Specifications:
NEMA Size 17 stepper motors are available with a 0.9° step angle, offering a wide selection and cost-effective solutions. Custom windings can be provided at no additional cost. The motors are available in unipolar and bipolar configurations with varying dimensions and performance characteristics.

Unipolar Motor Specifications:
Motors are categorized by dimension 'A' with models 4209S, 4209M, and 4209L. Each model has different amperage per phase, torque (in oz-in and N-m), resistance, inductance, inertia, weight, and number of leads. For example, the 4209S-01 model has a torque of 22.2 oz-in and a resistance of 4.8 Ohm/Phase.

Bipolar Motor Specifications:
Similar to unipolar, bipolar motors are also categorized by dimension 'A' with models 4209S, 4209M, and 4209L. They have different specifications for series and parallel configurations, affecting amperage per phase, torque, resistance, and inductance. For instance, the 4209S-01S model has a torque of 31.0 oz-in and a resistance of 9.6 Ohm/Phase.

Torque Curves:
The document includes torque curves for various models, showing the relationship between speed (in pulses per second and revolutions per second) and torque (in oz-in and N-m). These curves are essential for understanding motor performance under different operating conditions.

Additional Information:
Users are advised to complete an application data sheet for different windings. The power supply voltage can vary as long as the driver output current is controlled at the rated current. For further details on bipolar torque curves and operating temperatures, users should contact Lin Engineering or refer to additional documentation.
