Product Description:
The 8LSN45.EA030D000-0 is a three-phase synchronous servo motor from B & R Automation and belongs to the 8LS Synchronous Motors series. Within an automation cell, the motor converts drive current into rotational motion that can be precisely regulated by a servo amplifier. Its compact design supports controlled motion for indexing tables, pick-and-place heads, feed rollers, and other automated machine axes. The servo amplifier can regulate position, torque, and velocity in response to commands from the machine controller.
With a flange dimension of 100 mm, the motor mounts directly to compatible gear reducers or machine frames without requiring an adapter plate. Thermal management is handled by a self-cooling design, so the housing dissipates heat from the stator without an external fan. The windings support a rated speed of 3000 rpm, allowing the axis to operate at common industrial cycle rates without exceeding its intended speed range. Rotor position is reported by an inductive EnDat encoder that uses the EnDat 2.1 interface, providing absolute feedback at power-up and resistance to contamination. Power and feedback cables leave the stator through an angled connection that can be positioned to suit the cable route and reduce strain during installation.
The motor has a smooth shaft, allowing secure installation of clamping couplings where low backlash is required. It is supplied with no holding brake, so vertical or gravity-loaded axes require an external brake or another means of retaining the load when power is removed. The omission of an internal brake reduces rotating inertia and helps maintain the compact housing associated with length code 5. The rotor has an increased mass moment of inertia, which helps resist abrupt speed changes caused by intermittent cutting or forming forces. Its encoder provides single-turn capability with 19 bits of single-turn resolution for accurate angular position reporting. The motor uses the standard configuration code and does not include an oil seal, making it appropriate for installations where the shaft is not exposed to oil or other fluids.
