SG-B3.100.029-03.000

The Bosch Rexroth Indramat SG-B3.100.029-03.000 from the SG Synchronous Servo Motors series combines robust construction and precise performance in a single IP65-rated package. This motor delivers a nominal torque of 11.2 Nm at standstill and accelerates smoothly up to a speed of 3500 rpm, making it ideal for demanding industrial automation tasks. Its keyway and featherkey shaft ensures secure coupling with driven components, while the None brake design reduces maintenance requirements. Engineered for long service life, this servo motor is a reliable solution for packaging machines, robotic axes, and conveyor systems.

Advanced electrical characteristics underpin the SG-B3.100.029-03.000’s dynamic response and torque generation. The motor features a torque constant of 0.73 Nm/A (measured at 40 °C with 100 K thermal rise), providing predictable torque output per ampere of current. At standstill, the standstill current of 15.6 A yields the full rated torque without compromise. A thermal rise of 100 K is accommodated by its rugged housing, and the electric time constant of 0.80 kgm²×10⁻³ reflects its rapid load-change adaptation. Protection to IP65 standards guards against dust and water ingress in harsh industrial environments.

Mechanical integration is simplified by standard mounting dimensions and a compact footprint. The motor’s 140 mm flange matches common installation patterns, while the shaft dimensions of Ø22×50 mm offer precise alignment and torque transmission. With a housing length of 195 mm (excluding optional brake components) and a mass of 9.9 kg, the SG-B3.100.029-03.000 balances rigidity with manageable weight. Its optimized thermal management and vibration-resistant design ensure stable torque output during continuous operation, making it an essential component for high-speed spindles, indexers, and multi-axis servo systems.
