Question

A stepper motor having a resolution of 300 steps/revolution and running at 2400 rpm has a pulse rate of ______ pps.
1. 4000
2. 8000
3. 6000
4. 10000

Answer 1

Correct Answer - Option 3 : 6000

Concept:

Pulse per second is mathematically given as

PPS = (rpm/120) × (number of steps per minute)

Calculation:

The speed of motor = 2400 rpm

By converting into rps,

= 2400/60 = 40 revolutions per second

Resolution of motor = 300 steps/revolution

Steps per second = revolutions per second × number of steps/revolution

= 40 × 300 = 12000

Pulses per second = 6000
