A bidirectional motor requires which arrangement of starters?

A bidirectional motor requires which arrangement of starters?

• A. One forward starter
• B. One for forward and one for reverse
• C. A single dual-direction starter
• D. A mechanical brake

Answer: (B)

To reverse a motor, you must switch the connections that deliver the supply so the motor windings receive the forward or the reverse arrangement. This is done with two separate starters: one that energizes the circuit for forward rotation and another that energizes the circuit for reverse rotation. Having two distinct starters makes it easy to control direction and, with interlocking, prevents both directions from being energized at the same time, which could cause a short or a dangerous cross-connection. A brake is a separate device used to stop or hold the motor, not to control its direction. A single forward starter alone can only run the motor in one direction, and a dual-direction starter is not the standard safe setup without proper interlocking.
