Application characteristics:

Spinning machine is a kind of equipment in textile industry. In operation it would produce lots of cotton fiber and dust, which will accumulate on the equipment and lead to reduction of heat dispersion of the equipment, causing overheat and aging of the equipment; meanwhile, they will be absorbed inside body of workers and may cause long-term bad effect on labor workers. So the spinning machine is added with dust exhaust fan. Application of this method could help greatly reduce cotton fiber and dust in air of the workshop. Adding with AC drive, the dust exhaust fan could reasonably control the air volume, reduce overall power consumption for operation of the equipment. Meanwhile, the soft-start performance of the AC drive would reduce impact to the power grid at the moment when the equipment is started.
