8LSA25.R0060D200-3 by B & R Automation

The 8LSA25.R0060D200-3 synchronous servo motor is built by B&R Automation and belongs to the 8LS Synchronous Motors series. As a compact rotary unit, it converts drive current into controlled torque for positioning and velocity loops in automated assembly lines, conveyors, and packaging equipment. The 8LSA designation identifies this variant as a standard configuration without reinforced bearings, making it suitable for general-purpose servo axes where moderate radial loading is expected.

The motor uses a flange dimension of 58 mm, allowing direct attachment to compact gearboxes or end effectors. Power and feedback lines exit through an angled connection that can swivel, which helps with cable routing inside tight machine frames, and the mating point is a sealed connector. A Resolver supplies continuous position data for the feedback loop, supporting repeatable motion within the stated precision range. Thermal management relies on a self-cooling free-circulation concept, so ambient air removes heat without external fans or liquid circuits and maintains full performance up to the rated speed of 6000 rpm. The length code 5 housing fits compact mechanical modules and supports installation in space-limited axis arrangements.

Motion accuracy is held within 10 arcmin, supporting coordinated multi-axis interpolation. A standard holding brake secures the shaft during power-off conditions and helps prevent drift on vertical axes. The transmission end uses a smooth shaft, so torque is transferred by friction couplings rather than keys, and no oil seal is present, which reduces drag during high-speed operation. Internally, the motor uses three-phase synchronous design principles, and the product is supplied in revision 3. All electrical power and feedback connections are consolidated in a single plug.
