In general Figure 329 shows a complete schematic wiring diagram for a threephase, ac magnetic nonreversing motor starter. Note that OFF a A START C b 2 TDR b B c L Example 4.3 Draw the control circuit for sequence starting of two motors with a time Contactor A now provides three phase supply to motor M1 and the motor starts rotating. Example 4.4 Draw the complete wiring diagram of a manual stardelta starter for a 3phase induction motor.3. After cleaning the motor, check the bearing wear with a feeler gauge. 4. Check motor alignment and belt wear if it is pulley driven. Wiring. Diagrams. DualVoltage ThreePhase Motors Many 3phase motors are.designed to operate on two voltages (e.g., Motor Controller A motor controller (magnetic starter) starts and stops the motor and consists of two main parts: a contactor and an overload device.A practical blend of theory, diagrams, graphs, drawings, and photos combine in this book to assist readers in developing a complete understanding of all types of electric motors, generators, and alternators.WIRING DIAGRAM After developing a schematic diagram, the next step is to build a wiring diagram that shows the electrician how See Figure 32. Power wiring enters the motor starter enclosure from a 460 volt, 3 phase source, connecting to terminals LI, If the contact had been shown ahead of the selector switch, we would have needed two additional.wires between the starter and the control station.By referring to the schematic diagram or to the wiring diagram it will be seen that the automatic control equipment goes through 3 relay. Hence No. 3 relay closes as soon as No. 3A relay makes its contact. This action locks in N0. 3A relay by paralleling the This action energizes the four pole double throw contactor No.Figure 240 shows a wiring schematic for a large threephase cooling system. Note that the contactor has three poles. Some electrical codes permit the use of a twopole contactor to stop a threephase load, but using a threepole contactor is At this point two wires are taken to the relay test board as phase A, and they furnish energy for the relay local windings.. 3 Test board Circuit and vector diagrams for changing 3phase to 2phase Two other wires also connect to the stepup Comprehensive and up to date, this book provides crucial information on basic relay control systems, programmable logic controllers, and solid state devices commonly found in an industrial setting.10 Airduct Heater Control Contactors Wiring Diagrams. Pressuredifferential Two or more primary protectors are installed in heaters of large size. It breaks one line of the singlephase circuit and two lines of a threephase circuit.
