Product Description:

The SE-B2.020.030-00.034 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Intended for tight velocity and position control in automated machinery, the motor accepts three-phase excitation from a drive controller and translates it into precise shaft rotation for pick-and-place, feeder, and auxiliary axes. It uses permanent-magnet excitation and encoder feedback compatible with Indramat drive amplifiers.

At its nominal operating point, the rotor turns at 3000 rpm, providing a static torque of 2.9 Nm while drawing a standstill current of 2.7 A. When short overloads occur, the winding can deliver a maximum torque of 6.9 Nm that corresponds to a peak phase current of 16 A, supporting fast indexing moves. Torque production is linked to the electromagnetic design; each ampere produces 1.10 Nm/A, and the field collapses with an electrical time constant of 5.0 ms. Mechanical response is equally fast: the 0.44 ×10⁻³ kg·m² rotor reaches speed in a mechanical time constant of 4.8 ms, and a full-scale velocity step is completed within the 24 ms ramp-up window. These values let the axis follow demanding command profiles without overshoot or lag.

System integration focuses on electrical matching and thermal endurance. A back EMF of 114 V/1000 rpm indicates the voltage range the drive must supply, while the stator’s inductance of 76 mH and a winding resistance of 14.7 Ω shape current loops and limit ripple. Heat generated under cyclic duty is released slowly; the motor reaches thermal equilibrium after 17 min, allowing sustained intermittent peaks before derating is required. This suits applications with repeated starts, short moves, and brief dwell periods. Mechanical coupling uses a shaft measuring Ø14 × 30 mm with a keyway and feather key, so torque is transferred positively to pulleys or couplings without slippage. The keyed shaft format is common in compact motion assemblies that need secure mechanical engagement.
