Product Description:

The SD-B4.070.030-10.000 is a brushless servo motor created by Bosch Rexroth Indramat for the SD Magnet Motors series. It integrates with a digital drive for closed-loop velocity and position regulation, converting electrical commands into precise mechanical motion suitable for feed axes, pick-and-place heads, and other position-controlled assemblies in automated lines. Its brushless design supports responsive motion in applications that require frequent starts, stops, and direction changes during normal servo operation.

This motor attaches to machinery through a square mounting interface that measures 142 mm across the flange, providing predictable alignment with standard gearboxes and frames. Its rotor is energized by permanent magnets made of Ferrite, so no external field supply is required and demagnetization tolerance remains moderate. The rated operating velocity reaches 3000 rpm, a speed range that matches typical servo drives without excessive centrifugal stress. Power is delivered through a cylindrical shaft sized at Ø 24 × 50 mm, which provides torsional stiffness while helping maintain a compact output geometry. The configuration is supplied without a brake, which reduces rotational inertia in systems that do not need an electromechanical holding function. This layout is well suited to machinery that depends on the drive for active holding during controlled operation.

At standstill, the motor can resist load torque up to 7.0 Nm, allowing stable position control when commanded current is applied by the drive. Because the shaft is manufactured without a keyway, coupling systems must rely on clamping hubs, which eliminate stress risers and simplify balance at elevated speeds. The designation Basic equipment indicates a standard configuration for this motor. The smooth shaft form also supports uniform contact pressure in precision couplings, which helps maintain accurate torque transfer during repeated motion cycles.
