The Bosch Rexroth synchronous servo motor, MPN R911281188 (MHD115C-058-PG0-BN), features a liquid-cooled, closed housing design, making it suitable for challenging industrial environments. It incorporates a digital servo feedback system with an integrated absolute encoder supporting position detection over more than 4096 revolutions. This model, with a size code of 115, a motor length C, and a flange size of 192 mm, delivers a continuous torque at standstill of 70.0 Nm and is rated for a power output of 7.7 kW. The rotor has a moment of inertia of 138 x 10⁻⁴ kg·m² and a peak current of 371 A. The plain shaft, equipped with a shaft seal, supports high radial loads, and the power connection is oriented to side B using an output connector. Operating optimally between -20°C and 80°C, the motor’s torque constant is 0.95 Nm/A and voltage constant is 86.4 V/1000min⁻¹ at 20°C. The shaft's protective drive sleeve should remain in place during storage.
