8LSA37.DB060S000-3 by B & R Automation

B & R Automation manufactured the 8LSA37.DB060S000-3 three-phase synchronous motor in the 8LS Synchronous Motors series. The 8LSA designation identifies a standard build without reinforced bearings, and the product is revision 3. When paired with a compatible AC servo drive, this motor supplies high-speed rotation for indexing tables, gantries, and other precise axes in industrial automation environments. A mounting flange on the stator frame permits direct installation on machine plates.

The motor achieves a rated speed of 6000 rpm, allowing rapid cycle times where short positioning intervals are needed. Its flange dimension measures 91.3 mm, so the mechanical interface matches compact gearboxes or belt drives within that shaft circle. Electrical power and feedback travel through a single-cable solution that terminates in a keyed connector, reducing cabinet wiring and preserving EMC performance. Position feedback is generated by an Inductive EnDat encoder that uses EnDat version 2.2; this protocol transfers absolute position data and diagnostic words to the inverter. The encoder provides 19/12 bits of resolution for single-turn and multi-turn counts, supplying fine angular granularity over the entire measuring range.

Thermal management relies on self-cooling through free circulation; no external fan or liquid circuit is required, which simplifies installation where airflow is available. The feedback system supports 4096 revolutions of multi-turn tracking, letting the axis recover absolute position after power loss without a homing move. A smooth shaft eases coupling to clamping hubs and contributes to lower vibration because no keyway interrupts the fit. The motor uses length code 7, giving a rotor package that balances torque against inertia for mid-range loads. Because no holding brake or oil seal is fitted, external load-holding measures are required, and the motor is not intended for applications with pressurized lubricants.
