What is a digital inverter motor in the washing machine?

Digital inverter motors are brushless motors that contain the minimum number of moving parts to function. They are quieter than regular motors because they make use of strong magnets to reduce friction. Moreover, these types of motors do not heat up as quickly as regular motors, which makes them more durable and long-lasting.

This is why using washing machines with digital inverter motors is ideal for use in laundry rooms or other areas of your home where noise levels are a concern.

That being said, all good things come at a cost; therefore, you can expect to pay a bit more for washing machines with digital inverter motors.

Key Takeaways

  • Digital inverter motors use strong magnets to rotate the drum and require less energy to function.
  • These motors do not produce much friction and are quieter than regular washing machine models, making them more convenient to use in the home.
  • The digital inverter technology adjusts the rotational speed of the motor automatically depending on the load in the washer’s drum. This makes sure that the motor doesn’t spin at high speeds all the time or when it’s not needed.

How does the digital inverter motor work in a washing machine?

A digital inverter motor is a type of motor that operates at variable speeds.

It adjusts the speed of the motor depending on the load of laundry inside the drum.

It makes your washer efficient because the motor speeds up or slows down to maintain an optimal level of water and energy consumption.

The digital inverter motor uses a magnetic field to rotate the drum instead of using brushes (in other words, it’s a brushless motor).

This technology minimizes the friction in the motor, thereby reducing energy loss and increasing the motor’s lifespan.

Washing machines with digital inverter motors have magnets arranged in such a way that they create a rotating magnetic field that interacts with the armature (the part of the motor that rotates) to create torque, which then drives the motor.

When it comes to washing machines, digital inverter motors are much more efficient than the traditional AC motors that are used in most machines.

Digital inverter motors are designed to be more energy-efficient, quieter, and longer-lasting than traditional washing machine motors, and they also provide more precise control over the washing process.

Since digital inverter motors are brushless, they have fewer moving parts; therefore, they are quieter and can run for a long time without any issues.

That being said, these motors are typically used in high-end washing machines and can be a bit more expensive than a regular motor.

Benefits of a Digital Inverter Motor

Energy Efficiency

A digital inverter motor consumes only the necessary amount of energy needed to wash clothes.

It adjusts the speed of the motor to match the load, thereby reducing the overall energy consumption.


The lack of brushes in a digital inverter motor reduces friction, thereby not only making it more efficient but also increasing the motor’s lifespan.

On average, a digital inverter motor can last for more than 11 years.

Noise Reduction

The digital inverter motor technology operates quietly compared to traditional motors. It reduces the noise level of the washing machine, thereby making it ideal for apartments or homes with small children.

Better Performance

The digital inverter motor technology allows the washing machine to have better performance, resulting in cleaner clothes.

Cost-Effective in the long run

Although the digital inverter motor is expensive compared to traditional motors, it is a cost-effective investment in the long run.

The energy savings and durability of the motor ensure that you get value for your money.

Reduced Maintenance

Digital inverter motors have fewer moving parts, which means they require less maintenance over time.

This can save you money on repair costs and extend the life of your washing machine.

Precision Control

Digital inverter motors can provide more precise control over the wash cycle, allowing you to choose different speeds and wash modes for specific types of laundry.

Disadvantages of digital inverter washing machines

With all the benefits that a digital inverter motor offers, it does have a few drawbacks.

Here are a few disadvantages of a digital inverter motor in the washing machine.

Higher cost

Inverter washing machines are often more expensive than traditional washing machines due to their advanced technology.

Repair costs and maintenance

While digital inverter washing machines are generally more reliable and durable than traditional models, they still require regular maintenance to ensure optimal performance.

This may involve cleaning filters, checking for leaks, and other tasks that can be time-consuming.

Furthermore, if a repair is needed, it may be more expensive due to the advanced technology used in the motor.


Some inverter washing machines may not be compatible with all types of laundry detergents and may require the use of specific types of detergent to avoid damaging the machine.

Read the specifications and features before deciding to buy a washing machine with an inverter motor.

Do all washing machines have digital inverter motors?

A digital inverter motor is usually installed on higher-end models, and they are expensive as well; therefore, the motor type depends on the model of the washer.

While digital inverter motors are becoming more common in modern washing machines, older models or lower-end models may still use traditional motors.

It’s always a good idea to check the specifications of a particular washing machine model to determine if it has a digital inverter motor or not.

Which brands make washers with inverter technology?

Many popular brands manufacture washing machines with digital inverter motors.

Samsung, LG, Bosch, Whirlpool, Midea, and IFB are just a few examples.

These washing machines are known for their energy efficiency, quiet operation, lesser vibration, durability, precision control, and faster wash cycles.

Some other brands, like Haier, Hitachi, and Sharp, also make washing machines with digital inverter motors; however, they are relatively less popular when compared to Samsung, LG, and Whirlpool.

It is therefore very important to check the technical specifications of the washer before making any decisions about getting one.

Are digital inverter motors in washing machines durable?

Digital inverter motors in washing machines are often more durable than traditional motors because they use a different type of design and technology to power the washer.

Digital inverter motors are brushless, which means that there is less friction and wear-and-tear, resulting in a longer lifespan for the motor.

Because the motor is not working as hard to maintain a constant speed, it is less likely to break down or wear out easily.

What is the difference between a digital inverter and a direct drive washing machine?

The main difference between a digital inverter motor and a direct drive washing machine is in the type of motor they use. Digital inverter washing machines use a brushless motor that is controlled by an electronic drive control system and makes use of strong magnets, while direct drive washing machines have a motor that is directly connected to the drum without belts or pulleys.

Which is better inverter or a non-inverter washing machine?

In general, digital inverter washing machines are considered better than non-inverter washing machines.

This is because digital inverter motors are more energy efficient, quieter, and longer lasting than traditional motors used in non-inverter washing machines.

Additionally, because digital inverter motors are brushless, they produce less noise and vibration, making for a quieter and more comfortable washing experience.

While non-inverter washing machines may be less expensive upfront, the long-term benefits of a digital inverter washing machine in terms of energy efficiency, durability, and quiet operation make it a better investment for most households, especially if you do a lot of laundry or if there are many members in the house.

Final Thoughts

When we weigh the advantages that a digital inverter motor offers against the disadvantages, it far outweighs the latter, making it a highly desirable and efficient choice.

These types of motors offer faster spin speeds and consume less electricity compared to regular ones, resulting in lower energy bills with efficient cleaning.

Additionally, they also provide a range of functions such as variable speed control as per the load, allowing users to customize their washing experience.

Also, the brushless motor has fewer moving parts and makes use of strong magnets, resulting in lower energy bills and making it an ideal choice for anyone who does a lot of laundry.
