8LSA34.EA060D100-3
B&R Automation manufactures the 8LSA34.EA060D100-3 as part of its 8LS Synchronous Motors series. This three-phase synchronous motor drives industrial positioning tasks by converting inverter output into tightly regulated torque and speed. Intended for servo axes on assembly cells and packaging stations, it attaches through a mounting flange and uses the standard 8LSA mechanical build without reinforced bearings to minimize mass and shorten acceleration times in repetitive machine cycles.
The motor’s electrical core is rated for 6000 rpm, giving axis controllers a high top-speed range while maintaining synchronism between the stator field and rotor magnets. Heat generated at that speed is removed by self-cooling with free circulation, so no external blower or liquid loop is required. This cooling method keeps the motor layout simple and avoids added auxiliary hardware around the axis. Power and feedback conductors exit through an angled swivel connector that simplifies cable routing in tight cabinets. A flange face of 91.3 mm sets the bolt pattern and centers the shaft consistently against gearboxes or pulleys. Position feedback is delivered by an Inductive EnDat encoder, enabling absolute position reporting with good resistance to dust and vibration.
Internally, the encoder uses protocol version 2.1, allowing the drive to access diagnostic and temperature data over the same serial link. The single-turn tracking capability pairs with a resolution of 19/0 bits, which supplies 524,288 discrete positions per revolution without multi-turn counting. Because a mechanical brake is not present, the axis must rely on drive torque or external clamps when power is removed. The output shaft is machined with a key for positive torque transmission, which supports secure coupling to driven components. This version is identified by length code 4, product revision 3, and a housing without an oil seal for installations where sealing is provided by connected machinery.
