8LSA45.E2030D300-0 by B & R Automation

The 8LSA45.E2030D300-0 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. Built on the 8LSA configuration, it uses standard bearings rather than a reinforced set, which helps keep moving mass lower for dynamic axes. Within an automation cell, the motor works with a matching servo inverter to deliver the controlled torque, speed, and position response needed for pick-and-place, conveyor, or indexing functions. Because it is a synchronous design, it is suited to closed-loop motion tasks that need stable speed regulation and accurate stopping points during repetitive machine cycles.

Cabling exits the housing through an angled swivel orientation that eases strain when the motor sits inside tight cable carriers, and the power and feedback lines terminate on a quick-release connector for compact connection and removal. Heat is removed through a self-cooling design with free air circulation that relies on ambient airflow and eliminates the need for external fans. The front face follows a 100 mm square flange pattern, which fits common gearboxes and machine plates. A standard holding brake is integrated to lock the shaft during power-off sequences, supporting vertical or intermittent load conditions without external clamping devices. This model is a standard 8LSA build, so no additional bearing reinforcement is included.

Axial length uses code 5, giving the motor a longer stator stack for higher torque without changing the flange outline. Continuous operation is supported up to 3000 rpm, matching many servo drive output tables for direct coupling to 1:1 gear ratios and other speed-matched transmissions. Installation uses a precision-machined mounting flange, which helps align the motor with reducers or belt-driven components. The shaft end is supplied with a key to transmit torque through keyed couplings, and no oil seal is fitted, so an external barrier is needed when fluids or washdown exposure are present.
