Principle of work of the present utility model is as follows: during wiring, first sees the rated voltage on motor nameplate, when rated voltage is 380v, adopts " triangular form " connection; When rated voltage is 220v, adopt " star-like " connection.After measured motor carefully connects the wire, open air switch 1 and two gear switch SBP, when motor is normal, the 220v alternating current at 24v direct supply 2 input end access T-phase and zero line two ends, exports the direct current of 24v in 24v direct supply 2 after transformation, rectification, filtering, voltage stabilizing from output terminal.Press after rotating forward switch S BT1, on the first D.C. contactor KM1, coil two ends pass into the direct current of 24v, and on main circuit, the main normally closed interlock of the first D.C. contactor KM1 closes, and electric current flows into motor through terminal through position 7, and motor rotates forward, meanwhile, secondary normally opened contact on first D.C. contactor KM1 also closes, on secondary normally opened contact two ends, series connection one rotating forward pilot lamp 3 is in parallel with rotating forward switch S BT1 together, because rotating forward switch S BT1 is point contact type, its self-locking is realized by the secondary normally opened contact on the first D.C. contactor KM1, even if after rotating forward switch S BT1 reset, motor still rotates forward, rotate forward on switch S BT1 and comprise one group of normally opened contact and one group of normally closed contact, after pressing rotating forward switch S BT1, rotate forward the energising of switch S BT1 normally opened contact, rotate forward switch S BT1 normally closed contact to disconnect, rotating forward switch S BT1 normally closed contact and the second D.C. contactor KM2 connect, ensure that the first D.C. contactor KM1 is when energising, second D.C. contactor KM2 disconnects, first D.C. contactor KM1, second D.C. contactor KM2 realizes interlocking between the two by the normally closed contact rotated forward on switch S BT1 and reversal switch SBT2.After pressing rotating forward switch S BT1, rotate forward pilot lamp 3 bright, motor rotates forward; Press reversal switch SBT2 again, the normally closed contact of reversal switch SBT2 disconnects, the first D.C. contactor KM1 coil blackout, the main normally closed contact of the first D.C. contactor KM1 on main circuit disconnects, secondary normally closed contact disconnects, and self-locking disappears, and rotates forward switch S BT1 pilot lamp and goes out; Meanwhile, normally closed contact energising on reversal switch SBT2, reset because rotating forward switch S BT1, the normally closed contact rotating forward switch S BT1 closes, second D.C. contactor KM2 coil two ends pass into 24v DC voltage, the main normally closed contact of the second D.C. contactor KM2 on main circuit closes, electric current passes into motor through terminal through position 7, now R phase and T-phase are exchanged, motor reversal, the secondary normally closed contact of second D.C. contactor KM2 closes, the second D.C. contactor KM2 connect one at secondary normally closed contact two ends reverse in parallel with reversal switch SBT2 together after pilot lamp 4.Like this, realize the self-locking of reversal switch SBT2, even if after reversal switch SBT2 reset, motor still reverses.Final phenomenon is, after pressing reversal switch SBT2, rotate forward pilot lamp 3 and go out, reversion pilot lamp 4 is bright, motor reversal; Relay 5
port is control coil voltage input end, wherein
port meets 24V+,
port meets 24V-.
port and
port is respectively the two-port of the first normally opened contact and the second normally opened contact,
port and
port is respectively the two-port of two groups of normally closed contacts.When
when port two ends have voltage to input, the first normally opened contact and the second normally opened contact close, and two groups of normally closed contacts disconnect.When pressing brake switch SBT3,
two ends have voltage to input, and the first normally opened contact and the second normally opened contact are connected, and brake indicating lamp 6 is bright.First normally opened contact and
port input point is connected, and is equivalent to the first normally opened contact and brake switch SBT3 parallel connection.Because brake switch SBT3 is point contact type, after brake switch SBT3 unclamps,
port still can obtain the input voltage of 24V+ from the first normally opened contact, relay 5 still keeps operating state.The principle of work of motor brake block is, when brake block control coil two ends input 24V voltage, brake block action, because friction force makes machine shaft shut down between two brake blocks.Relay 5
port is connected with terminal through position 7, and the 24V-of terminal through position 7 is directly connected with the 24V-output terminal of direct supply 2.24V+ with the 24V-output terminal of terminal through position 7 is connected with the control coil voltage input end of motor brake block.Final phenomenon is, when pressing brake switch SBT3, after unclamping, brake indicating lamp 6 is bright, and motor shuts down.
