Product Description:

The 80CM20001.21-01 power cable is produced by B&R Automation within the 8BC ACOPOS Cables series. It is a dedicated motor supply lead that connects ACOPOS servo drives to matched motors, carrying three-phase power and protective earth in automated machinery. By integrating with the motion system, the cable simplifies installation and ensures that electrical energy reaches the motor with predictable impedance and shielding, supporting reliable position, speed, and torque control inside industrial cells. The cable is designed for moving machine sections such as gantries and pick-and-place axes where continuous flexing is required.

At the core of the design is a conductor set of 5 × 0.75 mm², giving five dedicated power lines sized for currents typical of smaller servo motors. The outer diameter measures 8.5 mm, allowing routing through standard energy-chain separators without excessive fill. Each conductor is made from tinned copper stranded wire, which limits oxidation while providing the flexibility needed for tight bend cycles. Loop resistance is limited to 29 Ω/km, so voltage drop stays low across common machine lengths, and an insulation resistance above 200 MΩ/km helps isolate phases even in humid environments. A PUR outer jacket adds abrasion resistance and oil tolerance, while the internal wire insulation uses a special thermoplastic compound that withstands repeated mechanical stress and thermal cycling.

The cable remains functional for at least 3,000,000 flexing cycles and can travel in an energy chain at speeds up to 4 m/s when the moving bend radius is kept to 85 mm or larger. More than 85% braid and foil coverage forms a low-impedance shield that helps limit electromagnetic emission toward nearby feedback lines. A molded 4-pin male connector on the motor side shortens assembly time and helps maintain correct polarity. This combination suits high-speed assembly robots and packaging modules that require dependable motion-cable performance during repeated travel.
