濟(jì)南裝載機(jī)http://www.jmkey.cn/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。濟(jì)南裝載機(jī)系統(tǒng)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。
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.

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.
