Permanent & Disc Magnet Stepper Motors

42L048D - Tin Can Permanent Magnet Stepper Motor

Tin Can Permanent Magnet Stepper Motor

The large rotor and neodymium magnets of the 42L048D provide up to 18.5 oz-in (131 mNm) of holding torque and is optimal for high torque applications. The 48 steps per revolution results in a 7.5 degree step which increases the positional 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.
