Product Description:
The SF-A3.0042.060-10.050 servo motor is manufactured by Bosch Rexroth Indramat and belongs to the SF Servo Motors series. As a brushless rotary actuator, it converts electrical energy from the drive into controlled torque and speed for positioning axes, pick-and-place heads, or conveyor stations in industrial automation. Its permanent-magnet rotor, integrated encoder, and compact IM B5 flange construction allow direct mounting to gear stages or machinery frames while delivering high dynamic response. This layout supports compact machine designs and short power transmission paths.
During operation, the motor is supplied from a DC bus of 670 V, giving the internal inverter a wide voltage margin for rapid torque buildup. Under rated conditions, the shaft reaches 6000 rpm, a speed that supports fast cycle times in packaging or electronic assembly lines. Each ampere delivered to the stator windings produces 0.70 Nm/A of torque, so current reference signals translate proportionally into mechanical output. Dynamic reversals are aided by the low rotor inertia of 7 × 10-4 kg·m², minimizing overshoot in tight position loops. For startup scenarios where the shaft is locked, the drive may command 6.0 Arms of current. That combination helps the motor respond quickly to command changes in high-speed motion profiles.
Mechanical loading is accommodated by an admissible axial thrust of 133 N, protecting the bearings when belt tension or gear preload is present. Emergency stops can be handled electrically because the windings can absorb 261 Ws through plug braking while dissipating the energy through a 5.6 Ω resistor in the drive circuitry. Acoustic emission is limited to 58 dB(A), supporting installation near operator workstations. Additional features include encoder feedback with ±20 arcsec accuracy and 8 million counts per revolution. The feedback system supports stable closed-loop control during rapid acceleration and deceleration, and the motor has a shock tolerance of 6 g for transport vibrations with a noise-optimized IM B5 housing that aligns the flange face directly to the machine frame.
