Technical data
Continuous-duty brushless rotary motion
57 mm brushless DC motors for precise machine integration
The SP57 series provides three 24 V configurations with Hall feedback, 3,000 rpm rated speed and rated torque from 0.119 to 0.33 N·m. Rated output power extends from 37.4 to 103.7 W.
Hall feedback
Three Hall signals support 120° electronic commutation; an incremental encoder can be evaluated as an additional feedback option.
S1 duty
All three models use a star-connected winding, five pole pairs and documented continuous-duty operating data.

System integration
Match motor length and winding data to the required load
The SP57 series shares a 24 V, 3,000 rpm rated operating point across three motor lengths. Select the model by continuous torque, rated power, current and installation envelope.
- Confirm the operating point against the model-specific performance curve
- Use a compatible 120° electronic commutation drive and Hall feedback interface
- Verify shaft load, S1 duty and thermal conditions in the final assembly
