Product Description:

The SE-C4.210.030-00.015 is a permanent-magnet synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied under the SE Synchronous Servo Motors series. It works with a compatible drive controller to provide regulated torque and speed on automated axes. The motor supports positioning applications in packaging lines, machining centers, and material-handling systems that require accurate, responsive motion.

A square mounting interface measuring 142 mm follows IEC dimensional patterns and supports alignment with compatible machine surfaces. The rotor maintains a rated shaft speed of 3000 rpm during continuous operation. The motor provides a standstill torque of 21 Nm, while transient loads can draw a peak phase current of 158 A. The stator windings have an inductance of 6.2 mH, which influences current rise time and helps smooth the drive output. Standstill current is 23 A, and the winding resistance is 0.51 Ω. The output shaft measures 24 mm in diameter by 50 mm in length and uses an A8 × 7 × 40 feather key for positive engagement with gearboxes or couplings. An overall motor length of 347 mm supports installation where axial space is limited. The cable connection is located on side A of the flange, allowing wiring to be routed from a consistent housing position.

Short-term process loads can reach a peak torque of 57.4 Nm within the motor’s operating limits. The torque constant is 0.92 Nm/A, indicating the relationship between motor current and generated torque. Back electromotive force is represented by a voltage constant of 102 V/1000 rpm, providing the drive with an electrical characteristic used for speed regulation. The motor has a mass of 22.0 kg, including the integrated tachogenerator. Its rotor inertia is 4.98 × 10⁻³ kg·m², which affects the acceleration and deceleration response of the connected axis. A thermal time constant of 35 minutes describes how quickly the motor temperature approaches equilibrium as operating load changes.
