Product Description:
The SD-B5.380.020-00.010 is a permanent-magnet rotary actuator from Bosch Rexroth Indramat and belongs to the SD Magnet Motors series. It is intended for closed-loop motion tasks in automated machinery, converting drive controller current into controlled torque for conveyors, pick-and-place axes, and indexing tables. By using a contact-free rotor construction, the motor supports reduced maintenance while sustaining high positional accuracy in continuous duty. Its direct-drive design also suits applications that need frequent starts, stops, and short indexing moves without the wear associated with brush contact systems. That makes it suitable for machinery that must hold position accurately between motion segments.
At zero speed, the rotor supplies 38 Nm of electromagnetic holding torque, allowing vertical or suspended loads to remain stationary without an external brake. Under rated electrical and thermal conditions, the shaft reaches a nominal velocity of 2000 rpm, which supports stable continuous operation. A square 116 mm mounting flange matches common gearbox and frame patterns, while the output journal measures ø 19x40 mm for direct coupling to pulleys or flexible couplings. Constant field excitation is provided by Ferrite magnets, giving stable magnetic flux over a broad temperature span and eliminating the need for field windings. This combination is useful in compact motion axes where secure holding and steady running speed are both required.
The output spindle is machined as a shaft with a keyway and feather key, so torque transfer relies on a positive mechanical lock instead of surface friction. Because the construction is that of a brushless servo motor, commutation is performed electronically, and the absence of brushes minimizes arcing. This arrangement supports repeatable positioning during frequent reversals and helps reduce service interruptions in high-duty production cells. Electronic commutation also allows the connected drive to regulate rotor motion smoothly during low-speed holding and higher-speed travel.
