Stepper Motor Primer

There are three basic types of step motors: variable reluctance, permanent magnet and hybrid.  A hybrid step motor is a simple low cost means of providing good motion performance.  Step motors are electromechanical devices that work by dividing shaft rotation into discrete distances called steps. Basically, they are brushless motors which include permanent magnet variable … Continue reading Stepper Motor Primer

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 … Continue reading Stepper Drive Questions and Answers – Avoiding Common Mistakes

Improving High-Speed Performance of Hybrid Stepper Motors

Experts pretty much agree that motor torque is proportional to motor current and motor speed is proportional to drive supply voltage, but do you know when this might not be true?  This paper reviews the performance of constant current stepper drive across the motor speed range and the impact of the motor’s inductance, back-EMF and … Continue reading Improving High-Speed Performance of Hybrid Stepper Motors
