R911295557
Produced by Bosch Rexroth Indramat, the R911295557 (MKD093C-058-GG0-AF) is a high-performance servo motor from the MKD series, operating at an optimum speed of 6000 RPM and weighing in at 23.5 kilograms. This model carries an IP 65 rating for its housing, indicating top-tier protection from dust and jets of water, all encased in a black, prime coat finish. This motor hinges its rated torque and current on its operating mode, presenting 23 Nm torque with 28.3 Amps in air-cooled mode, and 43.7 Nm torque with 53.8 Amps under liquid cooling. While a holding brake isn't part of the standard package, customers can order an additional 22 Nm brake if necessary. For optimum function, the R911295557 (MKD093C-058-GG0-AF) has a voltage constant of 82.7 Volts per 1000 RPM and a torque constant of 0.91 Nm/A at 20 degrees Celsius.
The R911295557 (MKD093C-058-GG0-AF) has the winding code 058, offering a motor winding resistance of 0.74 Ohms and inductance of 5.8 millihenry at 20 degrees Celsius. The motor, with resolver feedback and 4 pole pairs, presents its encoder output and power connection on side A. Its main motor shaft is plain but with a sealing ring included. Bosch suggests an operating temperature of below 40 degrees Celsius and a set-up height below 1000 meters to avoid motor derating, and emphasizes protection from corrosive substances and vibrations during storage and transport. Direct handling and operation of this motor should be left to trained personnel.
