With the progress of society and the improvement of people's living standards, home ownership can no longer meet people's requirements for high-quality life, and more and more people are beginning to pursue environmentally friendly, healthy, comfortable and convenient lifestyles. In many families, vacuum cleaners have become a necessary small household appliance for household cleaning. With the development of vacuum cleaner technology, people's attention has continued to increase.
From the perspective of market data, the retail scale of vacuum cleaners has increased year by year. In 2018, the overall scale of the domestic vacuum cleaner market exceeded 23 billion yuan, and the retail volume exceeded 24 million units. As a pioneer in the vacuum cleaner industry, Zhongtianwo focuses on the research and development of core components and motors, and insists on using Technological innovation builds its own core competitiveness, and iteratively upgrades motor technology to establish an important position and brand influence in the field of global environmental cleaning. From the 1980s that broke the situation that China's vacuum cleaner industry had to rely on imports, to today's launch of the world's top-level brushless digital motors, it can be said that the development history of Tianwo is a history of core "core" technological innovation.
In the 1980s, China's home appliance industry entered a period of rapid growth. As an imported new home appliance category, vacuum cleaners were quickly sought after by the domestic market, and the products were in short supply. At that time, most of the vacuum cleaner motors produced in China were micro motors with a speed of less than 3000 rpm, and the failure rate was very high. Vacuum cleaner manufacturers are forced to import only motors, and the development space is squeezed. In the late 1980s, Ni Zugen, who was the technical engineer of Chunhua Vacuum Cleaner Factory at the time, with a lot of research and experimentation, carried out technical breakthroughs from internal processes to parts and components, and solved the problems caused by the burning of domestic motors. Due to the problem of poor reliability, we developed China's first high-speed commutator vacuum cleaner motor with a speed of more than 25,000 rpm, realizing the localization of vacuum cleaner motors for the first time, breaking through the technical gap of domestic motor research and development.
In 1994, Ni Zugen founded Tianwo Electric, and began to engage in the research and development of household vacuum cleaners and ODM export business. Unlike most people who insist on being bigger first and then becoming stronger, Tianwo adheres to the principle of "first be strong in an industry, and then Based on the principle of "can be bigger", Tianwo has only done one thing in the first ten years, that is, to build its core competitiveness around the heart of the vacuum cleaner - the motor.
In the early 1990s, the speed of domestic vacuum cleaner motors was generally 23,000 rpm, and the weight could reach 1.5 kg. It can be said that the weight is large, the volume is large, and the efficiency is low. Tianwo independently developed the first high-performance motor with a speed of more than 30,000 rpm in China, realizing the lightweight, miniaturization and performance of the motor. Under the financial, technological and environmental conditions at the time, this innovation was not easy. Tianwo first started to tackle the problem of paint dripping on the rotor of the motor. Since the high-speed rotation of the motor will generate huge heat, it is easy to cause the rotor to drip paint and cause the machine to burn. Therefore, Tianwo collected paint raw materials all over the world, and the R&D team experimented with various paint materials and processes one by one in the high-temperature aging room. In the end, the epoxy resin paint was successfully matched, and the problem of motor burn-in was finally overcome; The technology and quality of brushes and bearings are tackled, and a series of technical problems such as process precision, quality strength and running balance of core components are solved. After half a year of exploration, research and testing, in 1997, we successfully independently developed China's first high-performance series motor with a speed of 33,000 rpm. The speed is increased by 40%, the weight is reduced by 30%, the efficiency is increased by 20%, and the power reaches 1200 watts. The innovation of this motor has established Tianwo's leading position in the domestic vacuum cleaner industry. Since then, it has also opened the prelude to cooperation with international big brands.
In the next few years, Tianwo continued to carry out technological innovation. On the premise of the continuous reduction of the motor volume, the power continued to increase, and gradually increased to 1400 watts, 1600 watts, 18 million watts, and 2000 watts. At the same time, the motor speed was gradually increased to 43,000 RPM, 45,000 RPM, 50,000 RPM, 60,000 RPM.
With the wave of consumption upgrades, Tianwo began to try the research and development of wireless vacuum cleaners in response to the inconvenient use of traditional wired vacuum cleaners. The wireless vacuum cleaner is limited by the fact that the battery capacity cannot be too large, so higher requirements are placed on the motor efficiency and performance. In order to make the vacuum cleaner smaller, work longer and have more suction, Tianwo Electric began to independently develop high-speed and high-suction brushless digital motors. In the process of research and development, they always insist on originality, form technical differences with other brands, and then build a competitive advantage.
In 2013, after two years of dedicated research and development, the first generation of Tianwo was also the first in China and the second in the world with an 80,000-rpm ultra-high-speed brushless DC digital motor. Technological innovation, 80,000 rpm ultra-high-speed digital motor was awarded the 2014 China Home Appliance Technology Progress Award by the China Household Electrical Appliances Association.
In 2015, Tianwo's second-generation 100,000-rpm 380W brushless digital motor was born. It adopts "three-phase" brushless digital motor technology without Hall, which has higher motor efficiency than "single-phase" technology; the fan adopts high-strength Alloy aluminum, which has higher reliability when the vacuum cleaner is clogged with the suction port to produce ultra-high speed operation. And quickly launched China's first high-suction multi-function wireless vacuum cleaner with three-stage tornado filtering technology and super digital motor - Mojie series, the new motor technology makes Mojie's suction power reach or even exceed 1000W horizontal wired vacuum cleaner The suction power of the whole machine has created 18 invention patents, which completely subverted the concept of traditional vacuum cleaners, and has both lightness and convenience and surging suction power.
In 2017, Tianwo once again upgraded its technology and launched the latest research results - the third-generation 100,000-rpm 450W super brushless digital motor. The suction power has been greatly improved. The suction power is equivalent to that of a 1500W AC vacuum cleaner motor, bringing unprecedented wireless vacuum cleaners. Surging power, suction is nearly 50%-100% higher than the performance level of brushless digital motors in the industry at that time.
In 2019, the motor suction power of Tianwo's latest generation of vacuum cleaners is 160AW, and the efficiency is as high as 55%, which once again breaks the industry's cognition. This "black technology"-style scientific research achievement can be regarded as a new world record and a new benchmark for the industry, and will surely become another business card of "Created in China" that is world-renowned.
