R1 coil r2 similarly for b phase and y phase. Connect the voltmeter leads to 3 6 connect the battery terminal to 7 and flash the terminal to 9. In a 3 wire motor three wires are drawn out from the winding of the motor. Pay no attention to the very slight readings on the ohm meter as that is continuity thru the windings. Always use wiring diagram supplied on motor nameplate. Obtaining these continuity readings confirms that the motor is internally configured for a star wye connection. Three wire motor winding connection diagram. In this lesson we ll learn to read and interpret motor connection diagrams and determine the electrical relationship of the stator windings using motor conne. Connect the voltmeter leads 2 5 connect the battery terminal to 9.

Now you have 6 winding ends r1 r2 y1 y2 b1 b2. Three wire motor winding connection diagram. Home electrician tutorials 3 phase wiring for dummies understanding motor connections. Connect the voltmeter leads 2 5 connect the battery terminal to 9. They can now be labeled. Always use wiring diagram supplied on motor nameplate.
1 ohm meter 2 6 or 12 volt battery 3 t. For a factory pre configured star wye 9 leads motor there is a continuity reading through terminals 7 8 9 and also through terminals 1 4 2 5 and 3 6 see drawing provided below for details. Connect the voltmeter leads 2 5 connect the battery terminal to 9. Three wire motor winding connection diagram. R1 coil r2 similarly for b phase and y phase. Connect the voltmeter leads to 3 6 connect the battery terminal to 7 and flash the terminal to 9. Obtaining these continuity readings confirms that the motor is internally configured for a star wye connection. Steve discusses how to identify unmarked 9 lead delta connection on a motor. Among these one wire is common wire and the other wire is of the running winding and the third wire is drawn in the starting winding. In a 3 wire motor three wires are drawn out from the winding of the motor.
Obtaining these continuity readings confirms that the motor is internally configured for a star wye connection. L1 to t1 l2 to t2 l3 to t3 t4 to t7 t5 to t8 and t6 to t9. R1 coil r2 similarly for b phase and y phase. Three wire motor winding connection diagram. Home electrician tutorials 3 phase wiring for dummies understanding motor connections. Now you have 6 winding ends r1 r2 y1 y2 b1 b2. Group each lead with the others to which it has continuity. 1 ohm meter 2 6 or 12 volt battery 3 t. Yes it is possible to connect 3 phase motors in star as well as delta connection if you have winding ends noted well i e r phase. To identify 3 6.
The other 9 wires would be connected as in a 9 wire motor note in a 9 wire motor the equivalent of t10 t11 and t12 are internally connected together. Obtaining these continuity readings confirms that the motor is internally configured for a star wye connection. They can now be labeled. Three phase systems are extremely common in industrial and commercial settings. Group each lead with the others to which it has continuity. 3 phase wiring for dummies understanding motor connections. With an upscale reading the lead of the volmeter will be on 3 and the voltmeter will be on 6. Connect the voltmeter leads 2 5 connect the battery terminal to 9. R1 coil r2 similarly for b phase and y phase. Delta connection we will need.
3 phase wiring for dummies understanding motor connections. In a 3 wire motor three wires are drawn out from the winding of the motor. Delta connection we will need. The blue wire is connected directly to the neutral wire coming from the main power supply coming from the back and the red wire and black.
