8LSA44.DB030S200-3 by B & R Automation

B&R Automation builds the 8LSA44.DB030S200-3 as part of the 8LS Synchronous Motors series. This three-phase synchronous motor is intended for direct mounting on machine axes where precise velocity and position control are required in industrial handling and assembly systems. Its layout suits servo applications that need repeatable motion over frequent operating cycles. The compact motor arrangement also helps when installation space around the axis is limited.

The motor reaches a rated speed of 3000 rpm, which suits many servo drive applications that need stable high-speed operation. Position feedback is supplied by an inductive EnDat encoder, providing absolute position data with consistent signal quality. Power, feedback, and brake conductors are combined in a single-cable hybrid solution, which reduces cable routing complexity at the machine. Thermal management relies on self-cooling through free circulation, so no external fan or liquid circuit is required. A mounting flange with a face dimension of 100 mm helps align the housing with common machine interfaces. The motor also uses a smooth shaft end for backlash-free coupling to the driven mechanism.

A standard holding brake secures the load when drive power is removed, which is useful on vertical axes and other applications that need load retention. The encoder offers 19/12 bits of single-turn and multi-turn resolution, and it supports a multi-turn capability of 4096 revolutions without battery backup. The shaft area has no oil seal, so it should not be exposed to pressurized coolant or direct oil spray. The 8LSA designation indicates a standard configuration without reinforced bearings, and the motor uses the standard bearing arrangement for this version. The motor has length code 4, connector hardware for the cable interface, and product revision 3.
