General Theory Of Operation - Whirlpool Cabrio WTW8500DW Technical Education

INTRODUCTION
The new Cabrio® Top Load Washer represents industry-leading
innovation with the new improved direct drive system. The
previous direct drive washer operated using a floating basket
to assist in the switching between spin and agitate modes.
NEW COMPONENTS
The washer has the following new components:
Intuitive Touch Controls — the Cabrio® washer features a new capacitive touch console that first asks "what's being washed"
followed by "how you want to wash." First select a cycle from the "What to Wash" (mixed, casuals, whites, delicates, and bulky
sheets) and then select the "How to Wash" (normal, quick, cold, deep water, or color last). This new and improved input will
help the customer achieve the best combination cycle available for the type of items being washed.
What to Wash
Basket — the Cabrio® WTW8500D* washer has an extra
large basket capacity of 5.3 cu.ft. Other than size, the major
difference from the previous model is that this basket does not
have a flotation chamber to assist with changing between spin
and agitate modes.

The new washer operates with a clutch coil system that
provides reliable, immediate, and smooth shifting between
the various wash modes.
How to Wash
Motor — The motor is an electronically commutated direct-
drive 3-phase BPM (Brushless Permanent Magnet) variable
speed design that moves the impeller and spins the basket
without the use of a transmission. The motor is comprised of
a stator and rotor that are attached to the drive assembly. The
motor direction and speed is controlled by the ACU (Appliance
Control Unit) or main control, and is monitored by the rotor
position sensor located on the stator.
