8LSA44.DA022S700-3 by B & R Automation

The 8LSA44.DA022S700-3 servo unit is produced by B&R Automation as part of the 8LS Synchronous Motors series. It is a three-phase machine intended to drive positioning axes, conveyor sections, and other motion elements in industrial automation lines. The 8LSA designation identifies the standard version without reinforced bearings, and revision 3 keeps the established housing style while using a connection arrangement suited to hybrid motor cabling. This layout supports compact installation where motor power and feedback must be routed with minimal cable clutter.

Mechanical integration is supported by a flange diameter of 100 mm and a keyed shaft end that transmits torque securely to the driven load. The motor uses self-cooling with free air circulation, so no external fan or liquid cooling circuit is required during normal operation. Power and encoder feedback are combined in a single-cable solution through a molded connector, which reduces the number of separate leads at the motor. Position data comes from an inductive EnDat sensor that supports EnDat 2.2 and provides 19/0 bits of single-turn and multi-turn resolution. The electrical design supports continuous operation at 2200 rpm, and the motor is supplied without a holding brake, so load holding must be handled by the driven mechanism or external braking hardware.

The motor uses a three-phase synchronous design for controlled torque production across its rated operating range. Installation is done through a mounting flange with a standard bolt circle, and the shaft is fitted with an oil seal to help limit lubricant migration during long duty cycles. The connection hardware uses a right-angle connector shell, and the standard bearing arrangement means radial loads must remain within the normal limits for the 8LSA version. These features suit applications that need compact servo installation, direct flange mounting, and integrated feedback in a single motor connection.
