Product Description:

The 8YS-K0015R0.019-0 brushless servo motor is manufactured by B & R Automation within the 8YS Servo Motors series. In modern production lines, this motor acts as a direct-drive actuator, translating commands from a digital controller into regulated shaft motion that maintains synchronization with feedback devices. Its design supports continuous cyclic duty, making it suitable for indexing tables, gantry axes, and feed rollers where rapid reversals and accurate stop positions are critical to product quality. Integrated with B & R drive controllers, it delivers precise acceleration profiles that improve throughput.

During operation, the motor draws a nominal current of 4 A, which indicates the thermal load on the windings and helps with breaker sizing. The DC link supplies 640 VDC, enabling high power density while keeping conductor size moderate. Under commanded velocity loops, the rotor reaches 1500 rpm, which is the reference speed for continuous service before field weakening is applied. Mechanical output at that point is characterized by a rated torque of 14.8 Nm, ensuring predictable drive force for tightening, lifting, or feed functions. Transient loads are absorbed by a stall torque capacity of 16.5 Nm, allowing the axis to hold position against external forces without overheating. An enclosure rating of IP65 blocks dust ingress and low-pressure water jets, permitting installation on open machine frames.

Physical dimensions influence the way the torque and speed characteristics described above integrate into a machine. The motor stands 18 cm high, extends 24 cm along the shaft axis, and measures 14 cm across the mounting flange. This compact footprint leaves room for cable loops and cooling air inside tight enclosures while providing enough stator iron to support the magnetic loading associated with continuous duty. The balanced geometry simplifies corner mounting, minimizes overhung load on gearheads, and eases retrofits into existing servo positions.
