8LSA45.E0022D200-0 by B & R Automation

The 8LSA45.E0022D200-0 is a three-phase synchronous servo motor produced by B&R Automation within the 8LS Synchronous Motors series. It serves as a rotary actuating element in industrial automation, converting inverter current into controlled torque and speed for machine axes, handling modules, and packaging lines. The design follows the 8LSA configuration and is intended for applications that require precise motion without reinforced bearing support. It is intended for closed-loop operation with a compatible servo inverter. This type of motor is commonly used where repeatable acceleration, deceleration, and positioning are needed in a compact drive package.

The motor has a rated speed of 2200 rpm for continuous operation. Its mounting interface uses a 100 mm square IEC flange that centers the stator on the machine frame and supports direct face mounting. Heat is removed by self-cooling, which relies on ambient air moving along the housing fins instead of an external fan. Rotor position is measured by an optical EnDat encoder that communicates over the EnDat 2.1 digital link for absolute feedback to the drive. Power and signal leads exit through an angled connection that can swivel, helping keep cable routing compact and reducing strain on the wiring.

A pluggable connector on the swivel fitting allows quick cable connection at the motor and keeps the interface easy to access. The motor has no reinforced bearing, which suits moderate belt or gear loads. It uses a smooth shaft, and a factory-installed standard brake provides holding torque when power is removed. The single-turn optical system uses 13/0 resolution, which provides 8,192 discrete positions per revolution without multi-turn counting. Length code 5 sets the active stack height, and the lack of an oil seal limits the motor to dry environments.
