Product Description:

The SF-A2.0041.060-00.000 is an AC servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. It serves as a rotary actuator that converts drive current into controlled torque and speed for automated gantries, packaging axes, and material-handling stations. Integrated DSF multi-turn absolute feedback communicates shaft position over multiple revolutions, permitting high-resolution closed-loop motion without homing after power loss. When paired with a compatible drive, it supports precise positioning sequences and synchronized line speeds in demanding industrial processes.

During continuous operation, the stator windings draw a standstill current of 24.1 A to produce 14.5 Nm of holding torque without overheating. At rated operation, the shaft can maintain a nominal speed of 3000 rpm, and short-term load surges are supplied through a 108.2 A peak current ceiling from the inverter. Each ampere contributes torque in proportion to the motor’s 0.60 Nm/A torque constant, which helps current-loop tuning. Electrical losses are limited by a 0.43 ohm phase resistance, while a 4.4 mH winding inductance shapes the drive’s pulse-width modulation filters. All power cabling terminates on side A, which supports straightforward cabinet routing.

Mechanical integration starts with a 130 mm centering diameter that aligns the flange, and a shaft machined with an 8 × 7 × 40 mm key transmits torque. A 22 Nm holding brake secures vertical loads when the drive is disabled, while motion peaks can reach a theoretical maximum of 45.1 Nm to overcome inertial starts. The rotor’s 29 × 10⁻⁴ kg·m² inertia balances quick acceleration against overshoot, and the motor’s 16.5 kg mass adds structural damping. Thermal behavior is characterized by a 50 min time constant, which allows extended duty cycles before heat saturation.
