Electric machinery starter the 6th part: Frequency conversion driver
[introduction]When using the applied program that does not need to move amain, frequency conversion driver can reduce cost of specific power consumption. The purpose of VFD is to make the speed of the equipment of electric machinery drive and the speed look that want load match. Driver of other alternating current cannot realize this. Why should use electric power drive? When using the applied program that does not need to move amain, frequency conversion driver can reduce cost of specific…
