Product Description:

The SE-C4.210.030-10.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It converts drive current into precise rotary motion, allowing CNC axes, pick-and-place heads, and packaging machinery to follow tightly controlled speed and position profiles in industrial automation. Mechanical integration is based on a 142 mm square flange, while the housing measures 347 mm long and the assembled motor weighs 22.0 kg; these values assist with machine layout and support structure sizing.

This motor generates a continuous static torque of 21 Nm, and its rated shaft speed reaches 3000 rpm for applications that require rapid indexing. Dynamic moves are supported by a rotor inertia of 4.98 × 10⁻³ kg·m², which balances quick acceleration with load stability. During short-term overloads, the windings can accept up to 158 A, while the continuous current at standstill is limited to 23 A to keep copper temperatures within safe operating limits. A torque constant of 0.92 Nm/A relates drive current to mechanical output, simplifying control-loop tuning. The internal copper resistance is 0.51 Ω at 20 °C, allowing copper losses to be calculated during thermal analysis.

The motor has an electrical time constant of 11.9 ms, which indicates the rate of current rise, and a mechanical time constant of 3.1 ms, which indicates how quickly speed settles after a torque step. The IP67 enclosure provides full protection against dust and temporary water immersion, supporting installation in washdown areas without additional covers. Power is transmitted through a shaft measuring 24 mm in diameter and 50 mm long, making it compatible with keyed or clamping couplings. The laminated core and 6.2 mH of winding inductance reduce the effects of inverter switching edges. A voltage constant of 102 V/1000 rpm establishes the back electromotive force used when evaluating regenerative operation.
