NEMA 17 Rotary Stepper Motor Size 17 / 42 mm
DINGS’ 5-phase NEMA 17 hybrid rotary stepper motors deliver fine 0.72° step resolution in a 42 mm frame. Like a finer-toothed gear, the 5-phase design divides each revolution into smaller motion increments for smooth, accurate rotary positioning.
5-Phase NEMA 17 Rotary Stepper Motor Overview
The Size 17 5-phase hybrid rotary stepper motor family includes four standard lengths: 34 mm, 41 mm, 49 mm, and 61 mm. All models use a 5-phase design with a 0.72° step angle and 1.8 A rated current.
Compact Frame
42 mm frame size for precision equipment that needs higher torque than the smaller 28 mm platform.
Fine Step Resolution
0.72° step angle supports smooth, precise incremental positioning.
Two Motor Lengths
34 mm, 41 mm, 49 mm, and 61 mm stack lengths available for different torque requirements.
Customizable
Available with application-specific shaft, cable, winding, and integration options.
