  • Stepping Motors
  • Full step 0.72 resolution, half step 0.36 resolution, and as low as 0.0029 resolution with micro-step.
  • For locations with limited space and where a high-speed, high-torque motor is required. Ideal for indexing and other rapid positioning applications. No maintenance or communication problems as found with servo motors. Each stepping motor requires a motor driver and motion controller (not included, sold separately on this page).
