Introduction

The ORM 245K-1 comes in a standard NEMA 17 mounting size. Sporting a low-vibration, low-noise design, the motor significantly outperforms other motors its size. It features a keyed shaft for easy, slip-free attachment of your load.

The motor has a 1.8° step size, for 200 steps per revolution. In half-step mode the step size becomes 0.9° for 400 steps/rev. Micro-positioning in 0.18° or smaller steps is possible when used with our microstepping drivers, which can produce from 10 to 256 microsteps for each full step. Absolute positioning accuracy is rated to be within ±5% of one full step.
