Specifications
The document provides detailed specifications for step motors, focusing on high torque and high step accuracy. It includes both unipolar and bipolar motor configurations with various dimensions and model numbers. Key specifications include rated current (Amps/Phase), holding torque (oz-in and N-m), resistance (Ohms/Phase), inductance (mH/Phase), inertia (oz-in²), weight (Lbs.), and the number of leads.

Unipolar Motors
Unipolar motors are available in three dimensions: 1.74” (44.2 mm), 2.20” (55.9 mm), and 3.08” (78.2 mm). Each dimension has specific models with varying current, torque, resistance, and inductance values.

Bipolar Motors
Bipolar motors also come in the same three dimensions with different models. They offer higher holding torque and different electrical characteristics compared to unipolar motors.

Customization Options
The motors can be customized for maximum torque, cables and assemblies, shafts, drivers, and controllers. Specific pages are referenced for more detailed information on these customizations.

Additional Information
The document advises completing an application data sheet for different windings and contacting Lin Engineering for additional bipolar torque curves. It notes that specifications are approximations and subject to change without notice. Operating temperatures and further details are available on other pages.

Available Options
Options for shafts, cables and assemblies, encoders, and drivers & controllers are available, with specific pages provided for more information.
