Product Description:

The 8LSA55.EB030D200-3 synchronous motor is manufactured by B & R Automation for the 8LS Synchronous Motors series. It is intended for servo axes that demand accurate speed and position control in automated packaging, material handling, and assembly equipment. The 8LSA designation indicates a standard construction without reinforced bearings, and the mounting flange allows direct attachment to a machine frame or gearbox. This arrangement supports compact installation where repeatable alignment is important.

The motor uses a three-phase synchronous design that supplies torque in proportion to drive frequency. Its rated speed of 3000 rpm marks the maximum continuous shaft velocity and helps when estimating cycle times for the axis. A 142 mm flange dimension provides the mounting interface. Position feedback comes from an Inductive EnDat sensor that delivers absolute data and resists dust contamination. Heat is removed by self-cooling airflow through the housing, so no external fan is required. The swivel angled connection directs cables toward the machine interior, and the integrated connector supports orderly routing in confined installations. Field cabling strain relief is provided by the molded hood.

The encoder communicates through EnDat 2.1, enabling fast serial updates between the motor and drive. Its 19/12-bit resolution supports precise single-turn and multi-turn indexing, and memory stores up to 4096 multi-turn revolutions so position can be retained after power loss. A standard holding brake keeps the load fixed when the inverter is disabled. Additional details include length code 5 for the active stack, product revision 3, a smooth shaft end for backlash-free coupling, and an angled connector housing for lateral wiring. The motor does not include an oil seal, so it is better suited to clean, dry areas. The standard build without reinforced bearings is intended for applications with moderate radial forces.
