Product Description:

The SF-A2.0020.030-00.000 is a servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. With a housing length of 198 mm, it fits installations that need a compact motor for positioning and feed-drive tasks in packaging, assembly, and material-handling equipment. The motor converts controlled current from a matched inverter into precise rotary motion, which supports repeatable starts, stops, and speed changes during automated production. Its compact body helps reduce the space needed around the axis while still providing the motion control expected from a servo application.

Cooling is handled by natural convection, so the motor does not require external fans or liquid circuits. The motor is connected to a DC bus that can reach 670 V, enabling the drive to support a nominal speed of 3000 rpm. Its torque constant is 1.5 Nm/A, which means output torque rises in proportion to motor current at standstill. When the shaft is blocked, the motor can deliver up to 2.0 Nm while drawing 1.3 A, and the 14 mm × 30 mm shaft passes torque to couplings or gear stages. This arrangement supports accurate motion transfer in compact drive systems where stable low-speed response is important.

The feedback system uses a single-turn absolute encoder with a resolution of 8 million increments per revolution. Its guaranteed accuracy is within ±20 angular seconds, which gives the control loop precise position data for indexing and repeat motion. Rotor inertia is 3 × 10⁻⁴ kg·m², helping the axis respond quickly to changes in command speed and direction. Mechanical mounting is supported by a square flange measuring 100 mm across, and the motor has a mass of 5.5 kg. These values make the unit suitable for assemblies where accurate feedback, moderate inertia, and low added load are all important.
