Abstract
The utility model discloses an auxiliary starter of a single-phase switch reluctance motor, which comprises a shaft and a magnet armature arranged thereon. An electromagnet is arranged coaxially with the magnet armature at the outer part thereof, a pair of opposite projections are arranged on the electromagnet, and a magnet coil is wound between the opposite projections on the electromagnet. In the auxiliary starter provided by the utility model, the magnet armature is arranged on the shaft of the reluctance motor, the electromagnet is arranged in a case, and the magnet coil on the electromagnet is electrified to drive the magnet armature to rotate, so as to drive the rotor to rotate and leave the 'dead zone'; and then the magnet coil is cut off, the single-phase switch reluctance motor operates as usual, and the electric motor generates no incremental loss during the regular service, thereby improving efficiency of the electric motor.
Description
Technical field
The utility model belongs to the reluctance motor technical field, relates to a kind of single-phase switch reluctance motor auxiliary actuator.
Background technology
The single-phase reluctance motor exists torque " dead band ", and when its rotor was in " dead band ", motor can not start.The method of current existing assistant starting has: utilize to be embedded in the epitrochanterian copper billet reluctance torque assistant starting that eddy current produces of inducting; Perhaps use the permanent-magnet steel assistant starting.But these two kinds of assistant starting modes produce supplementary load loss when motor runs well, thereby the efficient of motor is reduced.
Summary of the invention
The purpose of this utility model provides a kind of single-phase switch reluctance motor auxiliary actuator that is installed on the single-phase reluctance motor, has solved the problem that existing single-phase reluctance motor can not start.
The technical scheme that the utility model adopted is, a kind of single-phase switch reluctance motor auxiliary actuator, comprise axle and the armature that on axle, is provided with, armature outside and be coaxially arranged with electromagnet with armature, have on the electromagnet relative protrusion position, between protrusion position relative on the electromagnet, be wound with electromagnet coil.
The utility model single-phase switch reluctance motor auxiliary actuator, axle on the reluctance motor is provided with armature, in casing, be provided with electromagnet,, make to attract armature to rotate earlier with the electromagnet coil power on the electromagnet, thereby drive rotor rotation, break away from " dead band ", again with electromagnet coil outage, single-phase switch reluctance motor operate as normal, motor can not produce supplementary load loss when running well, thereby has improved the efficient of motor.

Wherein, 1. spool, 2. stator, 3. rotor, 4. motor coil, 5. electromagnet, 6. armature, 7. electromagnet coil, 8. rotor position detector, 9. driver.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model single-phase switch reluctance motor auxiliary actuator as shown in Figure 1, comprise axle 1 and the armature 6 that on axle, is provided with, also be included in the outside of armature 6 and with the electromagnet 5 of armature 6 coaxial settings, electromagnet 5 has relative protrusion position, is wound with electromagnet coil 7 between protrusion position relative on the electromagnet 5.
The utility model auxiliary actuator be applied on the single-phase switch reluctance motor structure as shown in Figure 3, the single-phase reluctance motor comprises axle 1, and the rotor 3 that on axle 1, is provided with, in the single-phase reluctance motor field frame, be provided with stator 2, be wound with motor coil 4 on the stator 2, also be provided with rotor position detector 8 on axle 2, the utility model auxiliary actuator is arranged on the axle 1, and electromagnet 5 is fixed in the single-phase reluctance motor field frame.
The control circuit of the utility model single-phase switch reluctance motor auxiliary actuator as shown in Figure 2, K is a three-position switch, when switched reluctance motor put into operation, the contact of K became " b " position by " a " position, make electromagnet coil 7 energisings, thereby armature 6 rotates, and rotor 3 breaks away from " dead band " position, and the K contact is connected " c " position then, the switched reluctance motor startup enters operating condition, simultaneously with electromagnet coil 7 outages.Single-phase switch reluctance motor operate as normal, motor can not produce supplementary load loss when running well, thereby has improved the efficient of motor.
