SP17H50 42 mm 0.72° Five-Phase Stepper Motor – Single Shaft
Five-Phase Stepper Motor
SP17H50 is a 42 mm 0.72° five-phase stepper motor with single-shaft construction, 0.3–0.5 N·m holding torque and 1.8 A/phase rated current.
Positioning accuracy
High torsional rigidity and constant torsional backlash over the entire gearbox service life ensure consistently high performance
Compactness
High torque density thanks to high performance and short design
Low maintenance
Highest quality standards for a long service life and extended maintenance intervals
Technical data
Fine-step five-phase rotary motion
0.72° five-phase positioning in a 42 mm frame
The SP17H50 series combines a 0.72° step angle with a single-shaft 42 mm frame. Three motor lengths provide 0.3, 0.37 or 0.5 N·m holding torque at the same 1.8 A/phase rated current. This 42 mm series is also available with optional vacuum-compatible customization for operating pressures down to 1 × 10⁻⁴ Pa.
Three torque levels
Select the 40, 48 or 60 mm body for 0.3, 0.37 or 0.5 N·m holding torque.
Single-shaft integration
A 5 mm output shaft, 31 mm mounting-hole spacing and 500 mm leads support straightforward machine installation.
