Product Description:

The SF-A3.0093.030-10.050 servo motor is a compact rotary actuator from Bosch Rexroth Indramat in the SF Servo Motors series. As a permanent-magnet synchronous unit, it converts drive current from an electronic amplifier into precise torque and speed for positioning tables, gantries, or feed axes in automated machinery. Its construction supports closed-loop control, allowing tight motion profiles essential for repeatable industrial automation cycles. This operating principle also supports smooth low-speed motion and accurate settling after rapid changes in direction.

It delivers a nominal shaft velocity of 3000 rpm, generated with a torque constant of 1.35 Nm/A, so each ampere of phase current contributes predictable rotary force. During standstill, the windings can carry 6.4 A, enabling the motor to hold position until motion is commanded, while a locked-rotor torque of 8.1 Nm counters external loads at zero speed. Environmental sealing meets the IP67 code, so dust entry and temporary immersion do not affect operation, and the housing relies on natural convection because it is built without forced-air cooling. For braking, the integral holding circuit energizes at 24 VDC and isolates rotation with 0.66 A of coil current. The rotor inertia is 16 × 10⁻⁴ kg·m², which helps the axis balance responsive acceleration with stable motion under changing loads.

A flange diameter of 116 mm matches standard gearbox patterns, and the shaft measures 19 × 40 mm, providing adequate torsional rigidity for couplings or pulleys. When supply power is removed, the electromechanical brake clamps with 10.0 Nm of static torque to secure vertical or indexing axes until a controlled release signal is issued. This arrangement helps the motor fit compact machine layouts where direct mounting and reliable holding at standstill are both important. The combination of shaft support and brake action is useful in applications that must limit drift before the next commanded move begins.
