12) Unbalance detecting & laundry balance positioning system
①
Just before the hydrating process and just after reversal rotation for balancing laundry position, this
function is carried out
②
The initial 6 sec is the period of reversal rotation for balancing laundry position , Drum rotates 50rpm
for initial 6 sec
③
Next 12 sec, the rotation increases the speed from 50 rpm to 95 rpm slowly
④
During the next 8 sec, drum rotates at the speed of 95 rpm, the sensor decides the degree of laundry
unbalance with TACHO data which is attached to motor
⑤
If the degree of unbalanced laundry is over 6 times to default value, laundry balancing system carryies
out feed back process 3 times
13) R.P.M control
The rotating motor enables the magnetics( i.e generator) to generate magnetic flux in proportion to r.p.m,
magnetic flux induced by coil sensor in the opposite side produces the wave like the figure below to d
Φ
/dt
and via rectangular wave generating circuit, the waves reaches MICOM and micom controls r.p.m with the
pulse, count and cycle inputted by program.
