Inverters:

Inverter or AC drive is a device that can be used to control the speed of a three-phase AC motor without reducing the power and torque of the motor.

Types of inverters in terms of input:

Inverters are classified into three-phase and single-phase categories in terms of input. Of course, their outputs are all three phases.

What are the types of inverters in terms of application?

In terms of applications, inverters are divided into different categories. Inverters are used to start pumps, fans, elevators, cranes, conveyors, extruders, etc. Variable torque inverters are used for pumps and fans, constant torque inverters are used for elevators, conveyors, and cranes, and PG feedback inverters are used for extruders.

### Advantages and uses of inverter:

Engine speed regulator (speed control)
Changer of direction away easily and without the need of a contactor
Turning on and off the engine without the need to disconnect and connect the main power
Reducing mechanical shocks and thus increasing the useful life of the mechanical part
Protecting the motor against voltage increase and preventing damage to the motor
Soft launch without any shocks
Motor protection against overload



In general, inverters are used in three areas:

Constant torque activities such as mixers, extruders
Constant power activities such as traction and mechanical devices
Variable torque activities such as fans and pumps
