A motor is connected as follows: L1 to T1, L2 to T2, and L3 to T3. To reverse the motor, the leads need to be connected in the following way:

Select one:

A. L1 to T3, L2 to T1, and L3 to T2

B. L1 to T2, L2 to T3, and L3 to T1

C. L1 to T3, L2 to T2, and L3 to T1

D. L1 to T1, L2 to T2, and L3 to T3

Answer :

To reverse the direction of a three-phase motor, you typically need to swap any two of the phase connections. This changes the sequence in which the phases are applied to the motor, which reverses the direction of the motor's rotation.

Let's look at the given options to determine which one will reverse the motor:

1. Current connection:
- L1 to T1
- L2 to T2
- L3 to T3

2. Options to reverse the motor:
- Option a: L1 to T3, L2 to T1, and L3 to T2
- Here, L1 and L2 connections are swapped.
- Option b: L1 to T2, L2 to T3, and L3 to T1
- Here, L1 and L3 connections are swapped.
- Option c: L1 to T3, L2 to T2, and L3 to T1
- Here, L1 and L3 connections are swapped, just like option b, but in a different sequence.
- Option d: L1 to T1, L2 to T2, and L3 to T3
- This is the original setup with no changes.

To reverse the motor, swapping any two of the three phases will achieve that. Options 'a' and 'b' swap the leads, thus effectively reversing the motor.

However, among all the options, it seems that:
- Option a: L1 to T3, L2 to T1, and L3 to T2 is a common configuration that can reverse the motor by swapping two phases, L1 and L2.

Therefore, the correct option to reverse the motor is a: L1 to T3, L2 to T1, and L3 to T2.
