Product Description:
The 8JSA22.E9080D000-0 synchronous motor is produced by B & R Automation and belongs to the 8JS Synchronous Motors series. It serves as a torque source for axis control in automated machinery, converting drive current into regulated mechanical motion for packaging, assembly, and material-handling equipment. Its compact stator geometry helps integrate the motor into multi-axis gantries where space and weight must be minimized. The motor can support positioning and speed-control tasks when paired with a compatible drive controller.
The device has a motor size of 2, a length code of 2, and a maximum nominal speed of 8000 rpm. Position feedback is supplied by the inductive EnDat 2.1 system, which provides an angular precision of ±280 arcsec. The encoder provides 18/12-bit resolution for single-turn and multi-turn position data, respectively. Absolute position can be tracked across 4096 revolutions before the position data rolls over. The compact frame and moderate stack height suit pick-and-place arms that accelerate frequently. The bidirectional feedback protocol allows the drive to recover the absolute position after a power loss without requiring an additional homing routine, reducing delays when an indexing axis restarts.
Thermal management relies on self-cooling, so no external fan or liquid-cooling circuit is required when adequate ambient airflow is available. The motor attaches to the machine frame through flange mounting, providing a rigid interface for alignment with a gearbox or machine plate. Power and feedback conductors exit through an angled swivel connector that can be rotated to reduce cable stress in confined spaces. A smooth shaft simplifies connection to precision gearheads through a clamping coupling. The unit is supplied without a holding brake, so an external mechanism or drive-applied torque must retain vertical loads while the axis is stationary. It also lacks an oil seal, making external sealing necessary when the shaft is exposed to oil, coolant, dust, or other contaminants.
