Product Description:

The SE-B2.020.030-00.028 synchronous servo motor is produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. This compact unit is intended for high-accuracy rotary positioning and speed regulation in automated machinery such as pick-and-place axes, small gantries, and packaging stations. By converting electrical energy from a matched drive into controlled mechanical torque, the motor provides repeatable motion profiles required for modern industrial automation lines. It is well suited for machine sections that require short moves, repeatable starts and stops, and stable speed control during frequent duty cycles.

At a nominal speed of 3000 rpm, the rotor supports continuous operation, and the motor has a standstill current of 2.7 A. A centering diameter of 95 mm and a square flange measuring 100 mm simplify alignment to gearboxes or frames, while the overall mass of 6.5 kg helps keep moving inertia low during acceleration cycles. The housing length is limited to 230 mm, so the motor fits into tight enclosures, and its connector area accepts 1.5 mm² conductors for both power and feedback wiring. Shock resistance up to 6 g helps protect internal magnets and windings during transport or abrupt machine stops, and reliable function is maintained at ambient temperatures up to 40 °C.

The mechanical output shaft is 14 mm in diameter and 30 mm long, and the keyway uses an A5 × 5 × 25 feather key for positive torque transfer. A maximum axial load of 154 N and a permissible radial force of 133 N at 70 mm from the flange support couplings, pulleys, or belt wheels without premature bearing wear. This shaft arrangement supports keyed hubs and similar drive components used in compact automation assemblies. The keyed connection helps prevent slip under changing load conditions while keeping the mechanical interface straightforward.
