8LSA57.E3022Z200-1 by B & R Automation

The 8LSA57.E3022Z200-1 is a servo motor from B&R Automation in the 8LS Synchronous Motors series. It is designed to provide repeatable torque and speed for positioning axes, packaging equipment, and other industrial motion tasks. The motor uses a laminated stator and permanent-magnet rotor to convert electrical input into controlled mechanical rotation. In automated systems, it supports controlled acceleration, steady running speed, and repeatable stopping behavior. Its compact servo format suits machines that need accurate response without a large installation footprint.

The motor uses self-cooling with free circulation, so heat is removed without an external fan. Because cooling relies on ambient air movement around the housing, installation does not require a separate fan assembly on the motor. The housing is built with a 142 mm flange, which supports direct mounting on compatible machine faces. Under nominal load, the shaft reaches 2200 rpm, which suits medium-inertia applications that need stable operating speed. Electrical connections are made through a connector, which keeps wiring straightforward and compact. The motor uses length code 7, which corresponds to a longer active stack for higher continuous torque.

The unit is supplied in the 8LSA standard configuration, which does not include oversized shaft bearings and helps keep rotating mass lower. It has no reinforced bearing, so radial loads should remain within the normal range for this motor type. This arrangement is suited to applications with ordinary mechanical loading rather than unusually high belt or overhung loads. Its three-phase synchronous design supports smooth torque production and accurate speed control when paired with a compatible servo inverter. The housing also includes a mounting flange for direct attachment to the machine structure. Direct flange attachment also helps maintain alignment between the motor and the driven mechanism.
