Product Description:

The SE-B2.040.030-10.015 is a synchronous servo motor built by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. Intended for integration into compact motion modules, it converts three-phase drive power into controlled rotary movement for indexing tables, feed drives, and small gantry axes. The motor supports the closed-loop performance necessary for position, velocity, or torque regulation in industrial automation.

At a mass of 8.8 kg, the unit can be mounted on medium-duty frames without significantly disturbing load balance. Its nominal working speed is 3000 rpm, supporting direct correspondence between command frequency and mechanical output in 1:1 drive ratios. For short accelerations, the rotor produces up to 13.2 Nm, and the inverter may draw a peak phase current of 26 A to reach that value. Acceleration from rest to nominal speed occurs in 21 ms, which shortens cycle times in pick-and-place axes. During static holding, the control maintains 4.5 A of standstill current to hold the commanded position without overheating. This standstill capability supports applications that require steady torque while the shaft remains stationary.

The dynamic profile relies on a rotor inertia of 0.75 × 10⁻³ kg·m², so the drive can command frequent reversals without excessive overshoot. Continuous-duty torque at standstill reaches 5.0 Nm, providing capacity for vertical loads or holding without a brake. Electromechanical conversion uses a torque constant of 1.14 Nm/A and a back-EMF constant of 112 V/1000 rpm; these values support current-loop adjustment and indicate the regenerative voltage produced during deceleration. The stator has 54 mH of winding inductance and 6.4 Ω of resistance, forming an electrical time constant that filters ripple supplied by the inverter. The shaft has no keyway, so clamping or tapered hubs must be used to transmit torque. A mating connector is not included and must be selected separately for the intended cable and drive connection.
