This series is three-phase closed-loop brake-type stepper motors, divided into two sub-series with 1000-line incremental encoders and 17BC absolute encoders, covering frame sizes of 60/86/110/130mm with a unified step angle of 1.2°. The static torque ranges from 2.6-35N·m and rated current from 1.5-6.8A. Incremental encoder versions match 3HCS2208H drives, while absolute encoder versions match corresponding 3HCS22xx-17BC series drives. Built-in brake structure realizes power-off self-locking. Different frames have exclusive body length and shaft specifications, non-standard shaft customization is available, suitable for three-phase closed-loop stepper control scenarios with braking requirements.
