Stepper Drive Questions and Answers – Avoiding Common Mistakes

Question:  What is the most common mistakes that engineers make when specifying and working with stepper drives?

Answer:  Believing that a motor will achieve the data sheet’s rated speed-and torque when it is matched to “any” driver.  Just like a servo, the stepper motor’s stall torque, rated torque, and rated speed are all dependent as much on the drive and motor being matched as they depend on the available voltage and current.  A performance curve (speed-torque-curve) with a matched drive is the most reliable reference.   Also, a motor’s stall torque is not an indication of the torque a motor can generate while moving — especially during acceleration and deceleration where higher torque is required…
