Product Description:

The 8LSA46.DA030S100-3 belongs to the 8LS Synchronous Motors series from B&R Automation. It is a three-phase permanent-magnet motor intended for positioning and velocity tasks in automated machinery, where a compact frame and straightforward integration are required. Delivered without a holding brake, the motor couples directly to the driven axis through its keyed shaft and supplies continuous rotary power to conveyors, pick-and-place heads, or rotary tables within a broader motion-control system. Its compact format supports use where installation space is limited and repeatable servo motion is needed.

This motor uses a three-phase synchronous design and reaches a nominal speed of 3000 rpm, which suits medium-inertia loads in direct-drive or lightly geared applications. A square 100 mm flange provides the mechanical interface, while length code 6 indicates a medium stack height that supports a balanced relationship between torque output and overall motor size. Heat is removed through self-cooling with free air circulation, so the housing does not require external blowers or liquid jackets. Power and feedback signals are routed through a single-cable solution, which reduces wiring and helps limit electromagnetic interference inside the machine. A molded connector on the stator endplate completes the hybrid cable termination and keeps the motor connection compact at the installation point.

Rotor position is measured by an Inductive EnDat sensor that operates with protocol version 2.2. The feedback has a native resolution of 19/0 bits for single-turn and multi-turn data words, and the encoder supplies absolute angle information within one mechanical revolution. The product is in revision 3, and the motor uses flange mounting at the machine interface. The shaft has no oil seal, which reduces drag and suits clean, dry environments. This version uses the standard, non-reinforced bearing arrangement rather than a reinforced bearing set.
