Product Description:
The 8LSA35.E2030D100-0 is a servo-class AC motor produced by B&R Automation within the 8LS Synchronous Motors series. As a rotary actuator, it converts electrical energy into controlled shaft torque and speed for indexing tables, packaging lines, and gantry axes in industrial automation. The model belongs to the 8LSA configuration subset and uses a standard bearing arrangement without reinforcement. It pairs with compatible inverters to execute the precise position control required by multi-axis equipment. This arrangement allows the drive to regulate motion as operating loads and speed commands change.
The motor has a rated speed of 3000 rpm, at which it can deliver continuous torque without exceeding its thermal limits. Heat is removed through self-cooling with free air circulation, so no external blower or liquid cooling jacket is required. Electrical and feedback conductors exit the stator through an angled swivel interface, which allows flexible cable routing in compact installations. The motor uses a mounting flange with a pilot diameter of 91.3 mm, providing a repeatable reference surface for gearboxes or direct-drive couplings. Accurate alignment at the mounting surface helps reduce stress on the shaft, bearings, and connected equipment during operation.
The motor uses a three-phase synchronous design, allowing sinusoidal current from the inverter to synchronize with the rotor field and minimize torque ripple. It has no holding brake, so an external mechanism must retain the shaft when power is removed from an application that cannot permit movement. The motor has a keyed output shaft, which provides positive torque transmission to pulleys, gearboxes, or rigid hubs without relying only on friction. Power and signal lines mate through a sealed connector, allowing the motor cables to be detached without opening the housing. The length code 5 housing does not include an oil seal, which reduces shaft drag while maintaining the intended enclosure protection. This shaft arrangement is suitable for installations where the coupled equipment does not expose the motor interface to oil.
