Product Description:

The SF-A4.0230.060-10.015 servo motor is built by Bosch Rexroth Indramat and belongs to the SF Servo Motors series. It is designed to pair with Rexroth digital drive controllers, transforming regulated DC link energy into controlled rotation for pick-and-place, feeder, and spindle axes. By combining a permanent-magnet rotor with tight internal feedback, the unit provides precise velocity and position control required in automated assembly lines and packaging machines.

The motor reaches its rated speed of 6000 rpm, which is the rated limit for continuous operation. To support this speed, the connected drive supplies a DC link voltage of 670 V, so insulation and wiring must be selected for that potential. The electromagnetic design has a torque constant of 0.88 Nm/A, which corresponds to about 1 Nm of torque for every 1.14 A of phase current. Rotor position is tracked by an absolute encoder that delivers 8 million increments per revolution, giving the controller fine resolution during positioning. During startup with a blocked shaft, the stator can draw 25 A until motion begins, so the stage must tolerate that surge. Mechanically, the housing follows the IM B5 construction style, allowing flange mounting to gearboxes or frames without brackets. Electronic commutation eliminates brush wear, and two NTC sensors embedded in the windings supply temperature data for thermal shutdown.

When the rotor is prevented from turning, it can resist a peak of 22 Nm, making the motor suitable for indexing stops that demand high holding capacity. In operation, shocks up to 6 g are tolerated, so it can be installed on mobile carriages or high-speed gantries without reinforcement. Power reaches the windings through a cable set of 4 x 6.0 mm². The mating plug accepts size 1.25 contacts that fit standard industrial drive connectors.
