Embodiment:
As shown in Figure 1, adopt the frequency conversion actuator of switched Reluctance Motor Control, comprising: moment stroke limiting stop 1 also comprises switched reluctance machines 2, and the axle of switched reluctance machines 2 is connected with the gear of moment stroke limiting stop 1.
As shown in Figure 2, at first on front end housing 203, be bumped into fore bearing 202, refilling back-up ring 201 blocks fore bearing 202, screw rod is twisted 212, double-screw bolt 204 is screwed to respectively on front end housing 203 inner faces, the rotor position detection plate 205 that two optoelectronic induction devices are housed installed on the double-screw bolt 204 fix with nut, one end and front end housing 203 snappings of the motor casing that stator 207 is fixed by screw rod 212 itself and stator 207, the rotor 208 that is fixed with shadow shield 206 is in advance inserted in the stator 207, one end axle of its rotor 208 is bumped in the fore bearing 202, rear bearing 210 is installed on the other end axle of rotor 208, the other end snapping of the motor casing that rear end cap 209 is fixed by four screw rods 212 and stator 207, with nut 213 by packing ring respectively with four screw rods 212 be spirally connected fixing, at last with plug screw 211 spiral-locks on rear end cap 209.
Operation principle:
The stator of switched reluctance machines and rotor core are repeatedly to be adorned by silicon steel sheet to form, and are evenly distributed with tooth and groove (tooth is called " salient pole " again) at stator core inner periphery and rotor core excircle, constitute the biconvex electrode structure.Concentrated winding as the direct current machine main pole coil is installed on each salient pole of stator core; There is not winding on the rotor with salient pole, absence of commutator and brush yet.Windings in series on the stator circumference on relative two salient poles becomes a phase winding.When certain phase winding energising, will produce a reluctance torque, try hard to make this phase winding axis of contiguous rotor with salient pole and stator to coincide, if order is given the energising of stator phase winding, rotor is rotated continuously.Change the power-up sequence of winding, the rotation direction of rotor also changes.Adopt optoelectronic induction to come the detection rotor position, come drive motors thereby provide trigger impulse.
Two kinds of control modes of switched reluctance machines: low speed copped wave control and the control of high speed pulse.
