Product Description:
B & R Automation manufactures the 8JSA65.EB025D100-0 in its 8JS Synchronous Motors series. The unit is a permanent-magnet synchronous motor used to drive servo axes in packaging machines, pick-and-place stations, and other automated equipment that needs exact velocity and position control. It is mounted by a flange interface that secures the stator housing to machine frames. A keyed shaft transmits torque directly to couplings or pulleys, and the motor is delivered without an oil seal, which suits applications that already provide external contamination barriers.
Under rated conditions, the rotor reaches 2500 RPM, giving process equipment a predictable cycle rate without overspeed. The electromagnetic geometry corresponds to size 6, while an active stack identified as length 5 produces the required torque without enlarging the footprint. Because the housing is self-cooling, waste heat is conducted outward through the stator laminations rather than through an auxiliary fan or coolant circuit. Power and encoder leads exit through an angled connector that swivels to accommodate tight cabinet layouts. The motor is supplied without a holding brake, so vertical axes must rely on external clamps or drive torque for static positioning.
The digital feedback package is based on Inductive EnDat 2.1, which transmits absolute position and diagnostic data to the drive. Resolution is 19/12-bit, and an internal counter records 4096 revolutions, providing true multi-turn information even after power removal. Mechanical position error is limited to ±180 arcsec, enabling fine interpolation for contouring or synchronized line drives. Because the encoder is multi-turn, the axis can resume service without homing after every shutdown, which helps reduce startup delays.
