濟南裝載機http://www.casiohk.cn/在啟動時，電機的電流會比額定高5-6倍的，不但會影響電機的使用壽命而且消耗較多的電量。濟南裝載機系統設計時在電機選型上會留有一定的余量，電機的速度是固定不變，但在實際使用過程中，有時要以較低或者較高的速度運行，因此進行變頻改造是非常有必要的。
Jinan 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. Jinan loader system design 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, and therefore frequency transformation is very necessary.

濟南裝載機http://www.casiohk.cn/變頻器可實現電機軟啟動、通過改變設備輸入電壓頻率達到節能調速的目的，而且能給設備提供過流、過壓、過載等保護功能。
Jinan 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.
