Product Description:

The SF-A3.0093.030-14.000 belongs to the SF Servo Motors series manufactured by Bosch Rexroth Indramat. It is a rotary servo unit intended for closed-loop positioning and velocity control in industrial automation lines, where precise torque delivery and environmental sealing are critical. The motor is suited for repeatable axis movement in equipment that must accelerate, stop, and hold position with consistent accuracy.

This motor reaches a nominal speed of 3000 rpm while delivering a standstill torque of 9.3 Nm under a standstill current of 6.4 A. A torque constant of 1.35 Nm/A links input current to output torque. The housing carries an IP67 ingress rating, so the stator windings remain protected during washdown cycles. A sinusoidal back-EMF profile minimizes torque ripple, and IM B5 flange mounting supports rigid coupling to gearboxes or machine frames. Mechanical power is transferred through an output shaft that measures Ø19 × 40 mm, while power, brake, and encoder connections use plug connectors for straightforward installation and service. Position data comes from a single-turn absolute encoder (STG), and feedback signals are routed to the drive through a dedicated plug.

For static holding or emergency stops, the integrated brake supplies 10.0 Nm of torque and is energized through a control line rated at 24 V DC ±10%. A rotor inertia of 15.8 ×10^-4 kg·m² balances dynamic response against load stability, allowing smooth acceleration without overshoot. Thermal supervision relies on 2 NTC sensors embedded in the stator, which feed real-time temperature data to the drive so that current derating can occur before winding limits are reached. This arrangement helps protect the motor during frequent starts and stops.
