Product Description:
The 8LSA44.R2045D100-3 is a synchronous servo motor with a 100 mm flange. This is one of B & R Automation's 8LS Synchronous Motors. It can go up to 3000 rpm. It cools itself using natural convection and has a maximum torque of 27.6 Nm. Operators appreciate this cushion during punchy brake throws or unexpected jams, certain in the knowledge that the windings will survive the momentary heat spike. In industries marked by erratic load profiles, such margin translates directly into reduced unplanned downtime.
Proprietary magnetic segmentation within the rotor teeth mitigates normal cogging, yielding ripple magnitudes several decibels below conventional thresholds. The result is motion that appears liquid rather than mechanical, a prerequisite in tasks ranging from precision EDM to high-fidelity robotic assembly. The machine feels as if it possesses its own sensory feedback loop. A recent analysis confirms that the machine maintains substantial torque output at elevated rotor velocities. Such behavior is essential in control scenarios where rapid spin and fluctuating loads occur simultaneously.
By sustaining this characteristic, the motor exhibits the responsiveness and utility demanded by modern, high-drill-performance installations. Inside the motor, a set of "preloaded ball bearings" is tensioned to get rid of any radial motion. This preinstalled element also helps improve rotational precision of the servo motor. The inner races include grooves throughout their length that help distribute loads more uniformly as torque changes. Both sides of each bearing have a metal seal that keeps dirt and moisture out. The assembly comes with oil from the manufacturer, so it doesn't need much maintenance for years. When it comes to protection, this servo motor comes with IP65 safety rating.
