Product Description:

The SF-A2.0020.030-10.053 is a servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. It is intended for closed-loop motion tasks on assembly cells, gantries, and indexing tables where stable speed control and repeatable positioning are required. When paired with a compatible drive controller, the motor converts commanded current into controlled rotary motion for accurate axis response. Its design suits applications that need consistent torque delivery and dependable cycle-to-cycle repeatability without adding unnecessary mechanical complexity.

The motor reaches a rated speed of 3000 rpm, which suits continuous operation on many automated axes. Its intermediate circuit accepts 670 V from the drive, providing the electrical headroom needed for fast acceleration and controlled dynamic response. When the rotor is blocked, the winding draws 1.3 A and produces a locked-rotor torque of 2.0 Nm. A torque constant of 1.5 Nm/A shows the relationship between current and produced torque, which helps the drive respond predictably to load changes. Cooling is done by radiation and natural convection, so the motor does not require forced cooling hardware.

The motor uses a square flange that measures 100 mm, allowing direct installation on standard IM B5 mounting surfaces. Dynamic response is influenced by a rotor inertia of 3 × 10^-4 kg·m², which supports quick speed changes while keeping the axis manageable for closed-loop control. Thermal protection operates across a range of -5 to +155 °C, helping protect the insulation system during abnormal loading conditions. During operation, sound pressure remains below 58 dB(A), which supports use on machinery installed near regularly occupied work areas. Position feedback is supplied by an absolute value encoder, so position information is available after power-up without relying on a separate reference run.
