The specific settings are as follows:
referring to fig. 1 and 5, the motor-driven commutation control architecture 2 includes a PCB circuit board 21, and a three-phase power input terminal 22, a safety module 23, a power switch module 24, a commutation module 25 and a motor terminal 26, which are respectively integrated on the PCB circuit board 21 and electrically connected in sequence.
The three-phase power supply access end 22 is connected with the control output end of the control panel 1 through a circuit, and the three-phase power supply access end 22 comprises a power supply access end L1, a power supply access end L2 and a power supply access end L3; the motor terminal 26 is electrically connected with the motor 4 through a connection control output line, and the motor terminal 26 comprises a motor terminal A, a motor terminal B and a motor terminal C.
Referring to fig. 1 to 2, the safety module 23 includes two safety tube sets, the power input end L1 is electrically connected to an electrical input end of one of the safety tube sets, and the power input end L2 is electrically connected to an electrical input end of the other safety tube set.
Preferably, each fuse group comprises at least two fuse tubes which are arranged in parallel, and when the motor 4 is started, the starting current of the motor 4 is generally about 7 times of the rated current, so that the possibility that the fuse tubes are burnt out can be effectively reduced through larger starting instantaneous current, and the overall operation safety and the functional stability of the system are further improved.
More preferably, PCB circuit bottom plate 21 electricity is connected and is equipped with first PCB circuit riser plug-in area 211, just PCB circuit bottom plate 21 passes through the perpendicular rigid coupling of first PCB circuit riser plug-in area 211 has first PCB circuit riser 213, insurance module 23 electricity is connected and is located first PCB circuit riser 213 is used for adopting vertical picture peg technology effectively to reduce the area occupied to PCB circuit bottom plate 21.
The power switch module 24 includes three normally open relays, which are a first normally open relay, a second normally open relay and a third normally open relay, respectively; the electric input end of the first normally-open relay and the electric input end of the second normally-open relay are respectively electrically connected with the electric output ends of the two fuse tube groups in a one-to-one correspondence manner, and the electric input end of the third normally-open relay is electrically connected with the power supply access end L3, so that when the motor 4 is switched in a forward rotation and a reverse rotation manner, the power supply is firstly cut off, the motor stops rotating, and then the forward rotation and the reverse rotation are switched. Because the motor suddenly jumps to the reverse rotation when rotating forwards or suddenly jumps to the forward rotation when rotating backwards, the two states can generate instantaneous heavy current, so that a fuse tube of the safety module 23 is burnt out and the internal structure of the motor 4 is permanently damaged, and the safety module 23 and the motor 4 are protected by the power-off action of the normally-open relay.
Referring to fig. 1 and 3, the reversing module 25 includes four reversing relays respectively having a normally open contact and a normally closed contact, and the four reversing relays are respectively a first reversing relay, a second reversing relay, a third reversing relay and a fourth reversing relay; the electric output end of the first normally-open relay is connected with the first reversing relay through a circuit, the electric output end of the second normally-open relay is connected with the second reversing relay through a circuit, the normally-open contact of the first reversing relay is connected with the normally-open contact of the third reversing relay through a circuit, the normally-open contact of the second reversing relay is connected with the normally-open contact of the fourth reversing relay through a circuit, the normally-closed contact of the first reversing relay is connected with the normally-closed contact of the fourth reversing relay through a circuit, the normally-closed contact of the second reversing relay is connected with the normally-closed contact of the third reversing relay through a circuit, the motor terminal A is connected with the third reversing relay through a circuit, the motor terminal B is connected with the fourth reversing relay through a circuit, and the motor terminal C is connected with the electric output end of the third normally-open relay through a circuit.
When the four reversing relays work simultaneously, normally open contacts of the four reversing relays are all closed, at the moment, the first reversing relay is connected to the third reversing relay through a circuit, and the second reversing relay is connected to the fourth reversing relay through a circuit; when the four reversing relays do not work at the same time, the contacts of the four reversing relays stay at the normally closed contacts, at the moment, the first reversing relay is connected to the fourth reversing relay through a circuit, and the second reversing relay is connected to the third reversing relay through a circuit, so that the reversing controllability is realized; meanwhile, because the motor 4 can shake when working, and the motor 4 itself can shake, and in the process of shaking, the commutation relay can produce the misoperation, for example, under the condition that a certain commutation relay contact is not controlled, the normally closed contact can be operated by mistake to the normally open contact, which is unavoidable, because the contact of the normally closed contact is supported by the elastic force of the elastic sheet in the relay, the force is far less than that of the normally open end by the electromagnetic attraction, so that the misoperation which can be caused by the shake of the normally closed contact can exist, through the arrangement of the four commutation relays, no matter any one or more of the normally closed contacts are operated by mistake, the common end of the commutation relay is connected to the normally closed contact or the normally open contact, and the third commutation relay and the fourth commutation relay can not be simultaneously electrically connected with the first commutation relay and the second commutation relay, so that the transient short circuit of the first commutation relay and the second commutation relay can be skillfully avoided when the commutation relay is operated, and the operation stability of the system is improved. And two switching-over relays are connected in series, the creepage distance between the switching-over relays is increased, and the creepage distance can reach twice of the contact distance.
The starting process of the motor 4 under the matching of the reversing module 25 and the power switch module 24 is as follows: the reversing module 25 is firstly switched to a forward rotation state or a reverse rotation state, three normally open relays of the power switch module 24 are closed after delaying for a period of time, and 0.5 second can be selected, and then the motor 4 is powered on and started; the process of stopping the motor 4 is just opposite, the three normally open relays of the power switch module 24 are powered off first, so that the motor 4 is powered off, the motor stops rotating after being waited, and then the reversing module 25 is operated to be switched to a reverse rotation state or a forward rotation state. That is to say, when the commutation module 25 is in operation, the motor 4 and the commutation module are always in a power-off state, so as to prevent the motor current from corroding the arc of the commutation module or preventing the internal structure of the motor 4 from being damaged.
Preferably, please refer to fig. 4, PCB circuit bottom plate 21 is still connected electrically and is equipped with second PCB circuit riser plug-in area 212, just PCB circuit bottom plate 21 passes through the perpendicular rigid coupling of second PCB circuit riser plug-in area 212 has second PCB circuit riser 214, two of them the switching-over relay electricity is connected and is located second PCB circuit riser 214, two of others the switching-over relay electricity is connected and is located PCB circuit bottom plate 21, and four the orientation of switching-over relay is 90 degrees angle setting between two liang for can avoid the vibrations of same direction to lead to four switching-over relays to produce the same malfunction simultaneously through above-mentioned three-dimensional overall arrangement and angle setting furthest, and then jump suddenly between jump of motor under the state of just reversing, further promoted operating stability.
