The basic wiring diagram is 1 7 to one phase 2 8 to second phase 3 9 to third phase and 4 5 6 hooked together to be the external star. W2 cj2 ui vi wi w2 cj2.

3 Phase Nine Wire Motor On 3 Phase W Bastard Leg System Electric Motors Generators Engineering Eng Tips

There will be a voltage from both voltage source leads to the point as shown in fig.

Dual voltage 3 phase motor wiring diagram 9 leads. A three phase motor must be wired based on the diagram on the faceplate. 3 phase motor wiring diagram 12 leads 3 phase 6 lead motor wiring diagram elegant awesome 12 lead 3 phase motor wiring diagram electrical. In addition all three have six internal coils although their internal connections differ widely.

Another variation of wiring configuration for a 9 leads motor connection apart from the 9 leads delta connection is the 9 leads star wye wiring. Split phase motor dual voltage reversible rotation capacitor motor single phase wiring diagrams always use wiring diagram supplied on motor nameplate. Three phase dual voltage motors come in three basic configurations.

This video will walk you through the standard winding terminal designations proper wiring connections and expected winding voltages for a dual voltage 3 phas. If the point is one of the leads attached to the power source there will be a voltage read from one source lead to the idle lead and none from the other source lead fig. The 3 phase ac source line voltage l1 is connected to the motor terminal 1 6 7 line voltage l2 to motor terminal 2 4 8 and line voltage l3 to motor terminal 3 5 9 refer to above drawing.

A wiring diagram is a streamlined conventional pictorial depiction of an electrical circuit. 6 23 if the right leads are selected. Delta connected 9 lead motor.

All 9 leads motors are most commonly made for dual voltage application this means that the motor was manufactured specifically for dual voltage operation which can be connected in either. Always use wiring diagram supplied on motor nameplate colored leads are only applicable on the new rolled steel motor lines. That being said there is a wide range of different motors and what you have on hand can be completely different.

It shows the elements of the circuit as simplified shapes and the power as well as signal connections between the gadgets. The first step is to figure out the voltage of your phases. It is of utmost importance to firstly understand the internal wiring configuration of a 9 leads ac induction motor before doing the actual wiring connection.

In the united states for low voltage motors below 600v you can expect either 230v or 460v. Delta connected 9 lead wye y connected 9 lead wye connected 12 lead all three types can be wired for either 240 or 480v ac. Identifying leads of a nine lead three phase motor.
