Internal Product Review
The SG-B2.086.034-10.010 is a brushless servo motor with IP65 protection. Resolver feedback for rotor orientation and spindle speed, along with a 3500 rpm nominal speed, gives the motor excellent control quality in demanding motion systems. A static torque rating of 8.2 Nm stands out as a strong advantage for precise servo duty.

Product Description:
The SG-B2.086.034-10.010 is a synchronous drive module offered by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. It is designed for closed-loop axis duties in machine tools, packaging cells, and material-handling stations. The motor converts three-phase electrical power into precise rotary motion that can be regulated for speed and position by a matched drive controller. Its operating characteristics support controlled acceleration, repeatable positioning, and steady rotation in automated equipment.
At a nominal shaft speed of 3500 rpm, the motor delivers a static torque of 8.2 Nm, providing a balance of quick indexing and holding capability. To reach that torque, the windings draw a standstill current of 13 A, which is used when sizing the drive amplifier and power cabling. Permanent-magnet excitation is produced by SmCo material, which maintains its magnetic strength across wide temperature changes and contributes to the motor’s compact dimensions. An enclosure rating of IP65 seals the housing against dust and water jets, allowing the unit to be mounted outside an electrical cabinet on moving axes.
Thermal radiation and natural convection remove heat, allowing continuous operation within an ambient temperature range of 0 to 40 °C without external fans. The B5 flange face has a diameter of 100 mm and follows Accuracy R tolerances, supporting accurate alignment with attached equipment. The smooth shaft measures 19 mm in diameter and 40 mm in length, allowing direct connection to compatible precision gearheads. Class F insulation protects the stator windings from excessive temperature rise, while the resolver supplies rotor-position feedback to the drive controller. The metallic housing supports industrial durability and washdown cleaning, while the smooth shaft profile and absence of a holding brake reduce rotating inertia. IM V1 and IM V3 mounting orientations are permitted, providing flexibility when the motor must be installed vertically. A mating connector with a 1.5 mm² conductor cross section carries the required current without excessive voltage drop.
