Specifications:
The document provides detailed specifications for NEMA Size 17 step motors, highlighting their cost-effectiveness and availability of custom windings at no additional cost. The motors are available in both unipolar and bipolar configurations, with various models offering different dimensions, torque, resistance, inductance, inertia, and weight.

Unipolar Motors:
- Models range from 0.9" to 1.88" in dimension "A".
- Torque ranges from 4.1 oz-in to 30.0 oz-in.
- Resistance varies from 3.3 Ohm/Phase to 42.3 Ohm/Phase.
- Inductance ranges from 1.7 mH/Phase to 28.8 mH/Phase.

Bipolar Motors:
- Models range from 0.9" to 1.88" in dimension "A".
- Torque ranges from 8.4 oz-in to 42.0 oz-in.
- Resistance varies from 0.5 Ohm/Phase to 10.2 Ohm/Phase.
- Inductance ranges from 0.8 mH/Phase to 10.2 mH/Phase.

Procedures and Recommendations:
- Users are advised to complete an application data sheet for different windings.
- Power supply voltage can vary as long as the driver output current is controlled at the rated current.
- Additional bipolar torque curves are available upon request.
- Specifications are subject to change without notice.
- Operating temperatures are detailed on page 94.

Torque Curves:
The document includes torque curves for various models, illustrating the relationship between speed (in pulses per second and revolutions per second) and torque (in oz-in and N-m) for both unipolar and bipolar configurations.
