Overview
The EYOU PH17 Robot Joint Motor is an internal-rotor torque motor for robotic joints, with a cylindrical 80 mm housing, 14 mm through bore, dual magnetic encoder, and selectable 51 or 101 gear ratio.
Select the PH17B version with brake or PH17N version without brake, then choose the 51 or 101 gear ratio. The 51 ratio provides 60 rpm rated speed and 22 N·m rated torque; the 101 ratio provides 30 rpm and 38 N·m.
Features
- Internal-rotor torque motor design with a cylindrical housing and circular output flange.
- 14 mm through bore and 80 mm nominal diameter.
- Dual magnetic encoder with 19-bit encoder accuracy.
- Selectable PH17B version with brake or PH17N version without brake.
- Selectable gear ratios of 51 and 101.
- The product views include circular mounting flanges, radial hole patterns, and multiple electrical connector housings.
