Product Description:

The SD-B6.720.020-01.000 is a brushless servo motor manufactured by Bosch Rexroth Indramat and supplied within the SD Magnet Motors series. Designed for closed-loop motion systems, it converts commanded current from an electronic drive into precise shaft positioning and controlled continuous rotation. This unit is used as a direct mechanical actuator for feed axes, gantry drives, and automatic tooling stations where repeatable torque delivery and rapid reversals are required in industrial automation. Because the motor is brushless, electronic commutation replaces physical brushes, which reduces wear and supports fast dynamic response.

A square mounting interface of 142 mm on the front flange provides the concentric alignment needed for rigid coupling to gearboxes or machine frames. The rotor uses Ferrite permanent magnets, giving the motor stable magnetic performance for general industrial duty. When the winding is driven to its rated frequency, the shaft reaches a nominal speed of 2000 rpm, which suits packaging lines and material-handling stations that do not require extreme velocity. The cylindrical shaft is ground to Ø 24 x 50 mm, allowing standard clamping hubs to transmit torque without a keyed connection. At zero speed, the electromagnetic circuit can sustain 72 Nm, which helps support loads before motion begins.

Drive settings should be matched to the motor’s torque and speed characteristics so current demand and sustained operation stay within the intended operating range. The square flange and ground shaft help maintain accurate alignment when the motor is connected to a gearbox or directly to a machine axis. Brushless operation also supports repeatable reversals and steady rotation in automated equipment that runs through frequent start-and-stop cycles.
