By Fig. 1 to Fig. 4 as seen, the present invention 1 has a contact electric power controller, comprises that parts such as stator 1, rotor 2, pedestal 3, brush 4, commutator segment 5, slip ring 6, end cap 7 and other bearings, spring form.Stator, rotor adopt the insulating material manufacturing, pedestal, end cap adopt insulating material or metal material manufacturing all can, slip ring, commutator segment and outer lead are the copper conductive material manufacturing.Slip ring, commutator segment are embedded on the interior circle of stator, and brush is installed in the rotor brush groove, and the bullet Huang compresses, brush cross-over connection slip ring and commutator segment, and rotor is by department's clothes motor (interconnected cage motor of DC motor or contactless control) driving.See Fig. 5 Fig. 6, the electric power controller commutator segment is exported 12 lines and is connect 12 incoming lines of motor, and motor is 12 groove the two poles of the earth machines, and brush rotates a circle, and is exactly power supply is finished a week on stator winding switching.If commutator segment becomes 24, commutator segment 1 to 12 wiring is constant, commutator segment 13 to 24 docks with commutator segment 1 to 12 respectively, two brushes of power supply become be mutually 90 the degree, then brush rotates a circle, power supply is finished the switching in two weeks on stator winding, if 36 commutator segments in like manner, with the quadrat method wiring, then brush rotates a circle, and power supply is finished the switching in three weeks on stator winding, if number of segment is m times (m is enforceable integer) of motor windings number, then brush rotates a circle, and power supply is finished the switching in m week on stator winding.When power supply was direct current, the rotating speed of the rotating magnetic field that stator winding produces equaled the rotating speed that power supply switches on stator winding, and the m that equals to have contact electric power controller rotor speed doubly.When power supply when being single-phase, the stator field rotating speed increases a synchronous speed, and the adjusting rotating speed stack with power supply switches winding if two rotating speed direction of rotation are identical, is supersynchronous speed governing, if two rotating speed direction of rotation are opposite, is low synchronousing speed-regulating.A single-phase cover winding motor starts and must start with controller, if supersynchronous speed governing continues raising speed and reaches desired value, if low synchronousing speed-regulating, behind the motor starting, the controller rotor slows down to reverse and reaches desired value.
Replace the contactor control device with thyristor, be contactless electric power controller, a thyristor replaces a commutator segment, good output waveform, and the cost height, switching one week of winding needs 6 at least, and two of conductings are circled for three times.Fig. 8 is 6 unidirectional thyristor control simplex lap winding interconnected cage motors, and its conducting is 1,4 → 3,6 → 5,2 in proper order, otherwise also can, switching once is 120 degree, and three times 360 degree are only controlled the thyristor conducting, automatically shut down by commutation winding back-emf, 1,4 place's conducting states for example, electric current flow to 4 from 1, when 3,6 conductings, electric current flows to 6 from 3,1 to 3 winding commutation produces back-emf and makes 1 to turn-off, and 4 to 6 winding commutations make 4 to turn-off.Control the turn-on frequency of these 6 thyristors, just regulated the rotating speed of motor.Fig. 7 power supply is single-phase, and with 6 bidirectional thyristor control simplex lap winding interconnected cage motors, its control principle is identical with Fig. 8.Voltage drop is on winding, and thyristor does not bear the reverse voltage that power supply adds.
