Features And Benefits

Get up to 35% more torque versus a standard motor of the same size.

4418 Series NEMA 17 size stepper motors provide great length to torque ratio. This motor is perfect for applications with limited space, which require more torque than what a standard motor can provide. The 4418 delivers up to 35% more torque than a standard stepper motor of the same length.

How did we do it?

The design of the 4418 Series stepper motor is similar to our 4118 Series motor. It utilizes an 8-pole stator to maximize the torque output. However, the difference is in our patented low profile end cap (end bell) with an integrated bearing. This low profile end cap allows us to use a larger rotor, with larger magnetic surface, which produces more torque, while retaining short motor length.
