Product Description:
The 8LSA54.R2030D100-3 belongs to the 8LS Synchronous Motors series manufactured by B&R Automation. The internal 8LSA designation indicates the standard configuration without a reinforced bearing, providing a balanced relationship between load capacity and motor size. As a compact drive element, this motor supplies closed-loop axis motion for packaging fillers, pick-and-place arms, and other automation equipment where rapid, repeatable positioning is required. Its synchronous design allows a compatible drive controller to regulate torque, speed, and position throughout demanding motion cycles.
The motor is a three-phase synchronous unit with a nominal speed of 3000 rpm, supporting high-speed operation in automated machinery. A flange diameter of 142 mm forms the mounting interface and aligns the motor accurately with the connected machine. Heat is removed through self-cooling with free air circulation, so no external blower or liquid jacket is necessary. A resolver mounted on the stator supplies rotor position feedback to the drive controller, which uses the signal to calculate velocity and regulate motion. The housing has a mounting flange and accommodates a Length Code 4 stator stack. The motor is supplied without a holding brake, so an external mechanism or drive-applied torque must retain stationary loads when required. It also has no oil seal, which reduces friction but requires an installation environment that does not expose the shaft opening to oil or other contaminants.
Mechanical accuracy is rated at 6 arcmin, supporting precise indexing without requiring a secondary encoder. Power and feedback conductors exit through an angled connection, allowing the cables to run parallel to the machine frame with less bending stress near the motor housing. The motor has a keyed shaft, which provides positive torque transfer to a compatible coupling or pulley. The unit is Product Revision 3, so its cabling and connector components should be selected for this revision. Connection hardware is supplied as a standard industrial connector, providing a secure interface for the required power and feedback wiring. Appropriate strain relief should support the routed cables and prevent movement at the connector during repeated machine cycles.
