Which of the following is a component of a reversing magnetic motor starter?

A reversing magnetic motor starter includes several key components that enable it to change the direction of motor rotation. The reversing coil is an essential component of this system. It is specifically designed to reverse the polarity of the current flowing through the motor windings, thereby allowing the motor to rotate in either direction depending on whether the forward or reverse action is activated.

In a reversing magnetic starter, when one coil is energized, it will engage the motor to run in one direction. When the reversing coil is energized instead, it switches the connections of the motor, allowing it to run in the opposite direction. This functionality is crucial for applications where the motor needs to alternate between different operational modes or directions, such as in material handling systems.

The other components, while important in their own contexts, do not play a direct role in the reversing function of the motor starter. A forward switch typically controls motion in one direction, a safety relay acts to ensure safe operation and protect against faults, and a deceleration module is related to controlling the speed and stopping of the motor rather than reversing its direction. Thus, the reversing coil stands out as the key component that specifically enables the motor starter to reverse the operation of the motor.
