Product Description:

The SG-B1.006.072-13.010 is a brushless servo motor manufactured by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. Designed as a high-speed, low-inertia actuator, it provides direct rotary power to indexing tables, miniature spindle heads, and pick-and-place modules used throughout automated assembly lines. When integrated with Rexroth digital drives, the unit delivers closed-loop torque and velocity control without requiring mechanical transmissions. This arrangement allows compact machine layouts and maintains consistent positional accuracy over extended production shifts.

A nominal speed of 8800 rpm allows the motor to achieve high surface velocities without external gearing, while the rotor’s SmCo magnets maintain magnetic strength at elevated temperatures and support low-inertia operation. The enclosure carries an IP65 rating that protects the motor against dust and splashing fluids during washdowns. Mounting follows the IM B5 face arrangement, and the 70 mm front flange is machined to Accuracy R to maintain coaxial alignment with precision tooling. Heat produced in the windings is dissipated through thermal radiation and natural convection, so no fan or liquid-cooling circuit is required. Class F insulation tolerates hot spots up to 155 °C, and the all-metal housing adds stiffness against vibration. These thermal features allow the motor to operate without the added space and maintenance requirements of auxiliary cooling equipment.

The motor operates reliably in ambient temperatures from 0 to 40 °C, making it suitable for most sealed cabinets and open machine frames. A rear-mounted resolver provides continuous rotor position feedback for high-gain current control loops. For vertical or indexing axes, a small integrated holding brake secures the shaft whenever power is removed. Power and feedback leads connect through a plug designed for 1.5 mm² conductors, reducing wiring bulk in confined spaces. A smooth shaft measuring 11 mm in diameter and 23 mm in length simplifies connection to collets, timing pulleys, or precision clamping hubs. The shaft dimensions also support compact coupling arrangements where available axial space is limited.
