Product Description:

The SD-B3.050.030-10.000 is a permanent-magnet servo motor produced by Bosch Rexroth Indramat within the SD Magnet Motors series. Designed as an electromechanical drive element, the unit converts drive current from a matching servo amplifier into controlled rotary motion for positioning tables, pick-and-place arms, and other automated axes. Its brushless construction eliminates commutator wear, making the motor suitable for continuous duty cycles in industrial automation cells that demand accurate velocity and torque regulation. This layout supports repeatable response in packaging, transfer, and general handling equipment.

The square flange measures 116 mm, providing a standard mounting interface for gearboxes or direct-drive couplings. A rotor built with Ferrite magnets produces the magnetic field needed for operation. The rated operating point is a nominal speed of 3000 rpm; drive controllers should match this value to keep synchronous operation under load. This speed suits many servo axes that require a broad operating range. Power is transferred through a shaft sized at ø 19x40 mm, which accommodates common clamping hubs without additional machining. At standstill, the motor can sustain 5.0 Nm of torque, enabling static holding or low-speed indexing without overheating.

As a Brushless servo motor, the unit relies on encoder feedback and electronic commutation, so there are no brushes to replace during preventive maintenance. The standard build is supplied without a brake, which means axis locking must be handled by the drive or an external mechanical latch when power is removed. It is also delivered without a keyway; couplings that use friction locking or shrink disks can therefore be mounted directly on the smooth shaft surface. This shaft arrangement keeps the output interface simple for direct coupling.
