Product Description:

The SF-A3.0093.030-14.050 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. It is designed for high-precision positioning and velocity control in factory automation, where the motor supplies regulated torque to packaging stations, pick-and-place gantries, and feeder axes that rely on closed-loop drive control. The motor uses a permanent-magnet rotor and resolver feedback for accurate motion response. Its IM B5 flange arrangement supports direct coupling to gearboxes or machine frames without additional adapter plates. This mounting style also helps the motor fit compact axis assemblies where repeatable alignment is important.

The motor reaches an output speed of 3000 rpm, which suits many servo-driven axes and common transmission ratios. Its torque constant is 1.35 Nm/A, so each ampere supplied by the drive produces 1.35 newton-meters of shaft torque. The spring-applied brake provides 10.0 Nm of static holding torque, and the brake coil releases at 24 VDC for low-voltage actuation. During stall conditions, the stator can deliver a locked-rotor torque of 8.1 Nm, while the associated 6.0 A current helps keep thermal rise within acceptable limits. These electrical and braking values support controlled starts, stops, and holding at standstill.

The permissible axial thrust is 133 N, allowing the shaft to accept moderate preload from belt drives or screw-driven mechanisms without excessive bearing stress. Rotor inertia is 16 ×10⁻⁴ kg·m², which supports quick acceleration while helping the motor maintain stable speed during changing load conditions. Sound pressure does not exceed 58 dB(A), which helps the motor operate quietly in enclosed machinery areas. The assembly is engineered for a minimum operating life of 20,000 h, supporting long service intervals during continuous-duty operation. These values make the motor suitable for equipment that runs repetitive motion cycles over extended periods.
