Product Description:

The 8LSA34.R0030D000-0 is a servo motor produced by B & R Automation for the 8LS Synchronous Motors series. Within automated cells, the unit converts drive controller output into precisely timed rotary motion that positions indexing tables, conveyor rollers, or multi-axis gantries. It follows the manufacturer’s 8LSA configuration, which uses standard construction without a reinforced bearing, so it is intended for general motion tasks rather than applications with extreme side loads. By supplying controlled torque and speed, the motor can replace pneumatic or hydraulic actuators where electronic synchronization and repeatability are required.

Its electromagnetic design is three-phase synchronous, keeping torque ripple low while the resolver supports electronic commutation. A rated speed of 3000 rpm allows the rotor to be coupled directly to moderate gear ratios without exceeding common mechanical limits. The front face carries a square flange measuring 91.3 mm, providing a predictable fit for compatible mounting layouts. Heat is removed through self-cooling with free air circulation, eliminating the need for external blowers or liquid cooling jackets. Power and feedback lines exit through an angled swivel connector that can be rotated during installation, allowing cable loops to be arranged with minimal strain.

An integrated resolver provides rotor position feedback, and total system accuracy is specified at 10 arcmin. The overall motor length is indicated by length code 4, balancing continuous torque capability with the unit’s footprint and mass. Output torque reaches the load through a smooth shaft, so a clamping coupling is required because the shaft does not have a keyway. The motor is supplied without a holding brake, so an external restraint is necessary when a vertical axis must remain stationary after power is removed. It is also supplied without an oil seal, requiring a separate sealing element when the shaft may be exposed to lubricant.
