Two-Phase Stepper Motors

The PS211 Size-11 stepper motor achieves a nanospeed rate compliant to 2-Phase Nano Stepper Technology.

The PS211 Series reaches up to 200,000 steps/rev at a fine-pitch resolution angle of 0.0018 in. Constructed of polished steel, the motors have magnetic elements and long-lasting durable metal material within both the rotor and stator portion. The motors reach 3.0 to 10 oz-in. holding torque and an amp rating of 0.25 to 1.3 A. Additional features include optional versions of 1.8 to 3.8 V, encoder mounting to executive speed profiles, and both unipolar and bipolar version for design versatility.
