8LSA54.R2030D100-3 by B & R Automation

B&R Automation produces the 8LSA54.R2030D100-3, a three-phase synchronous motor in the 8LS Synchronous Motors series. Designed for industrial automation, the unit converts electrical energy into controlled mechanical torque for positioning tasks and continuous-duty axes. When paired with an AC inverter, it supports feedback-based speed regulation for conveyor sections, pick-and-place heads, and packaging spindles. Its compact housing mounts directly to machine frames through a standardized IEC flange, which helps it fit installations where space around the axis is limited.

The motor has a nominal speed of 3000 rpm, allowing standard inverters to handle moderate inertia loads while maintaining stable speed control. Heat is removed by self-cooling with free circulation, so no external blower is required and surrounding machine layouts stay simpler. A 142 mm flange forms the mounting interface, and a resolver provides rotor position feedback for closed-loop control during speed and positioning tasks. Cabling exits through an angled connection, with power and feedback combined in one connector to reduce cable routing space at the motor. Positioning accuracy is rated at 6 arcmin, and the keyed shaft supports direct coupling; because no holding brake or oil seal is installed, the motor is best suited for dry mounting locations where static load retention is handled elsewhere.

The motor uses the 8LSA standard configuration, which omits reinforced bearings while remaining suitable for typical belt tension in common machine layouts. It has length code 4, indicating a longer stator stack than shorter versions of the same diameter and supporting higher continuous torque within this frame size. The unit is built to product revision 3, and its flange and connector arrangement follow the established layout of the 8LS platform for consistent integration with compatible motion systems.
