Product Description:

The SD-B3.050.030 05.000 belongs to the SD Magnet Motors series manufactured by Bosch Rexroth Indramat. It is a brushless servo motor intended for closed-loop positioning and velocity tasks within automated machinery. In motion axes that require repeatable torque delivery and stable speed, this motor converts drive current to mechanical rotation without brush wear. Because torque is produced electronically, the motor can respond precisely to command changes from a compatible servo drive. This makes it suitable for transfer units, feed axes, and compact machine stations with repeated motion cycles.

The motor bolts to a machine panel through a flange that measures 116 mm, so the mounting surface must match this square pattern. Its rotor uses Ferrite permanent magnets, which provide the magnetic field for torque production. When energized by the associated drive, the shaft reaches a nominal speed of 3000 rpm, enabling direct coupling to gear stages or belt transmissions that operate at moderate rotational rates. This speed helps the motor fit direct-drive or reduced-ratio arrangements without requiring unusually large pulleys. At standstill, the motor produces 5.0 Nm of torque. Mechanical linkage is provided by a shaft measuring 19 mm × 40 mm, which gives a 19 mm diameter and 40 mm of usable length for couplings, pulleys, or similar drive elements. The flange and shaft dimensions should be considered together when selecting couplings and machine-side supports.

Commutation is handled by electronic feedback rather than physical brushes. That arrangement supports smooth response during positioning and speed control while reducing wear at the commutation point. With feedback-based commutation, current can be synchronized to rotor position across the operating range. The absence of brushes also eliminates brush replacement as a routine service item. The motor follows the line's standard insulation and enclosure design for regular industrial use.
