The R911276731 (MHD112B-058-PG0-RN) is a synchronous servo motor designed for industrial automation applications. It operates with a rated input current of approximately 27.5 A and provides a continuous torque at standstill of 28.0 Nm, a nominal output torque of 33.1 Nm, and an output power of 11.0 kW. The motor features liquid cooling and is equipped with digital servo feedback and an integrated absolute encoder, supporting position detection beyond 4096 revolutions. The device has a plain shaft with a shaft seal and does not incorporate a holding brake. The centering diameter measures 130 mm, and the flange size is 192 mm. Power is connected to the right via a standard power connector, and optimal operation occurs at roughly 251 V and 187 Hz. Temperature regulation is facilitated by natural convection, with optional forced cooling via an external blower. The unit is configured without a holding brake and utilizes winding code 058.
