Lightweight and compact – short body length, minimal footprint.
High torque – up to 3× overload capability.
High speed – smooth operation up to 6,000 rpm.
Excellent stability and low cogging torque – enabled by a new electromagnetic design with a 10‑pole/12‑slot configuration.
High protection and long service life – stator coils are integrally potted (encapsulated).
Versatile compatibility – supports incremental and absolute magnetic encoders.
Cost‑effective – high power density for the price.
Rated voltage (D Series): 220 V – 380 V
Typical applications: collaborative robots and heavy‑load six‑axis robots.
