FLE MP FC (machines with frequency control)
In machines with frequency control the same motor is used for wash speed,
distribution speed and extraction. The motor is located on a motor mounting
plate, and drives the drum via a belt.
The tension of this drive belt can be altered by moving the entire motor
mounting plate thanks to the mounting slots on one side. The motor has a
thermal cut-out located in its windings. This thermal cut-out signals to the
motor control unit in the event of the motor overheating, i.e. if the
temperature exceeds 130
°
C.
The various motor speeds for normal action, distribution and extraction are
controlled by a microprocessor-based motor control unit (MU1). The control
signal for the motor control unit goes via a speed selector, which the
operator can also use to select specific extraction speeds for low and high
extraction.
The illustration below shows how the motor is positioned. It is connected
using a quick connector, which makes motor replacement easier.
