The Bosch Rexroth R911315434 (MKD090B-047-GG2-KN) is a synchronous AC servo motor designed for industrial automation applications. This model features a plain shaft with a radial shaft sealing ring, resolver feedback for relative position detection, and a holding brake for securing the servo axis when de-energized. The unit operates at a frequency of 233 Hz with a 332-371 V connection to the drive controller via A1, A2, and A3 terminals. It delivers a rated power of 3.4 kW, a continuous standstill torque of 12.0 Nm, and operates at a rated speed of 3000 RPM. The cooling system employs natural convection, with an optional blower for high-load scenarios. The motor has a motor length B, 140 mm flange size, and is protected to IP65 standards, suitable for operating temperatures from 0°C to 40°C. Electrical connection is achieved through a connection box.
