The Bosch Rexroth MPN R911295991 (MHD095C-058-NG1-RN) is a synchronous servo motor intended for rapid-response automation tasks. It utilizes a brushless configuration with lifetime grease-lubricated bearings, and features high thermal conductivity from the stator to the motor housing, supporting effective overload operation. The unit supports a continuous standstill torque of 23.0 Nm, operates at nominal and maximum speeds of 4,000 rpm and 6,000 rpm respectively, and is equipped with a holding brake delivering 22.0 Nm torque. It uses digital servo feedback (HSF) for relative position detection. The motor is designed for mounting with a centering diameter of 130 mm, flange size of 140/150 mm, in a liquid-cooled housing, and includes a plain shaft with shaft sealing. Rated with an IP65 ingress protection, it maintains optimal performance in 0°C to 40°C ambient temperatures and up to 1000 meters above sea level. The power connection is supplied via a right-sided power connector.
