3. Product features
3.1 Large air flow and high static pressure
performance is not enough with the conventional fans, so motor with
higher efficiency was developed for all models, realizing higher rotation
speed. At the same time, blades and frame was formed to be most efficient
for large air flow and high static pressure. It is the fate of motor to increase
the vibration when the speed gets higher, but the vibration was suppressed
by reducing the vibration of the motor itself, and increasing the rigidity
of the frame. As a result, new product has increased up to 73% in air
flow and up to 187% of the static pressure compared to the conventional
product. Fig. 3 and Table 2 show the air flow - static pressure characteristics
comparison between each model and the conventional product.

3.2 Low power consumption
keep the copper loss, iron loss, and mechanical loss of the motor to
minimum, and increase the efficiency of the blades to maximum. With
the development of the San Ace GV Type, all these aspects were
reexamined thoroughly, and measures were taken to minimize each
loss. Simulations such as electromagnetic field analysis were utilized
especially for the reduction of motor loss, challenging for optimization
of the magnetic circuit.

of the global warming and reduction of the running cost.
4 years continuously, the difference of the electrical charge between the
conventional product and new product will be approximately 2,300 yen in
rough estimation. If it is possible to replace 10,000 conventional products
with new products, it is calculated to reduce approximately 23 million yen
of electrical charge in 4 years.
