Although the scale of the washing machine industry is stagflation, with the increasing trend of consumption upgrading, with the official implementation of the new national standard, the market puts higher demands on the noise, energy efficiency, cleanliness and vibration of the washing machine. For the washing motor industry, the transformation to DC brushless inverter motors with lower noise, less vibration, higher precision and better energy efficiency is the only way.
The leading brother Welling Motor made it clear that the transformation of DC motors is a top priority, but even so, the current DC motor capacity of Welling is still limited. It is reported that Welling's current DC motor dominated by BLDC accounts for 15% of total sales, and increased by 80% year-on-year. Welling believes that although Welling used to be the leader in the drum string motor market, the demand for the washing machine industry has undergone tremendous changes, and the speed of transforming BLDC DC motors has to be accelerated.
Wolong Motor said that since its commissioning in 2016, Zhangqiu Haier has achieved an annual production capacity of 4 million DC motors and has sold 4 million DC motors.
According to Nideko, Nideco Group has put forward specific requirements for the DC motor transformation of its various companies, and hopes to transform into a DC motor supplier. Therefore, Nedko Washing Motor currently sets 6 million of the 10 million annual production capacity as the DC motor production line.
The relevant technical person in charge of Wolong Motor clearly stated that at present, the capacity of China's washing DC brushless motor is insufficient. Taking Wolong as an example, with the continuous technical transformation, the traditional series of series motor of drums will continue to reduce people, improve efficiency and reduce the amount. In the case of constant production capacity, the structure of DC brushless products should be increased. ratio.
The relevant person in charge of Nedko also said that Nideco will continue to renovate and increase the procurement of DC motors in the future. In the case of the sluggish sales of domestic washing motors in China, DC brushless motors such as BLDC have become the highlights of the industry. The source believes that the largest sales of induction motors have been less than 10% of the total, and three-phase inverter products are gradually being marginalized.
It is worth mentioning that after the DC brushless motor products are produced in a growing proportion, the BLDC and DD motors are still not good for the drum washing machine. At present, Haier and LG continue to cry for the DD direct-drive washing machine, while the remaining washing machine camps including Bosch appliances support BLDC. This also leads to the current situation of the washing motor market is basically inclined to BLDC, after all, Fisher & Paykel and LG's motor factory supply their own DD direct drive motor.
Until now, it is still inconclusive as to who can better out BLDC and DD direct drive. From the mainstream motor companies, BLDC should be the mainstream, but with Haier's influence in the washing machine market, DD direct drive may still have consumption hot spots. In this regard, a washing motor enterprise technology leader said that in response to this embarrassing situation, only "two hands must be hard to both hands" - on the one hand, reserve the supporting technology of DD direct drive motor; on the other hand, step up research and development of a new generation of BLDC The motor is close to the level of the DD motor in terms of noise, and is much better than the DD motor in terms of cost.
For the DC motor DDM used in the pulsator washing machine, the whole industry has agreed that it is the best alternative to the traditional induction motor.
With the continuous increase of DC brushless inverter motors, the control technology of DC motors has also become an important selling point. In the case that the intelligent sensing of the washing machine becomes the selling point of the market, the sensing technology and motor control of the product become the key elements for the development of the intelligent washing machine. A person in charge of a motor company said that some washing machine manufacturers hope to develop their own electronic control boards and integrate a variety of induction technologies, but the electronic control technology of DC motors has been developed in the motor industry. The person judged that in the future, the industry will be bustling because of the differences between motor companies and machine companies in this respect.
In addition to the inevitable trend of DC, the development of washing motors is simple and clear. Taking Welling Motor as an example, Welling introduced that the current washing machine products of Welling are cost-effective, efficient, quiet, intelligent and other advantages and characteristics, which generally fits the current consumer demand in the market. Willing will promote continuous innovation of products and rapid iteration of technology to meet market consumer demand. For the traditional market, it will meet the downstream demand with high cost performance and miniaturization. For the high-end market, it will be super efficient, ultra-quiet and intelligent. Development, this is also in line with the trend of the entire home appliance industry towards intelligent development.
In fact, Welling's research and development direction is extremely targeted, basically representing the development and breakthrough strategy of the entire washing motor. In the era of sluggish low growth, many washing motor companies have a “pessimistic attitude” to 2018. Under this expectation, how to reduce costs while improving product performance through R&D, and how to increase production efficiency through automated production line transformation. And per capita output, how to plan and increase efforts to transform the DC motor production line, has been the industry topic of washing motor - only in this way, in the era of stagflation, increase profit levels, successfully transform and promote the technological innovation of washing machine .
