Product Description:

The SG-B2.050.038-13.010 is a brushless servo motor produced by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. As a synchronous actuator, it converts drive current into controlled rotary motion for positioning tables, pick-and-place heads, and spindle drives in automated machinery. The motor attains a nominal speed of 4300 rpm, enabling fast cycle times when paired with a compatible drive.

A static torque of 4.7 Nm is available at zero shaft speed, allowing the motor to support vertical loads without external gearing. During standstill, the windings draw 9.5 A, and the resulting thermal load is removed through heat radiation and natural convection. Samarium-cobalt magnets identified as SmCo provide high magnetic energy while tolerating elevated temperatures. The motor has an IP65 protection rating, which prevents dust ingress and protects against low-pressure water jets so the unit can be mounted outside a control cabinet. The smooth shaft measures 19 mm in diameter and 40 mm in length, providing a straightforward interface for clamp-style couplings. A metallic housing protects the internal components, while a resolver returns rotor position and spindle speed information to the drive. The frame uses the standard IM B5 mounting arrangement, although IM V1 and IM V3 orientations are also permitted.

Operation is permitted within an ambient temperature range of 0 to 40 °C, matching typical shop-floor conditions. A small integrated holding brake clamps the rotor when power is removed, preventing suspended axes from drifting. The mounting interface uses a 100 mm flange that provides secure face mounting and is machined to accuracy class R for consistent alignment. The windings use Class F insulation in accordance with VDE 0530, allowing hot-spot temperatures up to 155 °C without insulation degradation. Power and feedback lines connect through a mating plug sized for conductors with a cross-sectional area of 1.5 mm², providing a clear basis for cable selection.
