NEMA 17 48mm Hybrid Stepper Motor 1.8° 1.4A D Shaft 7.6 kg·cm Torque

NEMA 17 48mm Hybrid Stepper Motor KC-42HYB48

The KC-42HYB48 is a nema 17 48mm hybrid stepper motor developed around a 42 mm frame and 48 mm motor body. Its 2-phase structure, 1.8° step angle, D-shaft configuration and 20 mm output shaft support controlled rotary positioning in automation equipment, CNC mechanisms, 3D printers and other motion assemblies. For engineers comparing a 48mm nema 17 stepper motor, the body length should be evaluated together with available installation depth, required holding torque, driver current and shaft interface rather than as an isolated dimension.

KC-42HYB48 Electrical And Performance Specifications

Electrical Selection Considerations

The specified winding makes this nema 17 1.4a stepper motor suitable for use with a bipolar current-controlled driver selected for the required operating speed and supply voltage. A nema 17 1.8 degree stepper motor provides 200 full steps per revolution before microstepping is applied. The 7.6 kg·cm holding torque identifies the stationary torque capability of this winding configuration; available running torque decreases as speed rises and should be verified against the actual acceleration profile and load inertia.

KC-42HB-48L values above are retained as a separate product-image reference specification and should not be interpreted as electrical values for KC-42HYB48. Driver settings should follow the exact motor model supplied.

NEMA 17 48mm D-Shaft Mechanical Dimensions

Performance Advantages

• The 48 mm body provides a higher holding-torque configuration within the 42HYB frame family without changing the basic NEMA 17 mounting envelope.
• A D-shaped output shaft provides a defined mechanical interface for couplings, pulleys and other components where resistance to shaft-to-hub slip is required.
• The 1.8° step format is compatible with common bipolar stepper drivers and can be combined with microstepping when lower incremental motion and reduced vibration are required.
• The 31 ± 0.1 mm mounting-hole spacing and 4 × M3 pattern provide clear mechanical references for equipment integration and replacement evaluation.
• Multiple 42HYB body lengths and shaft dimensions allow the motor series to be matched to different torque, installation-depth and coupling requirements.

Engineering Application Notes

A nema 17 d shaft stepper motor is commonly selected where the output connection must maintain a defined angular relationship with a pulley, coupling or drive element. For a 48mm nema 17 d shaft configuration, enclosure clearance should account for both the 48 mm motor body and the specified shaft projection. A 5mm d shaft nema 17 stepper motor may also be configured within the mechanical options shown in the drawing when the shaft requirement is confirmed for the production version.

The KC-42HYB48 can therefore be evaluated as a nema 17 bipolar stepper motor and nema 17 hybrid stepper motor for positioning systems that require the NEMA 17 mounting format with increased motor length. Engineers searching for a 42mm hybrid stepper motor or 42mm 48mm stepper motor should verify driver current, operating speed, available torque at speed, thermal conditions and mechanical load before final selection.
