Product Description:

The SE-B3.095.060-10.037 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. In automated machinery, it converts regulated drive current into precise rotary motion so drive controllers can position tooling, conveyor sections, or indexing tables with closed-loop accuracy. The unit is supplied as a bare-shaft model intended for direct coupling to gearboxes or pulleys in industrial automation cells. This layout suits installations where a compact servo motor must deliver accurate motion without adding a keyed shaft interface.

During operation, the rotor can spin up to 6000 rpm, which gives the motor a high nominal operating speed when the stator windings are driven at rated frequency. The motor can deliver a maximum short-term torque of 26.0 Nm for rapid acceleration, while its continuous static torque capability is 9.5 Nm at standstill. To reach these values, the drive may command up to 92 A of peak current, while normal holding conditions require only 15 A. Torque production is linked to the torque constant of 0.64 Nm/A, so each ampere of phase current produces that amount of torque. The low rotor inertia of 2.07 × 10⁻³ kg·m² supports quick speed changes, and the 0.66 Ω winding resistance together with the 8.4 mH inductance affect current rise and drive response.

The motor body weighs 14.5 kg, and its overall length stays within 320 mm, which helps it fit into compact drive modules with limited axial space. A shaft diameter of Ø19 × 40 mm is provided without a keyway, so torque transfer requires a clamp or shrink-fit coupling rather than a keyed hub. The back-EMF gradient is 64 V/1000 rpm, and the servo drive uses that value to estimate voltage demand as motor speed increases. The shaft arrangement is suited to applications that use friction-lock couplings and need accurate concentricity between the motor and the driven load.
