Product Description:
The SD-B3 068 030-00 000 is a brushless servo motor produced by Bosch Rexroth Indramat in the SD Magnet Motors series. Intended for servo axes in automated packaging, pick-and-place, and material-handling lines, it converts controlled current into precisely regulated shaft rotation. Integrated rotor position feedback allows the connected drive to synchronize torque delivery with machine cycle demands, providing repeatable performance in both continuous and start-stop motion profiles. This arrangement supports stable acceleration and deceleration when the motor is used with a compatible servo amplifier.
The housing presents a mounting flange of 116 mm, giving the motor a standardized interface that aligns with common machine frames. A shaft with keyway and feather key transmits torque without slip, and its diameter and length are Ø 19×40 mm, so compatible couplings can be selected directly. Magnetic excitation is supplied by Ferrite poles, which provide stable magnetic flux during operation. Power conductors terminate on connectors for 1.5 mm² wiring, and that cross-section keeps copper losses low while remaining easy to crimp. Position data reach the drive through a dedicated cable that carries 10 × 0.14 mm² signal pairs plus 4 × 0.5 mm² power cores, and the encoder supply is ±15 V DC. Differential A, B, C and index 1, 2, 3 signals support commutation control so phase currents stay aligned with the magnetic field. A thermistor embedded in the winding reports internal temperature to the controller during operation.
Signal integrity on the feedback harness is protected by Screened cabling, which helps keep switching noise out of the encoder channels. For speed monitoring, the motor supplies a brushless DC tacho that generates 2.7 V/1000 rpm, and its linearity remains within ±5%. An internal cutout trips at 140 °C, forcing the drive to disengage before insulation limits are exceeded. Shielding on the feedback wiring also helps preserve clean signal transmission when the motor operates near power cables and inverter switching activity.
