Question

The number of pulses applied to a Stepper motor determines the

• A. Speed of rotation
• B. Torque produced
• C. Total angle or distance of rotation
• D. Direction of rotation

Hint:

In a stepper motor, number of pulses controls angular displacement, and pulse frequency controls speed.

Answer 1

The Correct Option is C

Concept: A stepper motor rotates in fixed angular steps when input pulses are applied.

Step 1: Each input pulse moves the rotor by one step angle.

Step 2: If more pulses are applied, the rotor rotates through more steps.

Step 3: Therefore, total angular displacement depends on number of pulses.

Step 4: Speed depends on pulse frequency, not simply on total number of pulses. Hence, number of pulses determines: \[ \boxed{\text{Total angle or distance of rotation}} \]
