Permanent & Disc Magnet Stepper Motors

26M048D - Tin Can Permanent Magnet Stepper Motor

The 26M048D is a 7.5 degree step angle can stack with high strength magnets that can provide up to 2.05 oz-in (14.5 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. Mclennan holds stock of various configurations in the UK for immediate delivery. For technical assistance and details of value added assemblies, including gearboxes and wiring / connector options please contact our sales and applications support team.
