Product Description:

The SF-A5.0700.030-14.000 is a servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. It is intended for closed-loop positioning and speed-control duties in industrial automation, where commanded current is converted into controlled shaft torque for gantries, packaging axes, and material-handling modules. The motor combines torque production, position feedback, and holding capability in one assembly, which helps simplify axis layouts where compact integration and repeatable motion are required.

At its rated operating point, the motor turns at 3000 rpm, giving it a speed range that suits fast indexing and general servo motion. Its torque constant is 1.53 Nm/A, allowing the drive to relate phase current to produced torque in a direct and predictable way during acceleration and steady running. A flange diameter of 190 mm sets the mounting footprint, while the housing length and rotor inertia influence how the motor fits the machine and responds to changes in commanded speed. Position feedback comes from a single-turn STG encoder with 8 million increments per revolution and 20 arc-seconds of precision, supporting accurate closed-loop motion and stable velocity regulation.

The spring-applied holding brake can maintain continuous axial load without power and provides 56 Nm of holding torque when the axis must remain fixed at standstill. It draws 1.33 A to release, stores 30 × 10⁻⁴ kg·m² of kinetic energy, and disengages in 97 ms so commanded motion can begin with a short brake-release delay. During startup, the motor can produce a locked-rotor torque of 69 Nm with a corresponding locked-rotor current of 45 A, which indicates strong low-speed torque availability. The motor has an overall mass of 55.2 kg, and its steel shaft measures 32 × 58 mm for direct coupling to compatible gearboxes or driven machine elements.
