What Is Inverter Technology In Washing Machine: Inverter Washing Machine

When we hear the term ” Inverter Technology In Washing Machine” Or simply ” Inverter Washing Machine,” we assume that, Oh, this washing machine has an inverter in it. It will run on an inverter even when there is no power.

Let me tell you that whatever you are assuming is wrong. So let’s find out What is inverter technology in a washing machine and how it works.

First of all, let me clear this big misconception. The inverter washing machine does not run when there is no power.

What the inverter technology in washing machines does is that it saves power for you. Saving power means low electricity bills, and low electricity bills mean more benefits to you.

Inverter technology would not let you run your washing machine when there is no power. This is a technology to save power by optimizing the motor speed.

What Is Inverter Technology In Washing Machines?

Before I explain what inverter technology is in washing machines, let me briefly explain why we really need inverter technology in washing machines.

Let’s take the example of a car. When more speed is required, you press the accelerator. Right? When you press the accelerator, more fuel goes into the engine.

So ultimately, your car will burn more fuel only when you need more speed and power. Otherwise, it will only consume minimum power.

Inverter Technology

Now let’s talk about a washing machine. In a traditional washing machine, the motor and the drum rotate at a constant speed irrespective of how many clothes you are washing.

Those clothes could have been washed even if the drum is rotating at a much lower speed. But since the motor is rotating at a constant speed irrespective of the load, it’s a waste of power.

What an inverter technology in a washing machine does is that it optimizes the drum rotation speed based on the wash load.

Fewer clothes mean low speed, and more clothes mean high speed. So the amount of power you consume is directly proportional to the amount of cloth you wash.

How Does Inverter Washing Machine Work?

By now, we have understood that inverter technology optimizes the motor or drum rotation speed.

Inverter technology uses a variable-speed motor to optimize the rotation speed so that the motor speed can be varied. This technology uses numerous sensors to detect the load size.

Whenever those sensors detect the load, it gives a signal to the washing machine’s main controller board, and then the controller instructs the motor at what speed it should rotate.

If the sensor detects a huge load, the drum speed will be adjusted accordingly, and the same is applicable when the load is less. So due to this variable speed, power is saved.

Inverter Technology in the washing machine uses a variable frequency drive ( VFD) or brushless motor capable of varying the motor speed based on the wash load.

Typically Inverter technology is available in the front-loading washing machines with direct drive technology( Found in the top-loading washing machines too but only in the top-end models)

We all might know that the motor is directly connected to the drum shaft in the direct-drive technology. There is no belt drive, no pully. That is why there are fewer moving parts.

Due to fewer moving parts, your washing machine will consume less power, and the inverter technology will complement the direct drive to save more power.

What Is Smart Inverter Technology?

Smart inverter technology is a generic term used when inverter technology is used with direct-drive technology. The word ” Smart” means that the machine is smart enough to control the drum speed based on the wash load.

LG is the first company to come up with this offering. In fact, most of the top-end LG washing machines come with smart inverter technology.

Advantages Of Inverter Technology In Washing Machines

  • Reduce power usage
  • Save you from excessive power bill
  • Machine life increases as the motor do not always run at full speed
  • Less vibration as there are fewer moving parts
  • Frequent servicing is not required as you are not putting excessive load on the motor.
  • Machines with inverter technology and direct drive technology produce very low noise.

Disadvantages Of Inverter Technology In Washing Machines

  • A washing machine with inverter technology is very costly
  • The weight of the washing machine is more
  • Servicing cost is very high
  • More maintenance and care are required

Conclusion: Smart Inverter Technology

I hope you got a fair idea about inverter technology in the washing machine and how that works.

It’s a great technology, and more and more washing machines are coming to the market with this technology.

Going forward, you may see this technology in all washing machines.
