Why does the sewing machine motor consume a lot of electricity?

The motor is an important part of industrial sewing machines. With the continuous progress of technology, energy saving is the development trend of the motor. In practical applications, the large energy consumption of the motor has a great relationship with our improper use, mainly in the following aspects:

Excessive surplus or changes in production process adjustment make the actual working load of the motor far less than the rated load of the motor, and the operating efficiency is too low.

Due to the imbalance of the single-phase load of the three-phase four-wire low-voltage power supply system, the single-phase voltage of the motor is asymmetrical, and the motor generates negative sequence torque, which increases the loss in the operation of the motor. In addition, the grid voltage is low for a long time, which makes the motor current in normal operation too large, thus increasing the loss. The greater the three-phase voltage asymmetry, the greater the loss.

These motors use class E insulation, are bulky, have poor starting performance, and are inefficient. Although integrated simple motors have been promoted for many years, there are still many places where old and old (obsolete) motors are still in use.

Some units do not maintain the motors and equipment as required and allow them to run for a long time, which makes the motor loss continue to increase.

It can be seen that to reduce the energy consumption of the motor, we must start from the aspects of purchase, use, management, and maintenance, including correct use, selecting the appropriate motor, and paying attention to the usual maintenance.

and maintenance, including correct use, selecting the appropriate motor and paying attention to the usual maintenance.

We recommend industrial sewing machines to choose sewing machines from big brands such as Juki, singer, pfaff, Durkopp Adler, etc., with low maintenance and long service life.

JUKI brand industrial sewing machines are mainly produced in China and Japan and sold to more than 170 countries in the world. The industrial sewing machines of the JUKI brand are ranked first in the world in terms of market share, quality, and variety, which have been recognized by major famous brands in the world's apparel industry. Especially in the market of advanced countries, whether the garments sold are sewn with JUKI brand industrial sewing machines is an important basis for evaluating their quality. If you are interested in JUKI BRAND SEWING MACHINE, we have the most complete models.
