As machines and systems become increasingly networked, electromagnetic compatibility (EMC) of component parts is increasingly significant in preventing undesirable currents, which lead to unplanned and expensive plant shutdowns.
Rethinking cable design, LAPP’s innovative zeroCM® technology in ÖLFLEX® SERVO FD zeroCM® allows for improved electromagnetic compatibility (EMC) and simplified, time-saving connections for power chain applications!
INTERFERENCE (EMI)?
Machinery and factory components generate electromagnetic fields, which can induce currents and lead to unintended consequences within devices. This is known as Electromagnetic Interference, usually shortened to EMI.
EMI needs to be considered during the design phase and can be reduced by selecting EMI-optimized products.
CURRENTS IN INDUSTRIAL PLANTS
Undesired currents increasingly occur on the protective earth cables or equipotential bonding cables in industrial plants, especially where frequency converter-controlled motors are used.
Leakage currents are mainly coupled in at three significant points typically in the motor cable, on the motor itself or within the frequency inverter which can cause major problems:
device trips incorrectly
generation on
electric motor
on building fabric
on data quality
RETHINKING CABLE DESIGN WITH
ÖLFLEX® SERVO FD zeroCM®
Achieving 100% electrical symmetry to minimize magnetic and electrical coupling, our new zeroCM® technology is designed to meet all the challenges in industrial applications.
Using innovative stranding technique, ÖLFLEX® SERVO FD zeroCM® leverages on low-capacitance bundle design with opposing protective conductor to prevent interference caused by common mode conversion.
In addition, longer cable lengths can be laid due to the reduction of the EMC load in the frequency inverter.*
