Torque performance
TEST CONDITION: Measured at 24 VDC using DS-OLS8-FRS4 bipolar chopper drive at rated current (RMS). Motor torque varies with supply voltage and drive settings; allow a safety margin (recommendation: 50% for system design) when selecting the motor.

Options and customization
Available options include hollow-shaft encoder assemblies (single-ended or differential outputs), custom windings and shaft modifications. Contact the supplier for available resolutions, output mappings and lead times.

Documentation
Datasheets, dimensional drawings and torque/speed performance curves are provided to support technical selection and integration.
