The number of carbon brush is then selected according to size of current, its number by 1,2,3...n do not wait.For ease of fixed installation, the semicircle carbon brush holder for adopting less than 4 carbon brush greater than 180 ° can adopt circular brush holder for the carbon brush greater than 5.For irreversible carbon brush for electric machine, each distributes the carbon brush number of brush holder and number of motor phases to equate (being every carbon brush mutually), for reversible carbon brush for electric machine then the carbon brush number be one times (being two carbon brush of every phase) of number of motor phases.

Irreversible motor phase windings adopts two carbon brush of every phase, i.e. each carbon brush of the head and the tail of phase winding; The carbon brush number that the phase winding of reversible electric machine adopts is four carbon brush, i.e. each two carbon brush of the head and the tail of phase winding; The number of brush-box and carbon brush equate.

Because the carbon brush setting angle position difference (as Fig. 5 f) of reversible electric machine, promptly the angle of flow of clockwise carbon brush is Δ a, is Δ b and close the angle of rupture; The angle of flow that reverses carbon brush is Δ b, and closing the angle of rupture is Δ a; Two pilot angles are just opposite, so reversible electric machine will be with two groups of carbon brush.

For irreversible motor control circuit is greatly simplified, cost reduces.Can save this moment and drive contactor KM1, KM2, and the head end of motor phase windings is connect the carbon brush that V+ distributes carbon brush holder to adapt, the tail end of motor phase windings connects the carbon brush that V-distributes carbon brush holder to adapt, because V+, V-power supply slip ring, distribute slip ring the voltage of confession be idiostatic voltage, so the carbon brush holder that matches with it, brush-box, carbon brush all equate with the rotary slip ring current potential, there is not potential difference, be convenient to make and safeguard, being in operation does not exist phase fault, and this just is superior to the structure of direct current machine armature rectifier, carbon brush holder in the prior art.

Each brush holder needs salient pole two corner Δ a, the Δ b position of 12 carbon brush and its stator to adapt, and constitutes every phase two diagonal angles, forms stator and organizes the corresponding form of head and the tail mutually.A head end carbon brush position Rotate 180 ° mechanical angle is exactly tail end carbon brush position, but the phase winding head end meets positive source V+, the phase winding tail end meets power cathode V-, owing to distribute carbon brush and distribute slip ring to be divided into V+, V-two covers, so only need V+, V-to brush each one of every phase for irreversible motor in the practical application, promptly three-phase is three; Then need each two of V+, the every phases of V-brush holder for reversible motor, promptly three-phase is six.

Only need with 1/4 of its total carbon brush number for small-sized irreversible motor, and only need be with 1/2 of its sum for the compact reversible motor; For middle size motor, electric current then strengthens current value with V+, the two diagonal angle brush-box parallel connections of V-homophase when surpassing the current value of carbon brush.

The number of brush-box is installed in actual applications as required, and also there are two positions the installation site of its homophase brush-box.The V+ of rotation distributes slip ring 20 (Fig. 5 c), it is the full circle rotary slip ring of a convex-concave shape identical with the switch reluctance machine rotor shape that V-distributes slip ring 24 (Fig. 5 d), its lug---be that V+ distributes slip ring power supply sheet 25, it all is domains that V-distributes slip ring power supply sheet 27, its recessed---be that V+ distributes slip ring outage sheet 26, V-distributes slip ring outage sheet 28 to equate also and the magnetic pole of rotor 44 with magnetic pole and recessed number of rotor 44, recessed arc angle equates, is embedded in formation one complete circle in recessed with a shape and structure size and recessed equal concavity sticking patch through insulation mica sheet 29.

All power supply lugs 25,27 and cut off the power supply all obstructedly between recessed 26,28, all distribute and all to insulate obstructedly between this ring outage sheet 26 of slip rings, and all distribute this ring of slip rings to cut off the power supply all to insulate between the sheet 28 obstructed.

Now exemplify the mutually clockwise electrical principle that illustrates of A.When clockwise, clockwise driving contactor KM1 is closed, and stator reverses driving contactor KM2 disconnection.Because the electrical interlocks closure is not, at electric motor starting or V+ in service power supply slip ring 3 electricity is supplied with V+ and distribute slip ring 20, the power supply of can switching on of all power supply lugs 25, and all outages recessed 26 are mutual obstructed and cut off the power supply.
