26M048B Can Stack Stepper Mini Motor
26M048B
The 26M048B is a 7.5 degree step angle can stack that can provide up to 1.5 oz-in (10.6 mNm) of holding torque in a 26 mm frame size. The 48 steps per revolution allows for more refined positioning resolution. It is available in 5 or 12 volt windings, and in unipolar or bipolar designs.
