Product Description:

The SE-B2.030.060-00.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It is intended for closed-loop positioning and velocity control on automated machine axes, where its compact flange and integrated feedback allow the drive controller to regulate rotor angle without mechanical backlash. In packaging cells, pick-and-place gantries, or light machining spindles, the motor converts drive current into controlled rotary motion that can be repeated over long duty cycles. Its compact format also suits equipment where accurate motion and limited installation space are both important.

The rotor can reach a nominal speed of 6000 rpm, enabling fast indexing or high surface speeds, while its static torque capability is 3.0 Nm for holding or low-speed duties. A torque constant of 0.42 Nm/A links developed torque to phase current, so 1 A produces nearly half a newton-meter. Peak acceleration current rises to 45 A, yet standby conditions require only 7.5 A at M0. The stator has a resistance of 2.25 Ω per phase and a winding inductance of 14.0 mH, which shapes the current-loop bandwidth required from the drive. The back EMF at rated speed is 45 V per 1000 rpm, and the shaft from the 100 mm square flange measures Ø14 × 30 mm for coupling to gears or pulleys.

Dynamic response depends on an electrical time constant of 6.1 ms and a mechanical time constant of 7.5 ms; these values show how quickly motor current and speed settle after a command step. Thermal equilibrium uses a 19 min heating time constant, indicating safe overload margins during short bursts. The rotor and encoder contribute to an inertia of 0.60 × 10⁻³ kg·m², while overall mass is 7.6 kg, which keeps the unit light enough for mounting on moving robot axes. Coolant air stabilizes the 40 °C reference temperature so the winding resistance and inductance remain consistent.
