Product Description:

B & R Automation produces the 8LS Synchronous Motors series, and the 8LSA44.EA030D000-0 belongs to this line as a standard configuration motor without reinforced bearings. Classified for use in servo axes, the unit converts electrical energy into rotary motion for precise positioning tasks in industrial automation cells, packaging machinery, and material handling stations. Its mounting flange lets system builders fix the stator directly to a machine frame, while feedback from an integrated encoder feeds the drive controller to close the speed and position loop.

The motor uses a three-phase synchronous design, so its torque is generated by a rotating magnetic field that stays in step with the stator excitation. The rated speed is 3000 rpm, which is the upper continuous mechanical velocity the axis can sustain without derating. Position feedback relies on an Inductive EnDat sensor that uses the EnDat 2.1 protocol and provides absolute position data to the drive every cycle. Inside that sensor, a resolution of 19/0 bits supplies single-turn accuracy with no multi-turn counting, which is suitable for short-stroke or homed applications. Heat is removed through self-cooling, meaning convection around the housing is enough and no external fan or liquid circuit is required.

Electrical connections exit through an angled swivel plug, and power and signal conductors mate to a keyed connector that can be uncoupled without disturbing the motor. The interface to the machine frame is a flange with a diameter of 100 mm, aligning with IEC size 100 mounting dimensions. A smooth shaft simplifies coupling because no keyway or spline is present, letting it work with clamp hubs or shrink discs. The motor is built without an internal holding brake, so static load retention must be handled by the drive or external mechanics, and its oil seal is omitted to suit dry-room environments.
