Product Description:
The SE-C4.170.030-00.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It is intended for industrial automation tasks that require precise torque and speed control. The unit transforms regulated drive currents into repeatable rotary motion for indexing tables, pick-and-place heads, and similar positioning axes. A 24 mm diameter shaft with an A8 × 7 × 40 key transmits torque directly to couplings, while the overall body length of 315 mm allows installation in compact machine frames.
This model reaches a nominal speed of 3000 rpm, supporting continuous motion profiles used in high-cycle production equipment. During short load spikes, the servo can deliver a peak torque of 43.0 Nm. Rapid acceleration is supported by a peak phase current of 111 A, while continuous operation at zero speed requires a current of 19 A. The torque constant of 0.91 Nm/A allows the drive controller to calculate shaft torque from the commanded current. The rotor has an inertia of 4.08 × 10⁻³ kg·m², which supports responsive changes in speed. The available motor cable has a conductor cross-sectional area of 6.0 mm² to carry the required current while limiting conductor heating.
The motor has a mass of 19.0 kg and mounts to a 142 mm IEC flange, providing a stable interface with the machine frame. The mounting interface has a diameter of 142 mm for alignment with compatible equipment. Internally, a winding inductance of 9.3 mH smooths current transitions during changes in motor output. A phase resistance of 0.68 Ω limits steady electrical losses during continuous operation. The shaft extends 50 mm beyond the bearing face to provide sufficient engagement with a clutch, coupling, or gearbox. Its keyed design provides positive torque transfer and helps prevent the connected component from slipping on the shaft under load.
