Product Description:

B & R Automation supplies the 8LSA34.E3030D000-0 as part of its 8LS Synchronous Motors series. This compact servo unit is intended to produce controlled torque and speed for axes in packaging lines, pick-and-place gantries, and general motion control stations. By integrating into a closed-loop drive system, the motor converts electrical power from the controller into rotary motion that can be precisely commanded during automated cycles.

Thermal management relies on self-cooling with free circulation, so the housing dissipates heat directly into ambient air without auxiliary devices. A flange dimension of 91.3 mm sets the fastening pattern and centers the motor on adjoining machine frames. With a rated speed of 3000 rpm, the rotor supports rapid indexing while staying within the permitted mechanical limit. Installation uses a mounting flange that carries axial loads and aligns the shaft relative to driven components. Power is transferred through a smooth shaft, which avoids keyway stress concentrations and is suited for clamp or compression couplings that rely on frictional engagement. Because the configuration uses the standard bearing arrangement, radial load capacity follows the normal values for this motor design.

The motor has no holding brake, so external mechanical retention is required if the axis can be back-driven when power is removed. A single quick-disconnect connector is mounted at an angle on a swivel, which helps route cables away from confined mounting spaces and reduces bend stress. The housing uses length code 4, representing the active stack height selected for medium torque demand. Internally, the motor uses a three-phase synchronous winding, allowing field-oriented control with sinusoidal currents. The design omits an oil seal, and the angled connection direction helps keep the cable exit compact.
