The Bosch Rexroth synchronous servo motor R911288381 (MHD093B-058-NP0-AA) is designed for precision motion control applications. Operating at 200–330 V AC and 167–267 Hz, it supports continuous currents from 4.9–13.6 A, generating continuous torque between 5.4–15 Nm and reaching peak speeds up to 4000 RPM. It has a motor length of "B", a centering diameter of 130 mm, and a flange size of 140/150 mm. The shaft features a keyway and seal, with power connection to side A via an output connector. Sensing is achieved using a digital servo feedback encoder (HSF) with relative position detection. The unit is specified without a holding brake, has natural convection housing cooling, supports all installation orientations, achieves rated power outputs of 1.7–4.1 kW (natural) and 7.6 kW (surface cooled), and is IP65 rated for environmental protection.
