SG-A3.055.049-13.010
SG Synchronous Servo Motors
SG-A3.055.049-13.010, Bosch Rexroth Indramat, SG Synchronous Servo Motors. This series motor features a compact IM B5 construction and IP 65 protection, allowing operation in harsh industrial environments. With a swift 0.46 ms time constant, it responds instantly to control signals, and its brushless resolver provides precise rotor angle feedback. The design standard emphasizes a small footprint without compromising torque density or reliability.
Designed for high-performance automation, the motor delivers a Torque At Standstill of 5.8 Nm and a continuous Holding Torque of 15 Nm, energized by a 24 V ± 10% Holding Brake Voltage. It achieves a Nominal Speed of 4800 rpm within a frame defined by a Flange Size of 140 mm and a Length Without Brake of 170 mm. The Shaft Diameter of Ø 24 × 50 mm supports direct coupling, while a low Moment Of Inertia of 0.93 kg·cm² enables rapid acceleration and deceleration. Thermal resilience is ensured through Thermal radiation and natural convection cooling, and the motor withstands factory vibrations up to Vibration Severity Grade Grade 'N.
Installation is simplified by standardized mounting dimensions and a lightweight design weighing 7.7 kg without brake or 9.0 kg with brake, facilitating integration into compact machine frames. Dependable IP 65 sealing and durable bearing assemblies guarantee long-term reliability in washdown or dusty conditions. The high torque density, rapid dynamic response, and built-in holding brake make this motor ideal for pick-and-place systems, high-speed spindles, and precision indexing tables in industrial automation.
