8LSA84.S1030D200-0 by B & R Automation

The 8LSA84.S1030D200-0 is a rotary motor manufactured by B&R Automation for the 8LS Synchronous Motors series. It is used as a drive element in automated assembly, material-handling, and packaging cells where precise rotary positioning is required. The three-phase construction converts inverter current into torque, and an optical feedback channel allows the controller to read exact shaft position and speed. When coupled to a servo amplifier, the unit converts motion commands into controlled mechanical rotation for continuous-duty industrial axes. This arrangement supports repeatable movement in systems that require both positioning accuracy and stable speed control.

The motor reaches a rated speed of 3000 rpm, allowing direct coupling to common gear stages without overspeed. A self-cooling design that relies on free air circulation removes copper and iron losses, and the 8LSA configuration indicates that no reinforced bearing is fitted. The square mounting face measures 240 mm, matching the flange arrangement used for this motor size. Feedback is generated by an optical EnDat encoder that operates with protocol version 2.2, and its resolution is 25/12 bits for single-turn and multi-turn position values. Power and feedback conductors exit through an angled swivel connector, which helps keep cable loops compact inside the cabinet. That connector orientation can also simplify routing where space around the motor is limited.

A standard holding brake secures the rotor during standby and helps prevent drift on vertical axes. Position tracking through power interruptions is maintained by the encoder's multi-turn 4096 revs capability. The stator uses a three-phase synchronous winding to supply constant torque with sinusoidal current demand. The shaft is smooth rather than keyed, so it mates directly with clamping hubs, and there is no oil seal, so the installation should be kept away from lubricant splash. This arrangement is suited to applications that use a clean coupling area and do not require a sealed shaft end.
