R911279291
The R911279291 (MHD112C-024-NP3-AN) is a synchronous motor engineered by Bosch Rexroth Indramat. The motor's speed is synchronized to the frequency of its input current, which is supplied by a servo drive controller. It features a digital servo feedback that facilitates communication with the attached drive controller. The motor also incorporates an inbuilt holding brake with a holding torque of 70 Nm, released when a 24 Volts DC signal is presented. This brake uses 1.29 Amps and its connection and disconnection times are approximately 53 and 97 milliseconds respectively.
The motor R911279291 (MHD112C-024-NP3-AN) includes a main shaft with a key and seal, preventing dust, moisture entry and oil leaks. The motor maintains an IP65 protection rating due to the seal, sealed power, feedback connectors, and a completely sealed housing. The rated speed is 2500 RPM for the 60K overtemperature condition with natural convection. Its rated torque is 16.6 Nm, while the rated current and power output are presented as 8.2 Amps and 5.2 kilowatts respectively. The rated voltage and frequency are 372 Volts and 167 Hertz respectively. The absolute motor torque and current are 148 Nm and 120 Amps while its weight is 45 kilograms.
