Sustainability takes many forms from sustainable cities, green buildings, to renewable energies. Renewable energy as full power resources is the target set for many big corporations. Clean-power movement is the priority of green-minded companies nowadays. Solar panel, as one of the renewables, is commonly used around us and solar powered fan is getting popular in the market. In this issue, we will discover the theory and features of DC fans and how it helps improve the overall energy efficiency of the devices.

DC Fan |
| |
|
Motor is the heart of a fan, its design relates to the fan’s performance. Motors are basically classified into AC motors, DC brushed and DC brushless motors. Energy saving, cost-effective, low noise, long life expectancy,

diversified dimension, and high efficiency are factors why DC brushless fans are most commonly used nowadays.
A brushless DC motor is a rotary electrical machine that converts direct current electrical energy into mechanical energy, and forces produced by magnetic fields. DC fans are compatible with other DC devices, customized to system requirements and thus escalate operation efficiency, that which offer higher flexibility compared to AC fans and function best under low pressure and with reduced fan speed, the noise level can be kept at a minimal, and consume at least 50% less power than AC fans.
To reduce environmental load and waste reduction, we focus on “energy efficiency improvement in ZAWARD DC fan. Motor design dominates heavily to the fan’s performance. If the motor is designed smaller, the impeller area could be larger in the same frame size which could increase the airflow. Under the same dissipation performance, ZAWARD DC fan, requires less RPM than other manufacturers’ fan, therefore it works quicker and consumes less power. When the power consumption is reduced, it reduces environmental load.
