NEMA 11 Rotary Stepper Motor Size 11 / 28 mm
DINGS’ 5-phase NEMA 11 hybrid rotary stepper motors deliver fine 0.72° step resolution in a compact 28 mm frame. These motors are suited for precision positioning applications that require smooth motion, compact size, and reliable torque output.
5-Phase NEMA 11 Rotary Stepper Motor Overview
The Size 11 5-phase hybrid rotary stepper motor family includes two standard lengths: 33 mm and 52 mm. Both models use a 5-phase design with a 0.72° step angle and 1.2 A rated current.
Compact Frame
28 mm frame size for tight machine layouts and compact precision mechanisms.
Fine Step Resolution
0.72° step angle supports smooth, precise incremental positioning.
Two Motor Lengths
33 mm and 52 mm stack lengths available for different torque requirements.
Customizable
Available with application-specific shaft, cable, winding, and integration options.
