INTRODUCTION
The Bravos
™
Automatic Washer represents a
new design that differs from the traditional top
load machine. This washer operates without a
transmission, motor coupler, belt, basket drive
tube, or brake assembly.
NEW COMPONENTS
The washer has the following new compo-
nents:
Drive Motor—The drive motor is an electroni-
cally commutated direct drive 3-phase brush
-
less DC design that moves the impeller/agitator
and spin basket without the use of a transmis
-
sion. The motor is comprised of a stator that
is bolted to the base of the washer tub and a
rotor that is attached to the drive shaft. The
motor direction and speed is controlled by the
machine/motor controller, and is monitored by
a rotor position sensor, (RPS), located on the
stator.
Basket—The basket is designed with a tra
-
ditional balance ring at the top and a flotation
chamber at the base. The outside surface of
the basket is punched to allow lint to catch on
the holes during the wash cycle. When the
water drains, the lint will be flushed off and
out the drain.

Basket Hub—The basket hub consists of two
splined components that engage or disengage
based on the position of the basket in the
vertical direction. The outer hub component
is fastened to the bottom of the basket, while
the inner component is attached to the end of
the drive shaft.
