Product Description:

The SD-B6.960.015-00.100 is a rotary actuator built by Bosch Rexroth Indramat for the SD Magnet Motors series. As a permanent-magnet synchronous unit, it converts drive current into controlled rotary motion for positioning tasks in automated equipment, material handling, and packaging lines. The part functions as the mechanical energy source within a closed-loop servo axis, delivering constant torque and repeatable speed when commanded by a compatible digital drive. Its construction suits the performance range of mid-frame magnet motors that provide high torque at moderate base speed. It is intended for servo-controlled axes where frequent starts, stops, and speed changes must remain consistent during production.

At standstill, the motor can develop 96 Nm, which is the maximum holding or breakaway load the axis can resist without rotor movement. Once energized, it reaches a base velocity of 1500 rpm, aligning with gear ratios that favor force rather than extreme shaft speed. A square 142 mm flange provides the mounting interface and matches standard machine plates. Rotor excitation is supplied by Ferrite magnets, providing stable residual flux in typical operating conditions. Power is transmitted through a 24 × 50 mm cylindrical shaft, a cross section sized to carry the listed torque with minimal torsional deflection.

The mechanical coupling surfaces are machined as a keyway and featherkey set, simplifying synchronous engagement with couplings or pulleys and ensuring slip-free torque transfer over repeated cycles. For installations exposed to gear oil or lubricated spindle chambers, an oil-tight bearing at the drive end helps prevent fluid ingress that could dilute the grease pack or contaminate internal components. Classified as a brushless servo motor, the unit eliminates commutator wear and reduces maintenance needs. The shaft and sealing arrangement suit direct coupling to transmission components that require positive torque transfer and controlled lubrication separation. This arrangement supports reliable rotary operation in applications that require accurate servo response and protected drive-end sealing.
