Motor and motor control
A frequency-regulated motor using a drive belt
drives the drum. The motor is situated on a motor
shelf, under the outer drum with a tensioner
device for the drive belt.
The motor control relies on microcomputer
control and controls acceleration, rpm and
retardation of the drum with high precision.
Further, the motor control can supply
simultaneous values that can be used as
warnings for unbalanced loads and to calculate
the weight of the load.
The motor control communicates with the
programme unit through a serial interface.
The motor and motor control is described in
detail in section 30. Motor and motor control.
