1.1 What is an inverter?
1.1.1 Basic functions of the inverter
◎ Inverter
Motors are used to operate many of the devices and products we use on a daily basis.
The reason devices do not suddenly start to operate when power switches are turned on is because the inverter
controls the speed of motors.
In basic terms, the inverter is
a device that changes the speed of standard motors without restriction
.
1.1.2 Benefits of the inverter
1
The inverter can freely changes the speed of standard motors. They can be
also connected to the already-installed standard motors.
2
The inverter can drive standard motors at a set speed regardless the power
supply frequency.
3
The inverter can save energy (electricity).
4
The inverter can improve productivity by changing the standard motor speed
to match the application.
5
The inverter can perform smooth start and stop operations by reducing the
starting current of standard motors.
