Permanent magnet direct drive pulley, energy saving far exceeds that of asynchronous motors

The overall efficiency of the permanent magnet direct drive system can be improved by more than 20%; compared with the asynchronous motor, the permanent magnet direct drive drum can achieve a 5% efficiency advantage, and there is no need for intermediate transmission links, and the transmission chain can achieve a 15% energy saving effect.

Belt conveyors using permanent magnet direct drive systems can significantly improve system efficiency and save a large amount of electrical energy.

The table below uses a dual-drive belt conveyor with a total shaft power of 500kW as an example to calculate energy-saving benefits.

PS:

• The equipment runs according to 330 days/year, 16 hours/day.

• The energy-saving effect of permanent magnet direct drive drum is based on the small number of mechanical transmission links and the good power factor, and the actual energy-saving effect is subject to on-site measurement.
