Abstract
The utility model relates to a double winding series energy saving motor which is composed of a stator, a rotor and a motor base. The utility model is characterized in that the stator of the motor is respectively provided with two windings, wherein, ends of large winding are connected, namely, connected into a Y shape; the end of small winding is connected to the head end of the large winding, namely, connection in series. The turn ratio of the small windings and the large windings is within the range of 1/5 to 1/2. After the connection in series of the two windings, the head ends (three phases) of the small winding is led out and connected to a set of terminals of a terminal box. A tap is led out between the two windings, and is connected to a set of terminals of the terminal box which is provided with two sets of wiring terminals; each set of the wiring terminals is provided with wiring ends. Two sets of wiring terminals are respectively connected with two AC contactors which are controlled to be closed in different time by using of interlock circuits. The utility model has the advantages that when the motor runs, wiring modes can be selected according to loading conditions; when the load is light, the series wiring mode is selected, the exciting current is small, the power factor is high, the consumption of the windings and electric network can be reduced, and the purpose of energy saving at the time of light load can be achieved.
Description
The utility model belongs to machine field, is used for the drive motors of beam-pumping unit.
Beam-pumping unit is main mechanical oil recovery equip ment, but beam-pumping unit exists some unfavorable factors.Mainly be that starting torque is big, counterbalance effect is poor.During operation, the average load rate is low, and generally about 0.3, the motor long-play is in light condition, and power factor is very low, and operational efficiency is also lower, causes the increase of energy consumption, therefore, according to the characteristics of beam-pumping unit, designs a kind of New-type electric machine and is very important.
The purpose of this utility model is that a kind of double winding series connection energy-saving electric machine will be provided, as the drive motors of beam-pumping unit.
The purpose of this utility model is achieved in that by stator, rotor and support forms motor.It is characterized in that two windings are arranged on the stator of motor, a big winding and a little winding, the end of big winding is connected together, and promptly is connected into the Y type.The end of little winding is connected on the head end of big winding, i.e. series connection.The ratio of the number of turn of little winding and big winding is 1: 5-1: in 2 the scope.After two windings in series, the head end of little winding (three-phase) is drawn on one group of terminal receiving terminal box, and tap is drawn in the centre of two windings, and tap is received on one group of terminal of terminal box.Two set of connections terminals can connect two A.C. contactors respectively, through A.C. contactor, insert three phase mains again.Adopt interlock circuit to control and realize that two A.C. contactors are not closed simultaneously.

Accompanying drawing 1 is the double winding series electric motor stator winding elementary diagram that proposes according to the utility model.
Describe concrete structure of the present utility model and running in detail below in conjunction with accompanying drawing.
The rotor of double winding series connection energy-saving electric machine is identical with common y series motor with casing, and different is the design of stator winding.Two windings are arranged on the stator, a big winding and a little winding, the end of big winding is connected together, and promptly is connected into the Y type.The end of little winding is connected on the head end of big winding, i.e. series connection.The ratio of the number of turn of little winding and big winding is 1: 5-1: in 2 the scope, after two windings in series, the head end of little winding (three-phase) is drawn on one group of terminal receiving terminal box, and tap is drawn in the centre of two windings, and tap is received on one group of terminal of terminal box.Two set of connections terminals can connect two A.C. contactors respectively, through A.C. contactor, insert three phase mains again.Adopt interlock circuit to control and realize that two A.C. contactors are not closed simultaneously.When starting, binding post A

2The series connection winding parameter comes down to fall Capacity design by the power designs of the underloading scope of often working.Because slot space is limited, therefore, power factor and efficient when improving underloading, the performance index of full load can have decline slightly, but reach or can accomplish near GB.
The utility model has the advantages that two windings in series are arranged together on the motor stator, according to wye connection, Middle tap picks out as one group of lead-in wire. During the motor operation, can select the wiring mode according to loading condition. When load is light, select the series wiring mode, the excitation electric current is little, power factor height, winding loss and electrical network Loss all reduces, thus energy-conservation purpose when reaching underloading. When load is increased to a certain degree, in the selection Between tap wiring mode, at this moment the turns-in-series of winding is few, the excitation electric current increases, the power output of motor increases Add, at this moment the load factor of motor is also higher, so efficient and power factor are higher, are very suitable for like this taking out This class load of oil machine. Simultaneously, binding post only has two groups (6 wiring ends), and is bigger to bringing in the control Convenient.
