Product Description:

The 8DI440.DA0220200-1 is a brushless servo motor manufactured by B&R Automation for the 8DI ACOPOS Motors series. Designed for integrated drive-and-motor architectures, it supplies precise rotary motion to packaging, assembly, and material-handling axes inside automated equipment. By housing the feedback device and power stages in a compact frame, the motor simplifies wiring and supports tight control loops needed for high throughput in industrial automation.

This model employs a EnDat 2.2 absolute encoder that communicates position data digitally to the controller, and its feedback device is classified as single-turn functional safety, enabling verified position monitoring within one revolution for SIL-rated machinery. Measurement is based on an inductive operating principle, which resists contamination from oil mist and dust. Resolution reaches 524,288 (19-bit) position values per turn, supporting fine interpolation at the drive, and the rotor can sustain a rated speed of 2200 rpm without derating. Mechanical dimensions follow module size code 4 and module length code 4, while configuration version 1 indicates the initial release. A keyed shaft end provides torque transfer using standard couplings, and the design omits a holding brake, an oil seal, any special shaft option, and an additional POWERLINK connection.

Axial loads up to 2300 N can be applied directly to the shaft, so thrust cylinders or belt tensions stay within safe limits. Directional accuracy is governed by a precision window of ±65 arcseconds, supporting index tables or pick-and-place heads that demand narrow tolerance bands. The housing withstands shocks of ≤2,000 m/s² and vibrations of 200 m/s² radially or 600 m/s² axially during transport and operation. Functional integrity on emergency-stop circuits is maintained through hardwired safety technology, allowing the motor to integrate into safety chains without additional fieldbus nodes.
