Product Description:

Bosch Rexroth Indramat manufactures the SG-B2.086.034-14.010 synchronous servo motor for the SG Synchronous Servo Motors series. As a brushless permanent-magnet unit, it provides closed-loop rotary actuation in packaging machines, gantries, and general motion axes that demand high repeatability. The motor converts drive current into controlled torque and speed, allowing precise positioning within automated production cells. Electronic commutation eliminates brush wear and allows the connected drive to regulate the rotor through repeated positioning and speed-control cycles.

The motor reaches a nominal speed of 3500 rpm, enabling fast cycle times when coupled to gear or belt transmissions. At standstill, it can deliver 8.2 Nm, allowing static loads to be held without shaft motion. This torque is obtained from a standstill current of 13 A, and the motor has a torque constant of 0.66 Nm/A. Dynamic behavior is influenced by a rotor inertia of 0.470 × 10⁻³ kg·m², which balances acceleration response against load stability. Flange accuracy grade R supports concentric mounting on precision gearboxes, while the 244 mm housing length permits installation in machinery with limited axial space. The motor’s electrical connection supports the brake power circuit, and its thermal design keeps winding temperatures within the permitted range during continuous operation.

A permanent-magnet holding brake supplies 15 Nm of holding torque to lock the shaft when power is removed. It draws 19 W from a 24 V DC control feed and adds 0.1 × 10⁻³ kg·m² of brake inertia to the rotor system. The smooth output shaft measures Ø19 × 40 mm, avoiding keyway stress points when used with a properly fitted friction coupling. The enclosure is rated IP65, preventing dust ingress and protecting internal components against water jets in washdown or machining areas. The motor has a total mass of 7.7 kg, which facilitates handling during installation while providing thermal mass for intermittent overload conditions.
