Product Description:

The SF-A2.0026.060-10.000 is a servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. Designed for precision axis control in industrial automation, it converts electrical energy into tightly regulated rotary motion needed by packaging stations, pick-and-place modules, and light machine-tool feeds. Its mechanical frame, electrical feedback, and thermal design work together so the motor can be paired with Rexroth drive controllers for closed-loop velocity and position regulation.

At standstill the motor can exert 2.6 Nm of continuous holding torque while drawing a steady 3.4 A; this low current level limits heat buildup during prolonged dwell periods. The electromagnetic design yields a torque constant of 0.74 Nm/A, meaning each ampere of phase current produces roughly three-quarters of a newton-meter, which simplifies drive tuning. Once energized, the rotor reaches a rated speed of 6000 rpm, making the unit suitable for high-throughput indexing tasks. A laminated rotor with 3.8 × 10⁻⁴ kg·m² inertia balances quick acceleration against mechanical stability, and a single-turn absolute (STG) encoder supplies unambiguous position data to the controller immediately after power-up.

Installation requirements are addressed through an IM B5 flange mount that mates directly to gearheads or machine plates using the standard 100 mm square interface. Overall housing length is 208 mm, and the assembly weighs 6.2 kg, so it can be handled without lifting equipment in most cabinet builds. Thermal energy leaves the stator by radiation and natural convection, eliminating the need for forced-air or liquid cooling. Additional dimensional points include a 95 mm pilot diameter for centering accuracy and a 14 × 30 mm smooth shaft that supports clamp couplings without keyways. Two NTC sensors embedded in the winding report temperature to the drive for overload prevention.
