Product Description:
The SF-A3.0093.030-04.050 is a brushless servo motor built by Bosch Rexroth Indramat within the SF Servo Motors series. This rotary unit converts drive current into precise mechanical motion for indexing tables, pick-and-place axes, and other closed-loop automation tasks. By combining permanent-magnet excitation with an integrated holding brake, the motor supplies repeatable torque and speed references to machine controllers while fitting the dimensional constraints common to modular servo modules.
During continuous operation, the motor reaches a rated speed of 3000 rpm when used with a matching drive. The electromagnetic design yields a torque constant of 1.35 Nm/A, so each ampere delivered by the amplifier produces proportional torque for fine velocity regulation. Dynamic response is assisted by the low rotor moment of inertia of 0.0016 kg·m², limiting acceleration lag in short-stroke cycles. The mounting face uses a square flange measuring 116 mm, and a center hole machined to DIN 332-DS M6 helps align the housing on the machine frame. Power is transferred through a keyed output shaft that is 19 mm in diameter and 40 mm long, guided by a keyway with an A6×6×32 feather key. The enclosure carries an IP67 rating for washdown installation, and the 326 mm overall body length keeps the motor compact.
The integrated holding brake assists vertical or reversing loads, and it provides a static torque of 10 Nm. It engages when a control line supplies 0.66 A at 24 VDC, locking the rotor without external clamps and preventing drift when power is removed or during emergency stops. At 11.6 kg, the motor has enough mass to help damp vibration without becoming overly bulky. An integral shaft seal preserves lubrication and keeps contaminants out, supporting long-term service in fluid-exposed or particulate environments.
