8ECM0003.1111C-0
The 8ECM0003.1111C-0 cable from B & R Automation is a premium offering in the CM16 Motor Cables series designed for demanding industrial automation environments. This robust motor cable supports a rated speed of 3000 rpm and a rated torque of 3 Nm, delivering precise power transmission for continuous operation. With a torque constant (kt) of 0.955 Nm/A and a voltage constant (ke) of 79.5 V/1000rpm, it ensures efficient energy conversion under varying load conditions. The cable is engineered for high-voltage applications up to 1000 V AC and carries a rated power of 1.07 kW, making it suitable for directly powering medium-size motors. At a weight of 2.7 kg, it balances manageability with the durability needed for factory-floor installations.
Featuring advanced technical capabilities, this cable incorporates a multiturn absolute encoder interface for precise position feedback and synchronization in closed-loop drive systems. It handles a maximum current of 10.2 A with a continuous rated current of 3.4 A, ensuring reliable performance under peak and standby conditions. The cable’s rotor inertia of 0.49 x 10^-4 kgm^2 contributes to stable dynamic behavior in high-precision motion control. With a protection class of IP65, it resists dust ingress and water jets, while its flame resistance rating FT1 and UL recognition certify safe operation in North American installations. EMI performance is optimized by tinned copper braiding shielding with >85% coverage and an additional foil shield, delivering superior suppression of electrical noise.
Operational features focus on durability and ease of use. The cable’s polypropylene insulation provides excellent chemical resistance and mechanical strength, protecting conductors from industrial oils and solvents. A minimum bend radius of 38 mm ensures flexibility without compromising conductor integrity, simplifying routing in confined spaces. The stranded conductor design with filler elements maintains shape stability and enhances crush resistance, while the TPU outer jacket offers abrasion resistance and long-term mechanical protection. At 2.7 kg, the cable remains manageable during installation and servicing, and its connector design supports moderate reuse for occasional disconnections.
Integration into existing systems is seamless thanks to standardized conductor color coding (black, brown, blue, yellow) that complies with wiring standards and accelerates commissioning. The cable interfaces directly with CM16 drive modules and most servo inverters, enabling quick plug-and-play integration. Its robust shielding and high-voltage rating make it ideal for applications in machine tools, packaging lines, and robotic systems where EMI immunity and reliability are critical. Engineers will appreciate the cable’s balance of electrical performance, mechanical durability, and straightforward installation in demanding industrial automation settings.
