8LSA46.DB030S100-3 by B & R Automation

The 8LSA46.DB030S100-3 is a three-phase synchronous motor built by B&R Automation for the 8LS Synchronous Motors series. In automated machinery, this rotor-stator unit converts electrical drive commands into precise rotation that can be coupled directly to gearboxes or load shafts. By supplying regulated torque at cycle speeds demanded by servo drives, it forms a basic actuator for packaging lines, pick-and-place axes, and coordinated gantry modules. Its synchronous design also supports repeatable motion where the drive must maintain accurate shaft position during changing load conditions.

Electrical and mechanical interfaces follow the 8LSA configuration, which means the unit is supplied without reinforced bearings and uses the internal 8LSA designation. Power, feedback, and brake leads are merged into a single-cable solution that terminates in a standard connector, simplifying routing through cable carriers. The rectangular mounting flange measures 100 mm, so the motor seats directly on most IEC size-100 brackets. That mounting format suits compact machine frames where direct face attachment is preferred. At its rated operating point, the rotor reaches 3000 rpm, delivering stable velocity for mid-power axes. Rotor position is measured by an Inductive EnDat encoder, and the onboard interface complies with EnDat version 2.2 for absolute feedback and electronic nameplate functions.

In addition, the encoder outputs an absolute resolution of 19/12 bits for single-turn and multi-turn data, while the mechanical counter preserves position across up to 4096 revolutions in multi-turn operation. Thermal control relies on a self-cooling design with free air circulation, eliminating external blowers. The shaft is supplied with a key, the motor uses flange mounting, and it has length code 6. These features support direct connection to couplings and other driven components that require positive torque transfer. No holding brake or oil seal is installed, which reduces axial length and service parts. Internal configuration is tracked under product revision 3.
