Product Description:

The 8LSA35.DB030S000-3 is a three-phase synchronous motor produced by B & R Automation for the 8LS Synchronous Motors series. Within an automation cell, it acts as a rotary actuator that converts drive current from a matched inverter into precise torque and speed for positioning or continuous-duty motion tasks on packaging lines, pick-and-place modules, or conveyor stations. Its connection hardware is a connector, which supports plug-in installation of the motor lead.

The motor follows the 8LSA configuration standard and has a housing without reinforced bearings. It uses a single-cable hybrid solution, so power, feedback, and brake lines are combined in one routed lead. Thermal management depends on self-cooling by free circulation, eliminating the need for forced air or liquid jackets. A flange face measuring 91.3 mm supports the mounting interface, allowing the unit to bolt directly to machine frames. Under rated conditions, the rotor reaches 3000 rpm, a speed matched to many servo drives on 50 Hz and 60 Hz mains. Position feedback is provided by a built-in Inductive EnDat encoder, and the 2.2 protocol revision supports bidirectional data exchange for parameter storage and diagnostics.

Encoder resolution of 19/12 (single/multi-turn bits) allows 524,288 discrete positions per revolution and absolute tracking across up to 4096 revolutions, supporting startup without a homing move. The motor has no holding brake, so a vertical axis must be secured by mechanical locking or drive torque when power is removed. The output is a smooth shaft, which simplifies coupling to low-backlash clamp hubs. An oil seal is not present, which should be considered in lubricated environments. Length code 5 sets the stator stack depth, and product revision 3 identifies the revision level for this model.
