Product Description:

The SE-B2.040.030-00.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for closed-loop positioning and velocity control, the unit converts electrical drive commands into precise mechanical rotation for axes in packaging machines, pick-and-place gantries, or tool changers. Its housing contains permanent-magnet excitation and stator windings sized for medium-power applications, allowing the motor to serve as a compact actuator in industrial automation that requires dynamic response and repeatable torque delivery.

Under rated operating conditions, the motor reaches a nominal speed of 3000 rpm, enabling direct coupling to gearboxes that accept this shaft velocity. At standstill, it can develop 5.0 Nm of static torque, while short bursts up to 13.2 Nm are possible when operated with the Sm 10/20 drive profile. The torque constant is 1.14 Nm/A, so output remains proportional to phase current. Current capability peaks at 26 A, giving additional headroom for acceleration events beyond the continuous standstill current of 4.5 A. A stator winding inductance of 54 mH, together with a resistance of 6.4 Ω, shapes the electrical response that the controller must regulate. The keyed Ø14 × 30 mm shaft and matching feather key provide positive torque transmission to couplings or pulleys.

The rotor inertia is 0.75 × 10⁻³ kg·m², allowing rapid speed changes without excessive drive gain demands, and the assembly mass is 8.8 kg, which supports use on moving axes. From zero to rated speed, the motor needs a ramp-up interval of 21 ms, and it also has an electrical time constant of 8.1 ms with a thermal time constant of 21 minutes. During rotation, the back-electromotive force rises at 112 V/1000 rpm, which is important for the drive’s available voltage range and regeneration behavior. The motor operates without additional cooling hardware.
