Inverter Washing Machine vs Non-Inverter Washing Machine [2021]: Complete Guide

Last Updated on July 27th, 2021 by RefrigeratorPro Team

If you are planning to buy a washing machine, chances are, you have come across inverter washing machines in the market. Don’t worry we will give you complete information on inverter technology so that you can make a decision on your machine purchase.

Inverter Washing Machine vs Non-Inverter Washing Machine

Here is a quick overview of inverter washing machines vs non-inverter machines.

Non-Inverter Washing MachineInverter Washing Machine
Consumes more powerConsumes 30 – 40% less power
Gives decent wash qualityPerforms excellent washing
In conventional top load washing machines, only pulsator rotatesIn some top load inverter machines, both drum and pulsator rotate in opposite direction
Uses conventional motorsUses BLDC motors
Has shorter life spanHas longer lifespan
Produces more vibration and noiseProduces less vibration and noise
Inexpensive as compared to inverter machinesInverter washing machines are more costly
Cost of maintenance and repairs is not very highMaintenance and repair costs can be higher

How Conventional Washing Machine Works?

A washing machine works by moving clothes through water and detergent to loosen dirt and the drum walls act as a washboard.

Regular washing machines come with a drum that is controlled by a fixed speed motor. And fully automatic washing machines have additional sensors to determine the weight of laundry (load).

Hence, as soon as you load the laundry inside a fully automatic washing machine, its sensors detect the load and determine the amount of time and water required. But conventional washing machines have one drawback, that is, there is no mechanism to regulate the speed of the washing machines as per the load.

For example, if you put 5 kg clothes in 8 kg washing machine, it will run at same speed, that is, full speed. Since there is no speed regulation mechanism, the machine ends up using more power than is required. This also leads to more harsh washing since the machine always runs at maximum speed irrespective of weight / volume of clothes.

Sure, you can use the “gentle” setting if you want to wash a 3 kg load on a 7 kg-rated washing machine if you want to save a little bit of energy, but the cleaning performance will not be optimal. This is where inverter washing machines come in.

Advantages of Conventional Washing Machine

  • Conventional machines are inexpensive as compared to inverter washing machines
  • These washing machines are easier to repair, and the cost of repair is also lesser

Disadvantages of Conventional Washing Machine

  • Conventional washing machines end up using more power because there is no mechanism to regulate the motor speed
  • The motors in these machines have moving parts, which means that wear and tear occurs over time, which reduces the lifespan of the motors
  • Most of the regular machine machines use belt-drive motors which uses a belt to attach the motor with the drum. This produces some vibration, which causes more noise

What is Inverter Washing Machine?

One of the major differences between inverter washing machine and regular washing machine is the motor. Inverter washing machine uses inverter motor as compared to brush motors in conventional washing machines.

Warning- technical details ahead. You can skip this para if you are not interested in the working of inverter machines.

Inverter motors are usually BLDC (Brushless DC Electric Motor). No brush means low vibration and noise. On top of this, the speed of the motor is regulated with the help of a control board. This controller converts (inverts) the voltage from AC to DC and ensures that optimum voltage is supplied to the motor for optimum speed regulation of the motor.

Basically, the inverter controls the frequency of electrical current that goes to the motor so that it can operate at variable speeds. Hence, an inverter washing machine can vary the speed of its motor depending on the load of the laundry. This allows the machine to use exact power required without sacrificing the cleaning performance.

Please note that top washing machine brands have improved upon this technology to offer their own names for inverter washing machines. For example, LG’s direct-drive technology uses inverter motor, and the drum is mounted on the engine for effective and low-noise wash.

Advantages of Inverter Washing Machines

  • Inverter washing machines do not have many moving parts. This ensures long life of such motors
  • These machines produce less vibration, which leads to lesser noise
  • Power consumption is lower because of optimum speed regulation
  • Wash quality is good
  • Most inverter motors come with 10-year warranty, which is quite good

Disadvantages of Inverter Washing Machines

  • These washing machines are more expensive than conventional washing machines
  • Repair and maintenance cost can be higher, even though chances of wear and tear are quite less

Inverter Technology in Washing Machine Brands

Most of the international brands have their own versions of inverter tech. Let’s see some of the main ones here.

Inverter Direct Drive Motor

LG’s Inverter Direct Drive Motor uses inverter technology and a belt-less motor which is connected directly to the drum. This mechanism ensures more stability, lower noise, and lower power consumption. We are yet to see similar technology in any other washing machine brand. Hence, if you are wondering which inverter washing machine comes with best tech, then LG washing machine (with direct drive motor) is the answer!

Digital Inverter Motor

Samsung’s Digital Inverter Motor is also a good option if you are looking for inverter washing machines. However, its inverter motor is a belt-drive motor, hence, it may not be at par with LG’s direct drive motor in terms of technology. However, majority of Samsung inverter washing machines customers are satisfied with the performance and durability.

Intellisense Inverter Motor

Whirlpool’s Intellisense Inverter Motor is another inverter technology that is gaining popularity. Just like Samsung, it is a belt drive motor.

Even though LG offers superior motor technology, as far as inverter technology is concerned there is not much difference in the tech used by all the three brands. Hence, if motor is not a concern, then you can go with either of the brands for inverter washing machines.

Conclusion

Inverter washing machine are priced higher than regular washing machines and are newer technology. They bring with them decent benefits, but at a higher cost. If money is not a concern and you are planning to purchase long lasting washing machine, then you should definitely go with inverter washing machines. Else, regular washing machines are a decent cost-effective option if you do not want to spend more.
