Product Description:

The 8LSA26.S5045D200-0 is a three-phase synchronous motor built by B&R Automation for the 8LS Synchronous Motors series. It provides rotary motion to axes where compact power density and coordinated servo control are required, such as feeders, pick-and-place heads, or small spindle drives in industrial automation cells. Power and feedback lines exit through an angled swivel connector, which helps route cables when space around the motor is limited. It is intended for coordinated motion tasks where the drive must regulate speed and position through repeated operating cycles. This makes it suitable for compact machine modules with closely spaced components and limited mounting space.

The motor develops a nominal output of 339 W at a rated torque of 0.72 Nm while operating at up to 4500 rpm. When short-term overload is required, it can reach a maximum torque of 3.2 Nm. A mounting flange with a diameter of 58 mm mates the housing to machine frames, and the smooth shaft supports connection to gears or pulleys. Four pole pairs support precise electrical commutation during servo operation. Self-cooling through free air circulation eliminates the need for external fans. The motor uses flange mounting, has a smooth shaft end without an oil seal, and comes with standard bearings rather than reinforced bearings.

Dynamic holding is provided by a standard brake with 2.2 Nm of holding torque. The brake adds an inertia of 0.12 kg·cm² and a mass of 0.45 kg. Without the brake, the rotor inertia is 0.2 kg·cm², and the total motor weight is 1.5 kg. The 8LSA designation, length code 6, and product revision 0 describe its mechanical version in the series. Because the shaft has no oil seal, the motor is better suited to clean environments where lubricant leakage and heavy contamination are not expected. The angled connector orientation also helps reduce tight cable bends near the motor housing.
