B. Holding torque
C. Rotor inertia
D. Backlash
Answer:A
Which motor characteristic describes the ability of a stepper motor to maintain its position without external holding torque?
A. Detent torque B. Holding torque C. Rotor inertia D. Backlash
Explanation: Detent torque refers to the ability of a stepper motor to hold its position without the need for external holding torque. It arises from the interaction between the stator and rotor magnetic fields when the motor is not energized.
