The B&R 8LSA46.R2030D100-3 is a 400 VAC synchronous servo motor for medium-torque industrial motion axes that require a keyed mechanical connection and resolver-based feedback.
This 3000 rpm motor delivers 7.700 Nm nominal torque and can reach 38.000 Nm maximum torque during dynamic machine movements. The keyed 19 mm shaft is suited to pulley, gearbox, coupling, and belt-drive assemblies where positive torque transmission is required.
Unlike the D200 brake version, this D100 configuration has no holding brake. It is therefore best suited to horizontal axes, rotary mechanisms, conveyor drives, and machine assemblies where the axis does not need to be mechanically held after power removal.
The motor uses an R2 two-pole resolver for feedback and should be matched with a compatible B&R servo drive configured for resolver operation. It is a servo motor only and should not be described as a PLC, servo amplifier, power supply, bus module, or variable frequency drive.
