2018.02.02. Torque Decoupling of In-out Magnet Coupling

Magnet coupling has two rotors, the driving side and the passive side. Unlike magnetic gears, the driving side and the passive side rotate synchronously. If torque exceeds the allowable torque, connection from the driving side to the passive side will slip, causing torque decoupling. The allowable torque is evaluated with the maximum value of the holding torque that keeps the relative positional relationship between the driving side and the passive side. This document, presents an analysis for finding holding torque and an analysis for transient response during torque decoupling.
