NEMA 17 Stepper Motor With Encoder Series, Built-In Driver, 48mm, 2A
NEMA 17 Stepper Motor With Encoder And Built-In Driver
The KC-42HB-48L is a 42 mm frame nema 17 stepper motor with encoder designed around a 48 mm motor body, integrated driver configuration, and 5 mm D-shaft. Its 2-phase bipolar architecture and 1.8° step angle provide a conventional mechanical interface for positioning equipment, automated mechanisms, instrument stages, and other systems requiring controlled incremental motion. The integrated configuration can reduce the number of separately mounted control components when compared with a motor, external driver, and encoder installed as independent assemblies.

Mechanical Dimensions And Related Model Data
The 42 mm square mounting format supports standard NEMA 17 mechanical integration, while the 48 mm body length provides additional stator volume compared with shorter frame variants. A 20 mm shaft extension and 5 mm D-shaft give designers a defined interface for couplings, pulleys, lead mechanisms, or custom transmission components. The related KC-42HYB48 uses the same 42 mm × 48 mm mechanical envelope but has different winding and torque data, so its electrical specifications should be treated as a separate model rather than substituted for KC-42HB-48L.

Engineering Advantages
- Integrated driver and encoder architecture reduces separate component mounting requirements and can simplify wiring layout inside motion-control assemblies.
- The nema 17 bipolar stepper motor format uses a familiar 42 mm mounting envelope for integration into existing mechanical platforms.
- A 1.8° step angle supports controlled incremental positioning while remaining compatible with common stepper-control methods.
- The 5 mm D-shaft and 20 mm extension provide a defined mechanical connection for couplings, pulleys, and transmission components.
- 12 V and 24 V drive options allow the KC-42HB-48L to be evaluated for different control-system supply architectures.
- The two related 48 mm models are listed separately so electrical resistance, current, inductance, and holding torque are not incorrectly combined.
NEMA 17 Encoder Integration Considerations
For equipment using a nema 17 encoder, the feedback signal can support position verification when the surrounding controller and firmware are configured for the encoder interface. The KC-42HB-48L is specified as a nema 17 stepper motor with built in driver and encoder, making it relevant where designers want the motor, drive electronics, and feedback function organized as one integrated motor assembly. Its 2 A phase rating, 42 mm frame, and 48 mm body should still be checked against thermal conditions, acceleration requirements, load inertia, mounting space, and the selected power supply before final system integration.
