Product Description:

The SE-B2.030.060-14.028 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. It is intended for direct coupling to digital drive controllers, where it converts electrical input into controlled torque and speed for indexing tables, pick-and-place axes, and other automated motion systems. The compact housing and standardized mechanical interface help the motor fit into confined machine spaces without sacrificing closed-loop positioning accuracy. Its layout supports applications that need quick response, repeatable motion, and stable speed control during frequent start-and-stop cycles.

The motor reaches a nominal speed of 6000 rpm and can generate up to 8.0 Nm during short acceleration cycles. Drive electronics may command a peak phase current of 45 A, while only 7.5 A is required to hold a load at standstill. The motor has a static torque of 3.0 Nm, which supports holding performance when the shaft is not rotating. Its torque constant is 0.43 Nm/A, and the copper windings have an inductance of 14.0 mH. The winding resistance is 2.25 Ω, which affects current rise and heat generation during continuous operation. A mechanical time constant of 7.5 ms and a back-EMF slope of 45 V per 1000 rpm support responsive speed control and predictable electrical behavior.

Dynamic current response is set by an electrical time constant of 6.1 ms, which works with the winding inductance to smooth current changes. Rotor inertia is 0.60 × 10⁻³ kg·m², allowing fast acceleration while helping the axis remain stable during rapid reversals and short positioning moves. The mounting face uses a flange diameter of 95 j6 mm, and the output shaft measures 14 k5 mm in diameter with a length of 30 mm. Those shaft and flange tolerances provide a standardized coupling point for hubs, pulleys, and other drive components that require accurate alignment.
