YYDW
Series low noise, external-rotor and
single-phase induction motors are of
totally enclosed and fan-cooled type. It obtains
the quality of low noise, low vibration and
turning smoothly. Owing to its soft
characteristic, the stepless speed variety of
the motor is available to adapt to the
requirements of system load changes by voltage
modulations. Featuring fixed shaft and external
rotor, the frame of motor can be connected to
impellers directly. It is the most ideal power
source for horizontal double inhaling
centrifugal ventilators of fans, and vertical
roof centrifugal ventilators or fans alike, and
is widely used for various ventilating devices.
