Abstract
The utility model provides a self-controlled magnetic resistance motor which is a magnetic resistance motor. The utility model solves the problems that the electronic structure of the existing magnetic resistance motor is expensive, the position detecting and the controlling are hardly quite accurate, and the motor torque is small. The self-controlled magnetic resistance motor puts through or cuts off the corresponding electric brush of the stator coil in sequence by the synchronous rotating of a rotor axle center sleeve and a rotor, to achieve the synchronous mechanical on-off. The on-off state of the stator pole coil can be mastered to be more accurate, the complicated and expensive electronic structure is eliminated, and the stator magnetic pole adopts the inside and outside corresponding arrangement, to enhance the portative force to the rotor, and enlarge the motor torque. The utility model is suitable for an electric automobile, an electric bicycle, a helicopter, an electric drill, etc.
Description
The present invention is a kind of self-starting reluctance motor.
Existing reluctance machine all adopts electronic switch to come the control coil electric current, needs complicated and expensive electronic structure such as power inverter, controller, detector.And position probing and control are difficult to accomplish very accurate, influence electric efficiency.
The objective of the invention is to design a kind of complicated electronic structure that need not, cost is low and control is accurate, the mechanical switch formula reluctance motor that rotating torque is big.
Solution of the present invention is that an end of winding coil on each magnetic pole of the stator is linked to each other with the armature spindle core retainer plate by corresponding brush, is linked back in the current supply circuit by the armature spindle core retainer plate again.Fluting embeds unit of plastic shape on the armature spindle core retainer plate, becomes conduction region and insulation layer.Be switched on or switched off corresponding stator coil electric current by the rotor axis cover successively with the synchronous rotation of rotor, realize synchronous mechanical switch.Magnetic pole of the stator adopts inside and outside arrangement relatively simultaneously, and polarity is identical, and the magnetic line of force of forward is suffered oppression to extending laterally, and strengthens the suction to rotor, increases motor torque.
Fig. 1 is this electric machine structure schematic diagram.
Fig. 2 is a cutaway view.3 is stator outer magnetic poles among the figure, the 5th, and stator internal magnetic pole, the 4th, rotor magnetic pole.
Fig. 3, Fig. 4 explain orally the schematic diagram that the relative magnetic line of force side direction of homopolarity strengthens.Fig. 3 represents that the one pole magnetic line of force distributes, and can find out that the density of line of magnetic force of side direction is little, and Fig. 4 is that the relative magnetic line of force of homopolarity distributes, and the magnetic line of force of forward is repelled by the other side and to extending laterally, side direction strengthened to the suction of rotor magnetic pole at this moment.
Embodiments of the invention below are described, for the sake of simplicity, are example with 6/4 utmost point motor.As shown in Figure 1: (for ease of distinguishing, with the shadow representation rotor portion.) coil one end on magnetic pole of the stator B1, the B2 links on the armature spindle core retainer plate 1, the other end links to each other with brush B3, B3 when passing to direct current is because directly contact armature spindle core retainer plate metal surface and conducting, make magnetic pole of the stator B1, B2 produce magnetic attraction rotor magnetic pole H, when magnetic pole H deflects into B1, when B2 overlaps, brush B3 disconnects because of sliding on the unit of plastic 2, brush C3 and F3 are because of sliding into conducting on the metal covering simultaneously, make C1, C2 and F1, F2 attract rotor I and G respectively, so circulation can keep motor to continue to rotate.
Compare with existing electronic switch type reluctance motor, the present invention saved power converter, controller and Complicated and the expensive electronic structure such as detector has reduced cost. Adopt the synchronous of rotor axle core cover and rotor Rotate and to control the switch circuit, it is more accurate that the break-make state recognizing of magnetic pole of the stator coil is got, simultaneously stator magnet The utmost point adopts the structure of repelling mutually up and down, and side direction suction is strengthened, and has increased Motor torque.
Particularly suitable of the present invention is in needs high-torque occasion, as electric automobile, electric bicycle, helicopter, Electric drill etc.
