LDO NEMA17 Motor LDO-42STH48-2804AH

**55mm shaft motor images coming soon

The LDO-42STH48-2804AH Super Power Motor is a high-quality stepper motor from LDO Motors. It is part of the Super Power series, which is the evolution of the speedy power series and is a part of the high-temperature edition with a Class H 180c rating. The motor has a 1.8° step angle, 200 steps per revolution, and 24mm shaft. It is used in various applications such as 3D printers, CNC machines, and robotics. These motors offer high torque, power rating, and speed.

This motor is available in both 20mm and 55mm shaft lengths.

** For standard Voron printers 20mm shaft is all that is required.

55mm shaft length is better if you want to build an AWD system like the Monolith Gantry by CloakedWayne or want the extra length to reinforce motor shaft with bearings for a 9mm belt.

If you do not need a high-temperature version of this motor, the LDO-42STH48-2804AC Motor is also available here
