Please refer to fig. 1 and fig. 2.
The embodiment provides a relay control multi-motor forward and reverse rotation circuit which comprises three relay groups in figure 1 and four starting relays in figure 2 or figure 3.
The three relay groups in fig. 1 respectively comprise three groups of relays KA1 and KA2, relays KA3 and KA4, and relays KA5 and KA 6.
Relays KA1 and KA2 are respectively used for controlling the forward rotation and the reverse rotation of the motor M1;
relays KA3 and KA4 are respectively used for controlling the forward rotation and the reverse rotation of the motor M2;
relays KA5 and KA6 are used to control the forward rotation and reverse rotation of motor M3, respectively.
Further, electrical symbols "+" and "-" in fig. 1 respectively represent the positive and negative poles of the power supply, and are used for respectively supplying power to the relays KA1 to KA6 and supplying power to the motors M1 to M3.
In the relay KA1 and the relay KA2, the relay KA1 comprises at least two normally open contacts which are used for respectively introducing the positive electrode and the negative electrode of a power supply, so that the relay KA1 can supply power to the motor M1 when attracting. The relay KA2 comprises at least two normally open contacts for respectively leading in the positive and negative electrodes of a power supply, so that the relay KA2 is attracted to supply power to the motor M1. When the relay KA1 is attracted and the relay KA2 is attracted, the polarities of power supplies connected to the motor are opposite in the two states, so that the relay KA1 is ensured to control the motor M1 to rotate forwards, and the relay KA2 is ensured to control the motor M1 to rotate backwards.
In the relay KA3 and the relay KA4, the relay KA3 comprises at least two normally open contacts for respectively introducing the positive and negative electrodes of a power supply, so that the relay KA3 supplies power to the motor M2 during suction. The relay KA4 comprises at least two normally open contacts for respectively leading in the positive and negative electrodes of a power supply, so that the relay KA4 is attracted to supply power to the motor M2. When the relay KA3 is attracted and the relay KA4 is attracted, the polarities of power supplies connected to the motor are opposite in the two states, so that the relay KA3 is ensured to control the motor M2 to rotate forwards, and the relay KA4 is ensured to control the motor M2 to rotate backwards.
In the relay KA5 and the relay KA6, the relay KA5 comprises at least two normally open contacts for respectively introducing the positive and negative electrodes of a power supply, so that the relay KA5 supplies power to the motor M3 during suction. The relay KA6 comprises at least two normally open contacts for respectively leading in the positive and negative electrodes of a power supply, so that the relay KA6 is attracted to supply power to the motor M3. When the relay KA5 is attracted and the relay KA6 is attracted, the polarities of power supplies connected to the motor are opposite in the two states, so that the relay KA5 is ensured to control the motor M3 to rotate forwards, and the relay KA6 is ensured to control the motor M3 to rotate backwards.
Further, the relay KA1 and the relay KA2 are electrically interlocked, and the auxiliary contacts KA1 and KA2 are arranged.
Further, the relay KA3 and the relay KA4 are electrically interlocked, and the auxiliary contacts KA3 and KA4 are arranged.
Further, the relay KA5 and the relay KA6 are electrically interlocked, and the auxiliary contacts KA5 and KA6 are arranged.
The relays KA1 to KA6 are respectively provided with starting switches K1 to K6, and when the starting switches K1 to K6 are closed, coils of the relays KA1 to KA6 are attracted.
Furthermore, only one starting relay works at the same time. The starting relay is provided with a plurality of auxiliary contacts for controlling the three relay groups to work or stop working.
As shown in FIG. 2, the four start relays are relays KB 1-KB 4. The relays KB 1-KB 4 are respectively provided with three normally open contacts. Specifically, as shown in fig. 2, three normally open contacts of the relay KB1 are connected to the start switches K1, K4 and K6, respectively. The three normally open contacts of the relay KB2 are connected to the starting switches K2, K3 and K6, respectively. The three normally open contacts of the relay KB3 are connected to the starting switches K2, K4 and K5, respectively. The three normally open contacts of the relay KB4 are connected to the starting switches K2, K4 and K6, respectively.
Therefore, the starting relay can realize the switching of the forward and reverse rotation states of the motors according to the difference of the connected starting switches.
Thus, when the starter relay is connected as shown in fig. 2:
the switch A is closed, the relay KB1 is closed, the starting switches K1, K4 and K6 are closed, at the moment, the motor M1 rotates forwards, and the motor M2 and the motor M3 rotate backwards;
closing the switch B, closing the relay KB2, closing the starting switches K2, K3 and K6, wherein the motor M2 rotates forwards, and the motor M1 and the motor M3 rotate backwards;
closing a switch C, closing a relay KB3, closing starting switches K2, K4 and K5, wherein the motor M3 rotates forwards, and the motor M1 and the motor M2 rotate backwards;
and (3) closing the switch D, closing the relay KB4, closing starting switches K2, K4 and K6, and fully reversing the motors M1, M2 and M3 at the moment.
When the starter relay is connected as shown in fig. 3:
the switch A is closed, the relay KB1 is closed, the starting switches K1, K3 and K6 are closed, at the moment, the motors M1 and M2 rotate forwards, and the motors M3 rotate backwards;
closing the switch B, closing the relay KB2, closing the starting switches K2, K3 and K5, wherein the motors M2 and M3 rotate forwards at the moment, and the motors M1 rotate backwards;
closing a switch C, closing a relay KB3, closing starting switches K1, K4 and K5, wherein the motors M1 and M3 rotate forwards at the moment, and the motors M2 rotate backwards;
and (3) closing the switch D, closing the relay KB4, closing starting switches K2, K4 and K6, and fully reversing the motors M1, M2 and M3 at the moment.
By analogy, different combinations of forward and reverse rotation states of the three motors can be realized by increasing the number of the starting relays.
Further, when more motors need to be controlled, the forward and reverse rotation state control of more motors can be realized by increasing the number of the relay groups and the starting relays, and different combinations of the forward and reverse rotation states of more motors can be realized.
In conclusion, the relay provided by the embodiment controls the multi-motor forward and reverse rotation circuit, the logic is visual, and diversified logic control can be realized through transverse and longitudinal orderly connection through the change of the relay 0/1; compared with software control, the method has the advantages of low threshold, low cost and high reliability; the circuit is convenient to establish and modify, software does not need to be rewritten, and logic change can be realized by changing the wiring position.
