裝載機(jī)在啟動(dòng)時(shí)，電機(jī)的電流會(huì)比額定高5-6倍的，不但會(huì)影響電機(jī)的使用壽命而且消耗較多的電量。系統(tǒng)在設(shè)計(jì)時(shí)在電機(jī)選型上會(huì)留有一定的余量，電機(jī)的速度是固定不變，但在實(shí)際使用過(guò)程中，有時(shí)要以較低或者較高的速度運(yùn)行，因此進(jìn)行變頻改造是非常有必要的。
Shandong loader at startup, the motor current will be 5-6 times higher than nominal, not only will affect the life of the motor and consume more power. System was designed on the motor selection will leave a margin, the speed of the

motor is fixed, but in actual use, sometimes you want to run at a lower or higher speed, frequency transformation is therefore very necessary.

裝載機(jī)變頻器可實(shí)現(xiàn)電機(jī)軟啟動(dòng)、通過(guò)改變?cè)O(shè)備輸入電壓頻率達(dá)到節(jié)能調(diào)速的目的，而且能給設(shè)備提供過(guò)流、過(guò)壓、過(guò)載等保護(hù)功能。
Shandong loader drive motor soft start can be achieved by changing the frequency of the input voltage equipment to achieve the purpose of energy-saving speed, and give the device to provide overcurrent, overvoltage, overload protection.
