Industrial fan

The large industrial fan (4-7.3 m) is a common industrial machine used for space ventilation and personnel cooling. It is commonly used in industrial plants, logistics and warehousing, waiting rooms, exhibition halls, stadiums, and supermarkets. Industrial fans can push a large amount of airflow to the ground, forming a certain level of airflow level on the ground, which contributes to the overall air circulation. The benefits are all-round ground coverage and three-dimensional circulation of air.

Business background

A、Traditional solution (inverter + reducer + asynchronous motor)
1. Asynchronous motors are bulky and inefficient.
2. plus the reducer system is more cumbersome.
3. equipment installation and maintenance are more complicated, the entire system costs.
B、Direct drive solution (inverter + multi-pole permanent magnet synchronous motor)
1. Synchronous motor has high efficiency and the system is more energy-saving and environmentally friendly.
2. Eliminate the reducer, so that the weight and volume of the whole system are reduced, which is convenient for equipment maintenance and installation.
3. the same load current is smaller, the energy saving rate is higher
