Questions & Answers

What does a stepper motor system consist of?
  • Controller: capable of generating step pulses and direction signals for the driver.
  • Driver: converts the controller command signals into power to energize the motor windings.
  • Stepper Motor: electromagnetic device that converts digital pulses into mechanical shaft rotation.
What is stepper motor resonance?

Resonance is an unstable condition when running a step motor. Resonance usually occurs between 2-4 rev/sec and can be alleviated in most situations by putting a load on the motor, changing from full stepping to half or microstepping, or increasing your acceleration through the resonance zone.

Are stepper motors AC or DC?

Stepper motors are generally considered to be asynchronous (AC) motors. While stepper motors are largely the same as brushless DC motors (BLDC motors), they differ in their intended use. Stepper motors operate in steps whereas a BLDC motor provides smooth motion.

  • Stepper Motor vs. Brushless Motor

    Feedback Brushless servomotors run in closed-loop mode, requiring a feedback device. Stepper motors do not require feedback. Accuracy If an unexpected load is encountered, a brushless motor will correct its position. A stepper motor will not recognize when its torque limit has been exceeded. Speed Brushless servomotors can run at much higher speeds (3000 to…

  • What is a Stepper Motor Driver?

    There are two common systems of driving a stepper motor: constant current drive and constant voltage drive. The circuitry for the constant voltage drive is simpler, but it is relatively more difficult to achieve torque performance at high speeds. The constant current drive, on the other hand, is now the most commonly used drive method,…

  • 3 Excitation Modes of Stepper Motor

    There are three excitation modes that are commonly used with the stepper motor. These stepper motor modes are the full‐step, half‐step‐ and microstep. Stepper Motor ‐ Full‐Step In full‐step operation, the stepper motor steps through the normal step angle, e.g. 200 step/revolution motors take 1.8 steps, while in half‐step operation 0.9 steps are taken. There…
