Product Description:
The 8LSA54.R0030D000-0 is a three-phase servo motor produced by B&R Automation for the 8LS Synchronous Motors series. Within an automation cell, this unit converts drive current from the controller into rotational motion that can be regulated for positioning, indexing, or continuous-speed operation on conveyors, pick-and-place axes, and packaging spindles. Its standard 8LSA mechanical configuration supports direct flange mounting to machine frames, allowing the motor to act as a compact power element wherever precise closed-loop feedback is required.
The shaft can reach a rated speed of 3000 rpm, giving the drive train sufficient capacity for rapid acceleration while retaining torque at nominal speed. A flange pitch circle of 142 mm establishes the bolt pattern, so gearboxes or belt-drive components with matching dimensions can be fastened without adapters. Positioning repeatability is maintained within 10 arcmin, which is suitable for most pick-and-place or flow-wrap stations that do not require sub-arcsecond accuracy. Heat generated in the stator is removed through self-cooling by free air circulation, eliminating the need for external blowers or liquid cooling jackets. Rotor position is monitored with a resolver, which supplies analog sine-cosine signals that tolerate electrical noise and the high temperatures found near production equipment.
Cabling exits the housing through an angled swivel connector, allowing the plug to be rotated to reduce cable strain where installation space is limited. Electromagnetic energy is produced by a three-phase synchronous winding set, providing constant torque over the electrical cycle and reducing vibration compared with asynchronous designs. Power is delivered through a smooth shaft, and the absence of a keyway simplifies coupling to shrink-fit collars or clamping hubs. For axes that must coast freely when de-energized, the motor is supplied with no holding brake, so another method is required if the load must remain stationary without drive power. No oil seal is fitted, so external protection should be provided when the motor is used near oil, coolant, or other process fluids.
