Embodiment
Fig. 3 has described design principle of the present utility model on the one hand, can be used as again the embodiment that adopts mechanical switch or electromagnetic relay to realize dpdt double-pole double-throw (DPDT), triac device function simultaneously.
In Fig. 3, when double-point double-throw switch S1 and triac device S2 throw into upper switch bit simultaneously, as shown in Figure 4, this circuit is equal to the original motor winding in Fig. 1 to circuit completely, and circuit connecting is at this moment obviously a three phase alternating current motor.When double-point double-throw switch S1 and triac device S2 throw into lower switch bit simultaneously, circuit connects as shown in Figure 5.Comparison diagram 5 can find out with Fig. 2, and two circuit are equivalences completely, and therefore circuit connecting is at this moment three-phase reactor, and each phase coil inductance value is equal to L.
S1 in Fig. 3 and S2 also can be realized by semiconductor electronic switch.Fig. 6 has described a kind of embodiment of the semiconductor single-pole double-throw switch (SPDT) of being realized by two bidirectional triode thyristor T1 and T2.When gate pole G1 passes into trigger current, T1 two-way admittance, on the contrary when alternating current zero crossing, turn-off; Gate pole G2 is like this equally to T2.While passing into trigger current when G1 is different with G2, this circuit can be realized terminal AB conducting or AC conducting, the switching logic of Here it is single-pole double throw.This circuit, through simple copy, can easily be realized the function of dpdt double-pole double-throw (DPDT) and triple-pole double throw.
In it is pointed out that reactor connects, the two-phase in original motor three phase windings has been intercoursed the winding coil of half number of turn, and this is the key technology point in the utility model.The benefit of doing is like this, under reactor connection, makes the stator of motor produce equal and opposite in direction simultaneously, two rotating magnetic fields of opposite direction, and the electromagnetic torque of the two generation is cancelled each other, so machinery-free torque output on motor shaft.The realization of this effect also depends on a condition, and the rotor of three phase alternating current motor must, without saliency, can guarantee that the inductance value of each coil is in full accord when any rotor-position like this.Therefore,, while specifically implementing, the utility model must be limited to three-phase induction (asynchronous) motor, surface-mounted permanent magnet machine etc. without the alternating current machine of saliency.
The inductance parameters L of reactor can consider in the lump when design of electrical motor.The inductance value of design motor winding is the known technology contents of design of electrical motor engineer.
The above is specific embodiment of the utility model and the know-why used, and any equivalent transformation based on technical solutions of the utility model basis, within all belonging to the utility model protection range.
