Product Description:

Bosch Rexroth Indramat’s SE-C4.210.030-14.000 is a brushless synchronous servo motor in the SE Synchronous Servo Motors series. It is intended for closed-loop positioning and velocity control in automated assembly, packaging, and material-handling stations. The unit converts three-phase drive power into precisely regulated shaft motion, allowing mechanical axes to follow programmed profiles without external speed reducers.

At its rated operating point, the rotor reaches 3000 rpm, providing a speed reference for motion sequences. During short acceleration intervals, the electromagnetic system produces up to 57.4 Nm of torque, while a continuous standstill torque of 21 Nm limits thermal loading on the windings. The inverter may command up to 158 A of phase current, while holding conditions draw 23 A. Electrical behavior is shaped by a stator inductance of 6.2 mH and a phase resistance of 0.51 Ω, both of which influence current rise time and copper loss. The torque constant is 0.92 Nm/A, and the back-EMF coefficient is 102 V per 1000 rpm, giving the drive predictable voltage demands. Rotor inertia is 4.98 × 10⁻³ kg·m², so speed changes are responsive yet stable.

The mechanical interface uses a 142 mm square flange, and the solid shaft measures Ø24 × 50 mm without a keyway, so clamp or shrink-disc couplings must transmit torque. A holding brake rated at 18 Nm secures the axis when power is removed. The brake coil requires only 1.0 A from a 24 V ±10% supply to engage. This low brake current reduces thermal loading on the cabinet power supply during prolonged stops. The solid shaft provides a direct interface for couplings that can accommodate the motor’s peak torque without relying on keyed engagement.
