8LSA46.R0030D000-0 by B & R Automation

The 8LSA46.R0030D000-0 is a motion-control motor produced by B&R Automation within the 8LS Synchronous Motors series. It functions as an electromechanical actuator that delivers regulated torque and speed to machine axes through a servo drive interface used in industrial automation cells. In normal operation, the paired drive regulates current according to motion commands so the motor can support positioning tasks and continuous rotary movement. This makes the unit suitable for general machine axes where controlled motion and compact installation are required.

It reaches a rated speed of 3000 rpm, allowing general-purpose axes to match standard servo-inverter frequency outputs. Position accuracy is supported by a precision of 10 arcmin, which indicates the maximum mechanical deviation between the commanded and actual shaft angle. A resolver provides rotor position feedback for the control loop during operation. The motor mounts through a 100 mm flange, and the power and feedback leads exit through an angled (swivel) connector arrangement with a circular mating interface for easier cable routing in compact machine spaces. Heat is removed by self-cooling with free air circulation, so no auxiliary fan is required. The motor also uses length code 6, which indicates a medium housing length in this series.

The motor does not include a holding brake, so any static load must be secured by drive torque or by an external mechanical brake. It uses a three-phase synchronous electromagnetic design, and torque is transmitted through a smooth shaft. The standard configuration does not include a reinforced bearing, so axial and radial load limits follow the basic bearing set. No oil seal is installed at the shaft collar, and the mounting flange provides the alignment reference for attachment to the machine frame.
