Pros and cons of a direct drive motor in a washing machine

Pros and cons of a direct drive motor in a washing machineManufacturers intensively promote the inverter motor and direct drive of the washing machine motor, replicating its indisputable advantages over belt models. But often silent about the flaws of modern machines, considerable risks and large overpayments. We suggest figuring out whether to trust advertising. Our detailed review of the minuses and advantages of timeless aggregates will help in this. And for dessert - the top 5 best direct-drive cars.

The main advantages

The direct drive system is distinguished by the absence of a drive belt. The drum is mounted directly on the shaft, and there is no need for an intermediate link. All this allows the machine to reach new capacities.

  1. The durability of the engine. Inverter motors, unlike induction or collector motors, do not have rubbing parts - brushes, therefore they are more durable and reliable. This is confirmed by the manufacturer’s 10-year engine warranty. True, the warranty period does not apply to other parts.
  2. Noiselessness. Direct transmission perfectly affects the noise level. So, without a belt and brushes, vibration and hum during machine operation are many times lower.
  3. Washing efficiency. The brushless motor is electronically controlled and can stop abruptly, quickly accelerate and rotate in both directions. All this allows you to better wash and squeeze the laundry.
  4. High speed. The above-mentioned ability to abruptly rotate the drum also reduces the overall duration of the wash. Due to the rapid set of revolutions and quick washing, the modes are programmed for express cycles.
  5. Energy efficiency. The fewer elements in the system, the less energy is spent on its functioning, therefore the absence of a belt has a positive effect on the electricity consumed by the machine.

There is another plus - direct-drive cars can “read” the weight of the loaded laundry and control the washing power sufficient for washing.

main advantages of direct drive

The main thing is that there is no need to constantly change a torn belt. Moreover, when reloading the drum or risking imbalance, the system warns with an error, and does not continue to work until the deplorable end. Among the advantages are the reduced dimensions of the washer, as the missing pulley and belt make the machine compact and more convenient to use.

Key Cons

No matter how attracted these advantages, we must not forget about the pitfalls. Having lost sight of them, you can get from a direct transmission only a large overpayment. We are talking about the following omissions of manufacturers.

  • Bearing load. When there is no additional reference point - the drive belt, all the load goes to the bearings and seals. All this leads to rapid wear and the need for regular replacement.
  • Vulnerable motor. With direct drive, the electric motor is located under the tank, and even the smallest leakage of the seals will lead to serious problems. A ten-year guarantee for such damage does not apply, and repairs will be very expensive.
  • Sensitive electronics. The inverter motor is controlled by a complex system of triacs, which sensitively reacts to any voltage surges in the network. And if the stabilizer is not connected to the machine, you can greatly spend money on repairs.

The reason for these shortcomings lies in the ill-conceived design, which was not fully prepared for the removal of the belt. It is likely that in the future manufacturers will fix all the disadvantages. But while expensive, timeless machines are generally very unreliable and easily leak when water leaks.

The mentioned pros and cons are typical for all direct-drive cars, and if the advantages attract more - choose among a wide range of modern models. True, you should not buy the first machine that comes with the “DirectDrive” sticker.Not all equipment is worthy of attention, so first check out the top 5 best washing machines of this type:

The only difference is complete protection against water leaks.
  • Samsung WW70K62E09WDLP. Samsung offers the machine more powerful and more functional. Firstly, the capacity is 7 kg with the possibility of reloading linen at any time during washing. Secondly, high energy efficiency class A +++. Thirdly, an expanded list of modes with a children's program, steam, soaking and an economical cycle. And, of course, the leading Samsung technologies with eco-cleaning, bubble washing, Swirl Drum drum and a 24-hour delayed start.

  • BEKO WDW 85120 B3. The leading feature of this model is the availability of a drying mode of up to 5 kg of laundry. This is a useful addition to 8 kg of capacity, an accelerated spin of 1200 rpm, 16 programs, a delayed start for 24 hours and a ceramic heater type Hi-Tech. But there are several drawbacks: a low energy class (B) and a wide case with a depth of 54 cm.

It should be understood that a direct drive motor is not a defining characteristic when choosing a washing machine. It is better to pay attention to the brand, power, useful functionality and warranty period. Then a timeless transmission will relieve unpleasant surprises and facilitate the operation of the machine.
