Product Description:

The SD-B3.068.030.10.000 is a permanent-magnet servo unit produced by Bosch Rexroth Indramat within the SD Magnet Motors series. In automated assembly cells and packaging lines, it converts controlled drive current into precise rotational motion for positioning tables, pick-and-place heads, and light conveying stages. Its compact rotor and low-loss stator winding support repeatable velocity and torque response during frequent starts, stops, and direction changes. This operating profile suits mid-power machine tools and handling gantries that need accurate axis movement without a large motor envelope.

The motor has a flange diameter of 116 mm, allowing direct attachment to gearboxes or mounting plates that follow the IEC pattern. Its output shaft measures 19 x 40 mm, which provides a practical balance between torsional rigidity and compact installation space for medium-load couplings. Under continuous excitation, the motor reaches a nominal velocity of 3000 rpm, so the connected drive should provide current control that supports this speed through the intended duty cycle. At standstill, it can deliver 6.8 Nm of torque, which is useful for static holding and low-speed indexing tasks that require stable torque near zero speed.

The delivery state is identified as basic equipment, so the shaft is supplied without a keyway and no integral brake is fitted. The rotor incorporates Ferrite magnets, which maintain stable magnetic behavior across a wide operating temperature range while supporting dependable servo response. As a brushless servo motor, the unit must be paired with an external inverter that provides sinusoidal commutation and feedback processing. The housing, seals, and winding insulation follow the standard SD series outline, and no optional coatings or sensor modifications are included.
