The slip clutch [A] consists of the input hub [B] and the output hub [C] which
is the case of the clutch as well. The magnetic ring [D] and the steel spacers
[E] are fitted onto the input hub. The ferrite ring [F] is fitted into the output
hub. Ferrite powder [G] packed between the magnetic ring and the ferrite ring
[F] generates a constant torque due to magnetic force. The input hub and the
output hub slip when the rotational force exceeds the constant torque.
This type slip clutch does not require lubrication.
