What is an inverter for a conveyor? Uses and benefits of use
An inverter is a device that converts alternating current at one frequency into alternating current at another frequency that can be adjusted.
Currently, the use of motors, motors and electric motors in the working process becomes necessary. However, we will need different production speeds, to meet the working needs of the production process.
For large-capacity 3-phase asynchronous motors, it will be difficult to control without an inverter system. That is why we need to use an inverter to allow changing the speed of electric motors, fans or motors accordingly.
Today, inverter is a fairly common device in electrical and automation systems, especially necessary in conveyor systems. This article will help us learn about the uses of inverters and their benefits when used for conveyors.
An inverter is a device that converts alternating current at one frequency into alternating current at another frequency that can be adjusted. Inverters often use semiconductor components to sequentially switch the windings of the motor to generate a rotating magnetic field that rotates the rotor.

There are many types of inverters such as: AC inverter, DC inverter; 220V single-phase inverter, 220V 3-phase inverter, 380V 3-phase inverter, 660V 3-phase inverter, medium voltage inverter... If divided by power source evenly, we can classify inverters into 2 basic types is an inverter for 1-phase motors and an inverter for 3-phase motors. 3-phase inverters are more commonly used.
In addition to versatile inverter products, there are also specialized inverters for pumps, fan inverters, elevators, air conditioners...
Inverter is used to change the frequency of the winding current in the motor of electrical equipment, from which it is possible to control the motor speed steplessly, without the use of mechanical gearboxes.
The inverter rotates the motor by using semiconductor components to sequentially switch off the current applied to the motor windings to generate a rotating magnetic field that rotates the motor.
Conveyor belts are widely used in many stages of the mining process, often in demanding conditions, with common problems being that the conveyor belt can stretch, slip or break. Conveyor belts that operate continuously will wear out, become less reliable, and possibly fail. For industries that require a high level of continuity in production, a failure on the conveyor belt will cause significant damage.
Conveyor inverters help protect conveyors and mechanical equipment by precisely controlling motor speed and torque, prolonging conveyor uptime, and reducing operating and maintenance costs. At the same time, if a joint of the conveyor belt needs repair, the inverter will control the conveyor to move into the correct position for easy repair.
- Conveyor drive system has a very large starting torque. The inverter can generate high starting torque but still ensure the starting current within the allowable limit of the grid. Gentle starting and stopping is achieved by controlling the amount of time required for acceleration/deceleration.
- Allows to adjust the conveyor speed in accordance with the requirements of the production process.
- Energy is saved when running the motor at a speed that matches the load's requirements, and the motor's power factor is high. Moreover, in the case of conveyor belts with inertial running (downhill), the conveyor's mechanical energy can be converted into electrical energy to return to the grid with a regenerative braking inverter.
- When multiple motors are used, the speed can be synchronized and the load can be shared between the motors.
- Can compensate for speed slip, over-torque detection, speed detection plus the function of increasing motor torque when the load torque increases to help the conveyor speed always be stable
- Precise start and stop control on the conveyor system
Inverters are widely used today, especially in the manufacturing and construction industries. Take a look at the benefits that inverters bring:
When starting the engine directly from the grid, the problem of shock and mechanical wear is out of control. The inverter helps to start the engine smoothly, even though the process of starting and stopping the engine takes place continuously, minimizing mechanical wear.
When starting directly, the starting current is many times larger than the rated current, causing the power consumption to skyrocket. The inverter not only helps to start smoothly, but also makes the starting current lower than the rated current, saving electricity at this time. At the same time, do not cause voltage drop (even damage) to other electrical equipment in the same system.
For many applications, such as textiles, dyeing, plastics, etc., the use of inverters will increase productivity compared to using direct power, eliminating some cumbersome and inefficient accessories such as pulleys. , turtle motor (auxiliary motor)…
For applications that need speed synchronization, such as paper, textile, plastic packaging, printing, steel, ... or applications that need to control flow or pressure, such as water industry, compressed air ... or applications such as cranes shafts, elevators... The use of inverters is inevitable, meeting technology requirements and improving productivity.
Nowadays, inverters become common in machine systems, especially in conveyor systems. The benefits that inverters bring to you are much more than the cost you pay, so don't hesitate to invest in an inverter for your drive systems that can be used with inverters. It is a sound investment, an overall and long-term investment strategy.
