Structure



The basic
layout of the powder-type clutch is shown in Figure 1. The primary driver
(input side) and the friven element (output side) are located on aligned
cylinders and separated by a gap filled with magnetic powder. The two
structures are firmly supported by bearings and can turn dependently.
The powder
space is filled with highly magnetized iron powder, with magnetic coils on the
outer rim which achieve fast magnetization.
When the primary driver turns under non-ed conditions, centrifugal force pushes the magnetic power onto the work surface of the primary driver so that the driver and driven components cannot make contact, and friction between the powder and the friver allow transmission of torque. This type of clutch is also a friction clutch which uses magnetic powder as an interface. In addition, if the output side of the unit is fixed in place it can also act as a powder-type brake.
