8LSA35.R0045D000-0 by B & R Automation

The 8LSA35.R0045D000-0 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. It uses the 8LSA designation and follows the standard configuration without a reinforced bearing, balancing compact size with normal load support in automated handling stages. The motor provides continuous rotation and precise position control for conveyors, pick-and-place heads, and other motion axes in industrial automation cells where compact electric drives are preferred over pneumatic actuators. Its synchronous design supports closed-loop speed and position control when paired with a compatible servo drive.

The rated shaft velocity reaches 4500 rpm, allowing the drive to match medium-speed packaging spindles without mechanical gear reduction. A flange outer square of 91.3 mm establishes the interface outline and helps center the motor with minimal misalignment during installation. Cable exit uses an angled swivel orientation, and the power and feedback lines terminate on a single connector to simplify wiring in tight spaces. Heat is removed by self-cooling, which relies on free air circulation rather than an auxiliary fan or liquid circuit. Using one connection point keeps the motor body compact, and length code 5 corresponds to the stator stack selected for this speed and torque combination.

Mechanical integration uses a mounting flange, and torque is transferred through a smooth shaft that accepts custom couplings without keyway backlash. That shaft style is well suited for direct coupling to pulleys, screws, and other transmission elements that benefit from low play. Position feedback is generated by a resolver, which tolerates vibration and elevated temperatures while still achieving a repeatability window of 10 arcmin. Because no holding brake is installed, static torque must be provided by the drive amplifier when power is removed. The absence of an oil seal makes this model better suited for clean, dry enclosures than for lubricated gearbox connections.
