Reversing starters are designed to allow the motor to operate in both forward and reverse directions. Each type of motor listed can indeed be paired with a reversing starter, as follows:

A direct current (DC) motor can easily be reversed by changing the polarity of the supply voltage, which is facilitated by a reversing starter. This capability makes DC motors ideal for applications where precise control over direction is necessary.

Single-phase alternating current (1Ø AC) motors can also be set up with reversing starters, although reversing these motors often requires switching connections on the starter itself. This indicates that these motors, though less commonly used for applications requiring frequent direction changes, can still function in a reversing capacity when paired with the appropriate starter.

Three-phase alternating current (3Ø AC) motors are very commonly used in industrial settings and benefit significantly from reversing starters. These motors can be reversed by swapping any two of the three supply leads, making them particularly well-suited for operations where bidirectional motion is essential.

Thus, a reversing starter can be utilized with all the motor types mentioned, confirming the answer that all of these motor types can be effectively paired with reversing starters in various applications.
