The Bosch Rexroth R911281188 (MHD115C-058-PG0-BN) synchronous motor is a sturdy, closed design device ideally suited for arduous environments, often utilized in paper, printing, food, and packaging industries. Key features include a data memory-equipped encoder for easy startup, flange design as per DIN 42948 for ease of attachment, and temperature monitoring to prevent overload. The 7.7kW motor, with a size code of 115, has a broad speed range due to electronic commutation, and performs optimally between -20°C and 80°C. Its rotor has a moment of inertia of 138 x 10-4 and a peak current rating of 371A, while the heating system dissipates efficiently. Further, it supports high radial loads, has a torque constant of 0.95Nm/A, voltage constant of 86.4V/1000min-1 at 20°C, and comes with a one-year global warranty. It should be noted that its protective drive shaft sleeve should not be removed during storage.
