Washing machines with direct drive

In this article, we introduce the reader to the novelty of the world of technology - washing machines with direct drive. Consider their advantages in comparison with other machines, identify the shortcomings of the direct drive of the washing machine.

The principle of operation of washing machines with direct drive

In order to understand what fundamentally differ washing machines with direct drive from traditional, let us recall the device of a conventional washing machine . The electric motor rotates the shaft, and the torque from the shaft to the drum with laundry is transferred by means of belts on which it is suspended. Such a system was called "belt transmission". This system has its drawbacks: the belt wears out and periodically requires replacement; The operation of the system is accompanied by great noise and vibration.

In 2005, LG introduced a completely new type of washing machines, the competitive advantage of which was a direct drive device in washing machines. In them the engine itself is directly put on the axis of the drum, without any belts and other additional parts. This device was called Direct Drive - in our "direct drive". It should be noted that such models of cars are significantly superior in price to their competitors.

What is justified such a high price and the growing popularity of washing machines with direct drive?

Advantages of direct drive

Let's consider the advantages of direct drive of a washing machine:

1. The reliability of the machine has increased due to the reduction in the number of parts that can fail. LG on its machines gives a guarantee of 10 years!
2. Its stability has increased significantly. The work became almost noiseless, and the vibrations also disappeared. All because the failure of the drive belts helped to better balance the internal device of the direct drive of the washing machine.
3. Saving electricity and water. The direct drive of the engine of the washing machine helps it to automatically determine the weight of the laundry, the degree of drum loading and to select automatically the required power of work and the amount of water without overexpending the resources on a half-empty drum.
4. Better washable and less damaged clothing. If in traditional cars clothes are crumpled and tangled, then in washing machines with direct drive this does not happen due to an even distribution of laundry in a carefully balanced drum.
5. Today, washing machines with direct drive are offered not only by LG, but also by Whirlpool, Samsung and some other companies. You can find out such a model by its characteristic designation: a sticker with the inscription "Direct Drive" on the front side of the case.

Disadvantages of direct drive

For objectivity, let's pay attention to the shortcomings of the direct drive of the washing machine:

1. High price. In such a price category, you can choose the machines of the standard device of reliable brands, which have already proven themselves for decades. It's up to you to decide whether to experiment with innovations.
2. The electronic control system is exposed to the risk of voltage drops, i.e. can break down due to a sudden jump in the electrical network. A new such electronics is very expensive.
3. There is a risk of water entering the engine seal. This is no longer a warranty repair case. The engine dies.
4. The load on the bearings is increased, which are installed with a minimum clearance. Because of this, they have to be changed sometimes.

We want to draw your attention to the fact that 100% of objectivity in the analysis of the work of washing machines with direct drive is not yet possible, because their service life has not yet reached the 10-year mark. The quality of work is always checked by the time and quantity of customer feedback. While this model is still a novelty.
