Product Description:

The 8LSA34.R0030D200-0 is a three-phase synchronous motor produced by B&R Automation within the 8LS Synchronous Motors series. The unit uses the 8LSA designation and length code 4 and is configured as a standard model without a reinforced bearing. It acts as a rotary actuator in automated machinery, converting drive current into tightly regulated torque and speed for positioning axes, conveyors, or process equipment in industrial environments. A smooth shaft simplifies direct coupling to gearboxes or pulleys.

At a rated speed of 3000 rpm, the motor delivers its nominal performance while remaining synchronized with the inverter output. Its electromagnetic design keeps torque production linear with current across the working range. Rotor position feedback is supplied by a resolver, which provides analog sine-cosine signals that withstand electrical noise and high temperatures. Thermal energy is removed through self-cooling with free circulation, allowing the housing to dissipate heat without external fans. For controlled stops and load holding, the unit incorporates a standard holding brake that engages automatically when power is removed. The absence of an oil seal reduces shaft drag and makes the motor suitable for clean, dry installations.

The mechanical interface uses a flange diameter of 91.3 mm, providing a compact footprint for machinery with limited installation space. Dynamic backlash is limited to 10 arcmin, providing the precision needed for medium-accuracy positioning tasks without imposing unnecessarily strict alignment requirements on connected equipment. Power and feedback leads exit through an angled swivel connector that can be rotated to relieve cable stress, while the supplied standard industrial mating hardware supports secure cable attachment and organized routing within the machine frame.
