Product Description:

The 8LSA35.EA030D000-3 synchronous motor is manufactured by B&R Automation and belongs to the 8LS Synchronous Motors series. The unit is a three-phase permanent-magnet machine intended for direct coupling to compatible AC servo drives. When installed on pick-and-place bridges, index tables, or compact gantries, it supplies regulated torque and repeatable shaft position so sensors and actuators remain aligned with programmed motion profiles. It is suited for closed-loop motion tasks that require accurate speed control and consistent positioning in compact automation equipment.

The motor reaches a rated speed of 3000 rpm, allowing the driven axis to complete rapid positioning cycles without exceeding the thermal capacity of the winding set. Heat is removed by a self-cooling principle that relies on free air circulation, so no external fan or liquid jacket is required. A mounting flange with a diameter of 91.3 mm centers the housing on the machine frame and sets the bolt circle for repeatable installation. Power and feedback leave the housing through a removable connector, allowing quick cable disconnection when the motor is installed in confined spaces. The unit is supplied with no holding brake, so the load must be secured by external mechanical restraint or drive torque during power loss.

Position data is generated by an Inductive EnDat sensor that delivers absolute feedback to the drive. The protocol runs on version 2.1, supporting high-resolution communication without a separate encoder interface. Cables exit the stator through an angled swivel outlet, which helps routing in tight panel heights while maintaining strain relief. A smooth shaft supports low-backlash couplings to gears or belt pulleys, and the uninterrupted shaft surface avoids the discontinuity created by a keyway. This layout is useful when the motor is mounted close to guards or other machine structures.
