SAFETY DEVICE FOR MOTOR
I n case of occurring disorder of motor caused
by extreme-high voltage, over-heating, over-
l oad, safety devices (Thermal Protector) of mo-
tor can be operated and cut off the power
sources automatically.
At this case, motor does not run.
However, motor can be operated normally
again about 1 hour later.
PRINCIPLE OF BUBBLE GENERATOR
1) STRUCTURE
( Motor)
PRINCIPLE OF INTAKE & OUTLET OF THE AIR
I NTAKE : ARMATURE moves up, and BELLOWS inhales the air. At the same time, protector B is open and
A is close.
OUTLET: ARMATURE moves down, and BELLOWS exhausts the air. At the same time, protector B is close
and A is open.
2) FUNCTIONAL PRINCIPLE OF TRANS & MAGNET
• The phase of A.C electric power changes to 60 (50) cycle/sec.
• The magnetic pole of trans core is changed by the change of the phase of A.C electric power.
• The core repeats push and pull (3600(3000) times/min) of the armature magnet.
