8LSA44.EB060D200-0 by B & R Automation

The 8LSA44.EB060D200-0 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. Within an automation cell, it delivers rotary power for servo axes that require high-speed positioning and compact flange mounting. The motor supports inductive feedback through its EnDat interface, allowing precise closed-loop control when paired with a compatible drive controller. This arrangement suits indexing units, transfer axes, and other machines that need accurate speed and position regulation in a compact motor package.

The motor's maximum mechanical velocity is 6000 rpm, which is the upper operating speed before overspeed protection would intervene. A flange dimension of 100 mm matches common mounting patterns so the housing aligns directly to machine frames. Heat is removed by self-cooling through free air circulation, so no external blower or liquid jacket is required. Power and feedback conductors exit the stator through an angled swivel connector, easing cable routing in tight spaces and reducing strain during axis movement. Position data comes from an Inductive EnDat sensor that uses EnDat 2.1 communication, providing digital diagnostics and automatic parameter identification. The standard 8LSA build uses normal bearing support rather than reinforced bearings, and the lack of an oil seal means the shaft area should be kept away from lubricant splash.

For high-resolution motion tasks, the encoder supplies 19/12 bits of single-turn and multi-turn information, enabling fine incremental moves and absolute homing. Multi-turn capability extends to 4096 revs, allowing the control system to track position through multiple shaft rotations after power is removed. A standard holding brake engages when the drive is disabled to secure vertical loads or resist external torque. The motor is supplied with a smooth shaft, making it suitable for clamp or press-fit couplings that do not require a keyway. Connection hardware uses a single plug-style connector, and the stator mounts by flange without additional brackets.
