Product Description:

The SD-B4.070.030-15.000 is a servo unit produced by Bosch Rexroth Indramat in the SD Magnet Motors series. Designed for closed-loop motion in industrial automation, it works with a digital drive controller to generate precise angular displacement and controlled speed for indexing tables, pick-and-place heads, or light machining spindles in packaging, assembly, and material-handling equipment. This operating role suits machinery that depends on quick direction changes, stable low-speed motion, and feedback-based correction during acceleration, deceleration, and dwell periods when the load can shift within the cycle over extended production runs.

A square mounting interface uses a 142 mm flange side length, allowing direct attachment to standard ISO gearboxes and brackets without adapter plates and helping the motor seat accurately on machine faces. Rotor excitation is provided by Ferrite magnets, which offer moderate energy density, stable flux characteristics, and predictable magnetic behavior under normal industrial operating conditions. The motor reaches a nominal shaft speed of 3000 rpm, which suits many inverter output frequencies and gives the connected axis a useful operating range for positioning and steady speed control across start-stop sequences and continuous running states.

At standstill, the shaft can deliver 7.0 Nm, giving the axis useful holding capability before commanded movement begins and supporting applications that need firm response from zero speed. Power is transmitted through a cylindrical shaft measuring 24 × 50 mm, which provides a practical balance of bending strength and torsional stiffness for couplings or timing pulleys. Because the motor is a brushless servo motor, it uses electronic commutation instead of carbon brushes, which reduces wear items and supports repeated duty cycles. This arrangement suits mechanisms that rely on direct coupling or belt-driven transmission while maintaining consistent rotary output in compact automation stations.
