Energizing __________ coil(s) makes the stepper motor jump to a specific position and stop.

Energizing one coil in a stepper motor is sufficient to make the motor move to a specific position and stop. In stepper motors, each coil corresponds to a specific step; thus, when one coil is energized, it creates a magnetic field that aligns with the rotor's position, allowing the motor to step in a precise direction. This stepping mechanism enables accurate control over the motor's position.

While energizing two or more coils can also cause movement, it typically leads to smoother motion and increased torque but is not necessary for achieving a precise positional jump. In many applications, especially when minimal movement is required, controlling just one coil is a straightforward method to achieve positional accuracy without the need for the additional complexity of managing multiple coils.
