tor shelf, under the outer drum with a tensioner
device for the drive belt.
The motor control relies on microcomputer con-
trol and controls acceleration, rpm and retarda-
tion of the drum with high precision. Further, the
motor control can supply simultaneous values
that can be used as warnings for unbalanced

The motor control communicates with the pro-
gramme unit through a serial interface.
