Indicate the correct terminal markings for a star-delta motor on Figure 29–9.

Chapter 29, Problem 1SQ, Indicate the correct terminal markings for a star-delta motor on Figure 299. FIG. 299

FIG. 29–9

Expert Solution & Answer
Check Mark
To determine

Specify the correct terminal markings of the star-delta motor in Figure 29-9.

Explanation of Solution

Star-delta motors:

The construction of star-delta motor is similar like standard type of squirrel cage motors. In star-delta motor, two ends of each of the three windings are brought out to terminals.

Refer Figure 29-9 in the textbook for the star-delta motor circuit. Modify the figure by mentioning the all-terminal markings and the modified circuit diagram as shown in Figure 1.

Electric Motor Control, Chapter 29, Problem 1SQ

In Figure 1, T1, T2, T3, T4, T5, and T6 are the six leads of motor.

Conclusion:

Thus, the correct terminal markings are mentioned in the star-delta motor.
