SF-A3.0068.030-00.018

SF-A3.0068.030-00.018, Bosch Rexroth Indramat, SF Servo Motors constitute a high-performance brushless drive solution optimized for precision motion control. The motor employs a permanently magnet-excited rotor with sinusoidal e.m.f. excitation and integrates an STG/MTG encoder for dependable position feedback. Its compact aluminum housing supports a DC link voltage of 670 V and features installation pockets for simplified mounting. The design omits a holding brake in favor of a low-inertia rotor profile that enhances dynamic response.

In operation, the unit delivers a locked-rotor current of 6.8 Nm at a rated speed of 3000 rpm, sustaining peak acceleration without torque ripple. It is built to Construction type IM B5 standards and enclosed to Protection rating IP 67, safeguarding the electronics against dust and moisture. Thermal management relies on Cooling type natural convection with optional surface ventilation attachments, keeping surface temperatures below 100 °C. The motor’s Encoder type single-turn absolute system maintains position accuracy, while its output shaft: feather key and key way conforms to DIN 6885 for reliable torque transmission.

The assembly weighs just Mass 9 kg and extends to a Maximum length 255 mm, with a Moment of inertia 11 x 10⁻⁴ kg·m² that minimizes energy loss during start-stop cycles. Acoustic performance is rated at Noise behavior 58 dB at 1 m, enabling use in noise-sensitive environments. Integrated electronic rating plates and dual NTC sensors provide continuous diagnostics, streamlining integration with Servodyn-D drives and ensuring long-term operational reliability.
