Sweeping robots were classified as small household appliances at the beginning of their existence, using the micromotor motors commonly used in fans and blowers. However, compared with the single-direction operation requirements of ordinary micro-motor motors of small household appliances, the sweeping robot faces the needs of loading, forward, backward and different ground scenes. When the general micromotor motor is assembled in the sweeper robot which needs to change the working form flexibly, the failure probability is often higher.
Take the laser sweeping robot as an example. A laser planning sweeper generally has 7 motors, which are respectively applied to the wheel set, rolling brush, side brush, laser head and suction mouth. The common faults of the sweeper after starting can not move forward, spin in circles, roll brush does not turn, laser equipment does not work, etc., may be caused by motor failure, and the problem of any one of them will affect the normal work of the whole sweeper. A good motor, like the "heart" of the sweeping robot, is very important to the sweeping robot!
In the decades since the sweeping robot entered the Chinese market, manufacturers have paid great attention to the upgrading of algorithms and sensors. For a long time, they have focused on the overcoming of software technical barriers, resulting in the neglect of the core hardware motor.
Science language paid attention to the pain point of this industry, took the lead in the launch of a two-year replacement policy for the motor, consumers bought the motor sweeper specially customized for the sweeping robot, since the product purchase date within two years can enjoy free replacement of the motor treatment, which is the first in the sweeping machine industry.
In order to solve the "hidden danger of the heart" of the sweeping robot, Keyu joined hands with the leading figures in the field of micromotors, invested a lot of manpower and material resources, and carried out a special research project of "special motor for sweeping robot". The forward research and development mode based on consumer demand and product use scenario demand is adopted to realize the customization of the sweeping robot motor, so that the sweeping robot motor can achieve higher life and better performance. It is reported that this motor officially realized mass production in December 2018, and has been first used in the small black box and other products.
The robot's special motor is named "FLEX Hummingbird ™". The FLEX Hummingbird ™ motor has the following optimizations compared to the motors of regular sweeper robots.
First, they live longer. The FLEX Hummingbird ™ motor has a lifetime of more than 1,500 hours at full load, three times longer than a typical sweeping robot's micromotor motor, which has a lifetime of about 500 hours at full load.
Second, the failure rate is lower. After continuous testing and adjustment of materials and structure, the research and development team has improved the defects of ordinary sweeping robot motor, which is easy to produce carbon powder accumulation due to friction during operation, resulting in short circuit, burn out motor and even power supply, greatly reducing the failure rate and reducing noise at the same time.
Third, better waterproof and dustproof performance. The FLEX Hummingbird ™ motor has been optimized to meet international IP65 standards to prevent external contaminants from entering, even with high-pressure water spraying.
In the eyes of the industry, the emergence of FLEX Hummingbird ™ motor fills the current domestic blank in the field of micromotors for sweeping robots, and the "two-year motor replacement" policy sets a new benchmark for the industry. As consumers commented, with good after-sales protection, it is more assured to use.
