Unbeatable Value


The 4118 Series stepper motor is our best-selling stepper motor for numerous reasons: it delivers unbeatable balance between high performance and low price; it offers a high range of customizations; and its wide performance range makes it ideal for many applications.

Versatile performance


The 4118 Series stepper motor is a good fit for wide range of applications. The series is available in many stator lengths, from 1.34” (34mm) to 2.34” (59.4mm). Holding torque ranges from 44 oz-in (0.3 Nm), up to 115 oz-in (0.88 Nm). High range of dynamic torque with speed up to 1200 RPM. And a large selection of windings to meet your specific requirements.

Lin Engineering Quality


Every component and every motor that leaves our facility must meet our mean value control. Additionally, every motor is tested to meet the required electrical specifications (resistance, inductance, leakage), torque specifications (holding and detent torque), mechanical specification (front shaft extension dimension and overall body length), and any other special feature specification. We want to ensure that your motor delivers the precise specifications you require. This gives you confidence that your motors will perform consistently and reliably within your application.
