Product Description:

The 8LSC55.E3030D305-1 is a three-phase synchronous servo motor produced by B&R Automation and assigned to the 8LS Synchronous Motors series. Within that series, the 8LSC designation identifies models equipped with a 230 VAC auxiliary fan for forced-air cooling. Installed on motion axes, the motor converts drive current into precise torque and speed so packaging, assembly, and robotics equipment can hold position accurately and cycle at commanded velocities. This operating profile suits machinery that depends on repeatable starts, stops, and steady speed control during continuous production.

Power and feedback connections are arranged to support compact machine layouts and orderly cable routing. The leads exit through an angled swivel connection block that helps reduce cable strain in tight enclosures, and the terminations use a detachable connector for easier connection and removal. Thermal management is handled by a built-in fan assembly, which provides forced airflow so the stator can remain within safe operating limits during continuous loading. The motor mounts with a flange diameter of 142 mm, and its rotor can reach a rated speed of 3000 rpm when the fan is operating. This cooling method helps the motor sustain consistent output during repetitive motion cycles.

A standard holding brake keeps the shaft locked during power loss so vertical axes do not drift. The windings use three-phase synchronous construction, which supports stable torque production when the motor is driven by a matched inverter. A rigid mounting flange is integrated into the front face, and torque is transferred through a keyed shaft end for secure coupling to driven components. The motor has no oil seal, so it should be installed outside direct spray zones or used with external sealing where lubricant exposure is expected. Length Code 5 provides the housing depth used for this model within the series.
