Product Description:
The SE-B2.020.030-04.015 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It serves as a compact rotary actuator that provides controllable torque and speed to automated pick-and-place modules, small positioning tables, and indexing conveyors. The unit follows the IM B5 construction type, so its face flange aligns with the machine frame while the shaft extends outward for coupling. Integrated feedback provisions, energized through a ±15 V DC sensor supply, allow the connected drive to read actual speed and position without external transducers.
The motor can provide a holding torque of 2.0 Nm and reach a nominal operating speed of 3000 rpm. The rolling-element bearings have a service life of 20,000 h, providing long intervals between overhauls during continuous operation. The keyed output spindle measures 14 mm in diameter and 30 mm in length, allowing it to fit standard couplings. A face flange measuring 100 mm pairs with a centering diameter of 95 mm and an M5 centering hole to position the motor concentrically in servo gearboxes. Cable lugs sized for a 1.5 mm² motor connection area accommodate the phase conductors required at this power level.
The electromagnetic brake is powered by 24 V DC, providing a fail-safe holding function when supply power is removed. A built-in tachometer generator produces 2.7 V/1000 rpm, providing an analog speed signal for legacy regulators. The housing tolerates mechanical shocks up to 6 g during transport or emergency stops. Airborne noise does not exceed 58 dB(A) at the rated speed, helping facilities maintain acceptable workplace sound levels. The brake can secure a stationary axis when drive torque is unavailable, while the analog speed signal supports compatible control hardware without requiring an additional speed sensor.
