D. Load torque
Answer:D
What is the primary factor that determines the maximum achievable speed of a stepper motor?
A. Step angle B. Supply voltage C. Rotor inertia D. Load torque
Explanation: The maximum achievable speed of a stepper motor is primarily determined by the load torque it needs to overcome. Heavier loads or higher inertia require more torque, which can limit the motor’s maximum speed.
