eddy current coupling

[/ˈɛdi ˈkɜrənt ˈkʌplɪŋ/]
nounpl: eddy current couplings
acoplamento por correntes parasitas
1. A mechanical device that transmits torque between two shafts using electromagnetic induction without physical contact, where eddy currents are induced in a conductor when exposed to a changing magnetic field
The eddy current coupling allows smooth power transmission without mechanical wear between the motor and the load.
O acoplamento por correntes parasitas permite a transmissão suave de potência sem desgaste mecânico entre o motor e a carga.
2. A type of electromagnetic coupling commonly used in industrial applications to provide overload protection and vibration damping
Engineers selected an eddy current coupling for the conveyor system to protect against sudden jams.
Os engenheiros selecionaram um acoplamento por correntes parasitas para o sistema de transportador a fim de proteger contra travamentos súbitos.
This is a specialized technical term primarily used in engineering, manufacturing, and industrial contexts in both Brazil and the United States. It is particularly important in Brazilian manufacturing and automotive industries. The device is valued for its ability to provide smooth operation and protection in heavy industrial machinery without requiring physical contact between components.
