8LSA44.E3030C100-0 by B & R Automation

The 8LSA44.E3030C100-0 is a three-phase AC servo motor produced by B&R Automation for the 8LS Synchronous Motors series. Identified by the 8LSA designation, this model serves as a drive element in automated machinery where precise torque and speed regulation are required for axes controlled by digital servo amplifiers. Its standard build without reinforced bearings suits general-purpose motion tasks such as pick-and-place modules, conveyors, and compact packaging units.

This motor reaches a rated speed of 3000 rpm, allowing direct coupling to loads that need constant high-speed rotation. A flange dimension of 100 mm sets the mounting interface and matches equipment standardized for that bolt circle. The electromagnetic system uses a three-phase synchronous design, so rotor position remains aligned with the stator field for consistent torque production at variable frequencies. Heat is removed through self-cooling with free air circulation, eliminating auxiliary blowers or liquid jackets. Electrical power and feedback leads exit through a straight top connector, which can simplify cable routing where vertical clearance is available. The housing includes a mounting flange, and the connection hardware uses a sealed circular connector for secure attachment. Radial and axial loads should remain within the permitted limits for the standard bearing arrangement.

The motor is supplied with no holding brake, so position retention during power loss must be handled by the drive or external locks. It is also built without an oil seal, so the shaft area should not be exposed to pressurized lubricants or heavy splash conditions. The frame uses length code 4, which provides a rotor stack sized for the stated torque without excessive overall depth. Power is transmitted through a keyed shaft end, enabling positive drive coupling to gears, pulleys, or rigid couplings while helping prevent slip during intermittent load reversals.
