Product Description:

The SE-C4.210.030-10.101 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. The unit serves as the electromechanical actuator in drive systems where rapid acceleration, repeatable positioning, and high cycle throughput are required. Its design supports direct coupling to ball screws or gearboxes, allowing CNC machines, printing lines, and material-handling gantries to translate drive commands into controlled rotary motion with low maintenance demands.

The motor has a rated speed of 3000 rpm and delivers a continuous static torque of 21 Nm. Torque is proportional to phase current through a torque constant of 0.92 Nm/A. Dynamic events are handled by a peak current limit of 158 A, while continuous standstill operation draws 23 A. The electrical time constant is 11.9 ms, and the mechanical time constant is 3.1 ms, so torque builds and shaft velocity settle within milliseconds after a setpoint change. A phase inductance of 6.2 mH limits rapid current changes, and a copper resistance of 0.51 Ω helps limit steady-state losses.

Thermal modeling provides a time constant of 35 min, allowing the motor to accommodate extended overloads before reaching thermal equilibrium. The rotor inertia is 4.98 × 10⁻³ kg·m², balancing fast acceleration with stable motion. The back-EMF gradient is 102 V/1000 rpm, supporting accurate voltage-mode control and tachometric feedback. An oil-tight drive-end plate protects the bearing set when the motor is installed in lubricated machine compartments. The smooth shaft is supplied without a keyway or feather key, making it suitable for clamp couplings or shrink discs. For legacy drives, the built-in tachogenerator produces 2.7 V per 1000 rpm with an accuracy of ±5%, providing an additional feedback signal for closed-loop regulation.
