What role wood sanding machine inverter?

Frequency converter in many mechanical devices is the main components of the essential of his main role is also very good understanding, since called frequency converter, then of course is used for frequency conversion, is also changing frequency. You may have a lot of friends is not a speak too understand, what exactly is the purpose of this change frequency? Why need to change the frequency? Actually the ultimate purpose is to change frequency by changing the wood sanding move motor frequency, so as to achieve the goal of energy saving. Because the device at the time of operation is not required for every moment power are the same. For example as we drive, sometimes need to have a larger power, such as hill, sometimes need motivation is not so big, such as relatively flat road and decline, if no matter under what circumstances is to use the same power can cause the waste of energy, so the inverter application in wood sanding machine mainly it is for this purpose.
