Product Description:

The SG-B2.086.034-00.000 is a brushless servo motor built by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. As a closed-loop actuator, it converts drive current into controlled shaft rotation for positioning tasks in machine tools, handling axes, and packaging equipment. A resolver mounted on the rotor supplies speed and angular position feedback so the connected drive can correct deviations in real time. This feedback arrangement supports accurate motion under changing loads and during repetitive operating cycles.

The motor reaches a nominal speed of 3500 rpm, allowing fast cycle execution while remaining within its magnetic and thermal limits. A static torque of 8.2 Nm is available at zero speed for holding or low-speed indexing, and this output requires a standstill winding current of 13 A. The rotor magnets are made of SmCo, providing high magnetic flux density with minimal risk of demagnetization at elevated temperatures. The mechanical interface follows an IM B5 layout with a circular front face and a flange diameter of 100 mm, allowing alignment with compatible gearboxes and rigid couplings. Heat produced in the windings is removed through thermal radiation and natural convection, eliminating the need for forced-air or liquid cooling.

An enclosure rating of IP65 seals the interior against dust and low-pressure water jets, so the unit can be mounted close to process zones without an additional housing. Continuous operation is permitted from 0 to 40 °C, and Class F insulation allows the windings to reach 155 °C without losing dielectric strength. The shaft measures 19 mm × 40 mm and has a DIN 6885 keyway for transmitting torque directly to pulleys or couplings. Because the motor is supplied without a holding brake, power-off load retention must be provided by an external brake or clamp. Grade N vibration and flange accuracy support repeatable alignment in precision assemblies.
