groups of main winding d1d2, d3d4 are connected with auxiliary winding f1f2, f3f4, see Fig. 3 connection.
