Product Description:
B & R Automation manufactures the 8LSA55.E1030D200-3 in the 8LS Synchronous Motors series. The 8LSA designation indicates a standard configuration without a reinforced bearing, making the motor suitable for general-purpose axes in packaging cells, gantries, and material transport. Using a three-phase architecture, the unit converts output from a matched inverter into controlled torque for closed-loop motion tasks in industrial automation lines. It mounts by a flange and uses a smooth shaft, allowing connection to belts, pulleys, or direct drives without additional machining.
The rated speed reaches 3000 rpm, giving the axis a moderate velocity range before field weakening is required. A flange dimension of 142 mm establishes the mounting footprint and sets the center height relative to adjacent machine elements. Position feedback comes from an Optical EnDat encoder, and the version 2.1 interface sends absolute data directly to the servo drive. Its digital resolution is 13/12 bits for single-turn and multi-turn tracking, and the multi-turn range extends across 4096 revs. This feedback supports fine velocity regulation and repeatable homing after power loss.
The motor uses self-cooling with free circulation, so airflow around the housing maintains thermal limits without external fans or liquid jackets. Power and feedback lines exit through an angled swivel connector that mates with standard circular plugs and helps cable routing in tight spaces. Motion can be held at standstill by the standard holding brake, which helps prevent drift on vertical axes when power is removed. This model is released as product revision 3. A length code of 5 corresponds to the active stator stack, and the absence of an oil seal means the shaft area should be kept away from lubricants during operation.
