C‑Series Servo Motors – Key Features
Lightweight and compact – short body length with a small footprint.
High torque capability – supports up to 3× overload capacity.
Low current draw – rated current is lower than that of comparable models in the same series.
Highly flexible – readily accommodates a wide range of non‑standard customisations.
Broad encoder compatibility – supports multiple encoder types, including optical incremental, magnetic incremental, absolute, and resolver.
Rated voltage: 24 V – 72 V DC
Typical applications: industrial robots and material‑handling robots.
