Product Description:
B & R Automation engineered part number 8I66T400075.0P-000 which emerged from the 8I6 ACOPOS Inverters range as a precision component tailored for industrial drives. The unit’s 75.0 mm diameter delivers a sturdy form factor and secures bearing integration. The +0.000/‑0.013 mm tolerance maintains an exact dimensional control that also minimizes mechanical backlash. Steel alloy construction provides exceptional strength which resists deformation under heavy operational loads.
A 60-62 HRC hardness rating imparts a resilient surface defense to extend maintenance intervals. Surface finish Ra ≤ 0.20 μm achieves a smooth profile that lowers friction in moving assemblies. Further, a roundness ≤ 0.6 μm preserves consistent circularity and promotes uniform rotation. Its cylindricity ≤ 3.0 μm secures stable shaft geometry to enhance seal effectiveness. The straightness ≤ 2.5 μm maintains precise axial alignment, supporting a dependable coupling. Keeping a length tolerance of ±0.5 mm guarantees precise overall dimensions which simplify system integration. A bare‑metal coating exposes untreated steel and enables tailored surface treatments.
The 8I66T400075.0P-000 weighs approximately 2.2 kg to balance mass and stability. Conformance to DIN 6325 signifies strict quality criteria to streamline assurance processes. Through‑hardening heat treatment yields uniform material properties that improve wear performance. Input voltage from 380V to 500V accommodates wide power networks, enhancing installation versatility. A POWERLINK communication card integrates high‑speed data exchange to centralize motion commands. Adjustable clock frequency from 2 to 16 kHz offers configurable switching which balances efficiency with torque ripples. Designed for 150% nominal current over 60 seconds, this inverter module delivers a brief overload capacity. Its peak inrush current at 500 V ± 10 percent controls startup energy transfer and prevents drive tripping.
