Product Description:

The 8LSA46.R2030D100-3 is a three-phase synchronous motor built by B & R Automation for the 8LS Synchronous Motors series. It converts electrical power into mechanical torque for positioning and speed control tasks in industrial automation equipment such as gantries, packaging machines, and servo axes. This operating role makes it suitable for applications that require repeatable acceleration, deceleration, and accurate shaft response during motion. The designation 8LSA confirms a standard configuration without reinforced bearings, while product revision 3 marks the current manufacturing release. A keyed shaft end permits positive torque transfer to couplings or pulleys in closed-loop motion systems.

At a rated speed of 3000 rpm, the motor supplies constant output when driven by a matched inverter. Heat generated in the stator is removed by the housing itself because the unit relies on self-cooling, free circulation, so no external fan or liquid circuit is required. Rotor position and velocity are detected through a resolver, providing analog sinusoidal feedback that withstands shock and temperature better than optical devices. This feedback method also supports stable commutation and reliable motion control across changing operating conditions. The mounting interface follows a 100 mm flange pattern that aligns with IEC dimensions, and drivetrain backlash is limited by a positional precision of 6 arcmin between commanded and actual shaft angle.

The power and feedback leads exit through an angled connection that swivels to align with cabinet routing, and they terminate on a sealed connector interface supplied on the motor frame. This layout helps keep cable routing orderly and reduces exposed termination points around the machine. Because the unit is delivered without a holding brake, machines requiring static load retention must incorporate an external mechanical lock or active servo torque. The active section identified by length code 6 balances torque output with compact overall depth, while the absence of an oil seal restricts use to clean, dry zones or requires an external shaft sealing element.
