0.72° step angle
Five-phase construction provides 500 full steps per revolution for fine incremental positioning.
High torsional rigidity and constant torsional backlash over the entire gearbox service life ensure consistently high performance
High torque density thanks to high performance and short design
Highest quality standards for a long service life and extended maintenance intervals
SP24H5055-240-5AC-FB combines a 0.72° five-phase motor with a 24 V, 2 N·m brake, a 500 mm phase cable and a 500 mm brake cable. A vacuum-compatible motor configuration is also available for operating pressures down to 1 × 10⁻⁴ Pa; brake and cable specifications must be confirmed separately for the selected vacuum application.
Five-phase construction provides 500 full steps per revolution for fine incremental positioning.
The 87.5 mm motor body is rated for 2.1 N·m holding torque at 2.4 A per phase.
The configuration includes a 24 V, 2 N·m brake with separate 500 mm motor and brake cables.
