Product Description:

The SF-A3.0093.060-00.050 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. Designed for closed-loop positioning and velocity tasks, the unit employs electronic commutation to coordinate stator currents with rotor position. By integrating into multi-axis drive chains, it converts DC link energy into rotary motion for pick-and-place modules, conveyors, or tooling spindles where quick acceleration and precise repeatability are required.

At a rated speed of 6000 rpm, the rotor can deliver high cycle frequencies, reducing dwell times in rapid indexing stations. The drive system supplies a bus voltage of 670 V, giving the magnetic circuit sufficient headroom for peak electromotive forces. A torque constant of 0.67 Nm/A links commanded phase current to shaft torque, simplifying current loop tuning. Position feedback is generated by an absolute encoder capable of 8 million increments per revolution, so small angular displacements are detectable by the controller. Mechanical integration is aided by a flange diameter of 116 mm, matching common gearbox and machine frames. When the shaft is blocked, the motor can resist a static load with 9.1 Nm of locked-rotor torque, which is used when calculating holding requirements under power-on conditions.

During startup, the winding draws a locked-rotor current of 13.5 A, which is used for inverter peak-current and cable sizing. Feedback quality is supported by a position accuracy of ±20 angular seconds, minimizing contour error in coordinated-axis applications. The housing follows the IM B5 mounting pattern, allowing face mounting to a flat machine plate, while the plug-in power and signal connections shorten installation time. Two integrated NTC temperature sensors relay real-time thermal data to the drive, and the encoder retains multi-turn position data when power is removed, so homing cycles are unnecessary at restart.
