Description
The present invention relates to a kind of improvement of motor, is the asynchronous motor of single-phase pole-changing speed governing, capacitor start.
Along with the continuous development of small processing machinery, monopole asynchronous motor is widely used, and wherein all wants speed change to use more than 80%.The monopole asynchronous motor majority of producing is based on decompression speed at present, and as tapping, modes such as controllable silicon and reactance are carried out speed governing.These methods all realize speed governing to reduce input power, and the power output after the speed change reduces square reducing of multiple by revolution, and the power output grade is very limited, and is difficult to adapt to load request.
The single-phase, polarity-reversing and adjustable speed motor of current production can overcome the shortcoming of above-mentioned mode of speed regulation.But stator winding has three groups, and winding mode is concentric type, and is overlapping each other, brings difficulty to rule in the groove, wasted raw material, and control circuit is complicated.
Purpose of the present invention just provides and a kind ofly can overcome above-mentioned shortcoming, can realize the single-phase asynchronous motor of pole-changing (the 2-4 utmost point) speed governing.
The present invention is achieved in that stator is 24 grooves, is provided with main winding (1) and pays winding (2).Main winding (1) is pressed the chain type series connection winding of 1,3,5,7,9,11 grooves of stator and two groups of symmetries that 13,15,17,19,21,23 grooves are provided with respectively and is formed, two windings have tap A1, A2 and A3, A4 respectively, and tap is connected with external power supply by diverter switch (5).Pay the chain type series connection winding of two groups of symmetries that 6,8,10,12,14,16 grooves that winding (2) press stator respectively and 18,20,22,24,2,4 grooves are provided with and form, connecting with electric capacity (3), centrifugal switch (4) after two windings in series is connected with external power supply.When motor was done the running of two utmost points, diverter switch (5) was beaten to C side, and main winding (1) tap A2 is connected with A3, and main winding (1) is in parallel with the series circuit of paying winding (2), electric capacity (3), centrifugal switch (4), is connected with power supply again.Do four utmost points when running when motor, motor starts by the running of two utmost points earlier, and diverter switch (5) is beaten to D side then, and main winding (1) the tap A2 back that is connected with A4 is connected with power supply, and motor is done the running of four utmost points, and this moment, pair winding (2) was opened a way.
The present invention has broken the traditional speed regulating method of monopole asynchronous motor, promptly main winding, pay a winding number of pole-pairs and change simultaneously, by each phase isopic zone distribute can normal starting mode.Because stator winding of the present invention adopts two groups, and adopts the chain type winding method, not overlapping between two groups, it is convenient to come for so the embedded tape of groove, has saved raw material.And have that control circuit is simple, easy to operate, reliable operation and low cost and other advantages.Stator pays windings in series an electric capacity, has improved detent torque, has reduced starting current.
Fig. 1 is the stator winding expanded view, and (1) is that main winding, (2) are for paying winding.
Fig. 2 is electromotor control circuit figure, and (3) are that electric capacity, (4) are centrifugal switch, and (5) are diverter switch.
Circuit diagram when Fig. 3 is the running of motor two utmost points.
Circuit diagram when Fig. 4 is the running of motor four utmost points.
Below in conjunction with accompanying drawing, describe the concrete structure and the operating state of this invention in detail.
The present invention includes casing, stator, rotor, axle, end cap, fan, stator winding, rotor winding, electric capacity (3), centrifugal switch (4) and diverter switch (5).Inboard 24 notches that evenly distribute of stator, even 30 notches that distribute in the rotor outside.The winding of stator is divided into two groups, be main winding (1) and pair winding (2), the chain type series connection winding that main winding (1) is provided with two groups of symmetries by 1,3,5,7,9,11 grooves and 13,15,17,19,21,23 grooves of stator respectively, two windings have tap A1, A2 and A3, A4 respectively; Tap A2, A3, A4 are connected with the binding post of external diverter switch (5) respectively, and main winding (1) joins with external power supply then.Pay the chain type series connection winding that winding (2) is provided with two groups of symmetries by 6,8,10,12,14,16 grooves and 18,20,22,24,2,4 grooves of stator respectively, draw tap B1 and B2 after two groups of windings in series; Tap B2 connects with external capacitor (3) and centrifugal switch (4), the series circuit of paying winding (2), electric capacity (3) and centrifugal switch (4) composition with join with external power supply after main winding is in parallel.
When the present invention did the two-pole machine running, diverter switch (5) was beaten to C side, and the tap A2 of main winding this moment (1) is connected with A3, and A1 and A4 connect power supply.Pay winding (2) and connect with electric capacity (3) and centrifugal switch (4) as starting winding, again with tap A1 with connect power supply after A4 links to each other.(being lower than rated speed) centrifugal switch (4) action was cut off and is paid winding (a 2) loop when electric motor starting ran to certain rotating speed, and after centrifugal switch (4) was waited to shut down, auto-closing was got ready for starting next time again.At this moment, to make motor as the work winding be two-pole machine running to main winding (1).
When this invents as four utmost point motor rotations, diverter switch (5) is beaten to C side, make motor do the running of two utmost points.And then diverter switch (5) beaten to D side, the tap A2 of main winding this moment (1) is connected with A4, and A1 and A3 connect power supply, make motor as four utmost point motor rotations.Rotating speed of motor is half of two utmost points when running rotating speed during four utmost points.Pay winding (2) because when two-pole machine turned round, centrifugal switch (4) opened circuit it, do not work so pay winding (2) when making four utmost point motor rotations.
