Taizhou Sewing Machine Upgrade Calls For "New Power"

Taizhou sewing equipment manufacturing enterprises reached more than 1000, plus a large number of individual businesses and related supporting enterprises, a total of more than 3000, with an annual output value of about 20 billion yuan.

Taizhou is the largest garment machinery production and export base in mainland China. The sewing machine in Taizhou has occupied about 70% market share in the world market. The output and market share of the sewing machine and the high-speed sewing machine account for about half of the world market.

At present, China's aircraft manufacturing industry is worried about the lack of excellent aero engines. China's sewing machine industry needs no such worry.

"By setting the parameters through the digital regulator, the motor can realize the positioning, changing direction and speed regulation, while the ordinary clutch motor has only two choices of turning and no turning."

In July 7th, in Taizhou Zhong Bang sewing equipment Technology Co., Ltd., the general manager of the company, Che Jianbo, introduced "joint servo energy saving motor".

"This motor uses the most advanced permanent magnet brushless motor technology, and 3-5 years later, the company can produce 1 million units per year.

The company's goal is to let all Taizhou sewing machines have a new heart.

Che Jianbo said.

Sewing machine upgrade calls for "new power"

"Now, the problem of increasing production costs and recruitment difficulties has been troubling textile and garment enterprises. They are looking for" low efficiency and high efficiency "sewing equipment.

Che Jianbo said, and the most important thing in a sewing machine is the motor.

According to the statistics of China Sewing Association, at present, there are about 10 million clutch motors in China. Because of its characteristic of power failure, 3 hours per day and 200 watts per hour standby time, about 10000000 sets of sewing machines will be wasted more than 2 billion 200 million kilowatts per year.

The demand of the market has enabled the public companies to pay more attention to the heart of the new generation of motors.

In 2008, by chance, we learned that an enterprise in Xikou of Fenghua, Ningbo, developed an energy-saving motor using permanent magnet brushless motor technology, but it was only used in battery cars.

So Che Jianbo rushed to Ningbo immediately.

After investigation, it was learned that the energy saving motor developed by the company was awarded the national invention patent certificate in 2007, and the market sales performance has been poor since it started at the start of the battery car motor.

At the sight of this product, Che Jianbo, who was engaged in sewing machine electrical production for many years, immediately thought of the feasibility of combining it with sewing machine.

"This product conforms to the requirements of energy saving and environmental protection, which is what the market wants and is very promising."

Che Jianbo said.

In June 28, 2008, the two companies formally decided to cooperate with Taizhou.

Energy saving and emission reduction paradigm: energy saving up to 71%

In July 2009, after nearly a year's technical improvement and research and development, the first sewing machine servo energy saving motor was used for sewing machines, and small quantities began to put on the market.

"When the product is launched, the market reflects very well.

At the end of September 2009, at the China International Sewing equipment exhibition, a large customer in India immediately bought two prototypes for trial.

At present, we are providing motors for famous sewing enterprises such as Jack, ZOJE and Shanghai Toyama. "

Che Jianbo said.

According to the introduction, the biggest feature of the motor is obvious energy saving.

"The traditional clutch motor has a standby power of 140 watts, a power outage and a large starting current, and the power outage of the machine has no standby power loss, and the starting current of the motor is small. Compared with the commonly used clutch motors, the power consumption reaches 71%."

Che Jianbo said.

According to the test of the national sewing machine quality supervision and inspection center, the same 400 Watt power is compared to 12 hours on the basis of ordinary sewing machine, starting from 5 seconds, standby 10 seconds. The power consumption of the ordinary motor is 3.37 kwh, and the power consumption of the machine is 0.96 kwh.

"With 12 hours of work a day, the machine saves 2.41 degrees of electricity per day than the clutch motor. With electricity consumption of 1.2 yuan per hour, it can save electricity by 2.89 yuan per day, 75.2 yuan per month, 902.4 yuan per year."

Che Jianbo gave the reporter an account, although its price is two hundred or three hundred yuan more than that of the ordinary motor, but the electricity saved in one year is enough to recover the cost.

It is understood that in June 18th this year, the product has been included in the "Sixth Batch of energy saving and technology oriented catalogue of Zhejiang province".

Motors that can't be copied

"Before, only the United States, Germany and Japan could produce this kind of motor, and the products monopolized by foreign enterprises could sell as high as 1000 yuan."

Che Jianbo said that if he could produce, only five hundred or six hundred yuan would be enough, and the cost would be saved by more than half.

According to the briefing, the state sewing machine fully served energy saving motor with sewing joints has 16 patents for inventions or utility models. Its permanent magnet AC brushless motor technology has national invention patents, and only 2 enterprises in the country own it.

"Our products are partly developed by the Ministry of Aeronautics and Astronautics and military enterprises, and the digital regulator is designed and developed in collaboration with well-known institutions such as Zhejiang University and Ningbo University."

Che Jianbo said.

It is precisely because of the digital regulator that parameters can be precisely controlled to achieve the functions of "orientation, direction change, speed adjustment" and so on.

According to the authority's comparison, the speed of the traditional clutch motor is 3500-4000 R / min, and the speed of the energy saving motor is as high as 6000-6500 rpm.

"Our motor is the most afraid of counterfeiting."

Che Jianbo said that in addition to patent protection, the chip in the digital regulator can not be upgraded even if someone can decode it.

But we can design the procedures and parameters for customers at any time to improve the efficiency.
