Product Description:

The 8LSA35.DB030S300-3 is a three-phase synchronous motor from B&R Automation in the 8LS Synchronous Motors series. It delivers controlled torque for positioning axes on packaging, material-handling, and assembly machines. The 8LSA configuration indicates a standard build without reinforced bearings, while length code 5 indicates the stator stack depth. Product revision 3 identifies the current mechanical release, and the integrated mounting flange allows the motor to bolt directly to a machine frame without adapter plates.

The motor has a rated speed of 3000 rpm, which is the continuous operating speed supported by the drive system. A flange size of 91.3 mm matches common IEC mounting faces for straightforward installation. Motor power, brake supply, and encoder signals share one hybrid lead in a single-cable solution, and a molded connector on the housing provides the mating interface. Waste heat leaves the frame through self-cooling, so no external blower or coolant circuit is required. Rotor position is detected by an Inductive EnDat sensor that resists magnetic interference and sends absolute feedback data to the controller.

A standard holding brake secures the shaft when DC power is removed, which supports vertical or indexing loads. The feedback device provides absolute position information in a 19/12-bit single-turn and multi-turn format, and its internal counting electronics track up to 4096 revs so the axis retains position reference after power-up. Communication uses EnDat 2.2, which supports automatic parameter transfer and diagnostic functions. The motor has a keyed shaft end for torque transfer, and it comes without an oil seal to reduce friction in dry environments. Installation is through the mounting flange, and cooling relies on free air circulation around the housing during operation.
