Future Trend of Brushless Motor Production Line Automation

With the rapid development of the economy, the process of production automation and digitalization continues to accelerate. The problems of low efficiency, low yield rate, and high labor intensity in the current motor manufacturing industry have become increasingly prominent. The production of brushless motors urgently needs to improve the automation of equipment manufacturing technology. Realize intelligent transformation and upgrading. In order to reduce labor costs and improve production efficiency and quality, design ideas should be changed, and modern industrial technologies such as modern digital technology, Internet of Things, big data and industrial robots should be fully utilized to realize digital production and complete brushless motor design, research and development, production and testing. Work, thereby effectively improving the efficiency and quality of brushless motor production.

The automation of motor production lines is a major trend in the development of the manufacturing industry in the future. It can not only effectively improve the production efficiency and management level of enterprises, but also enhance the competitiveness of enterprises, so it has been valued by countries all over the world. The automated production line is composed of a workpiece conveying system and a control system. It combines a group of automatic equipment and auxiliary equipment in accordance with the process sequence to automatically complete all or part of the production process of the product, referred to as the automatic line.

Brushless motor is a very important part in our daily production and life. It is widely used in new energy vehicles, household appliances, medical equipment, industrial and agricultural production, national defense, technology and daily life. The brushless motor is composed of a permanent magnet rotor, a multi-pole winding stator, and a position sensor. According to the change of the rotor position, the position sensor commutates the current of the stator winding in a certain order (that is, detects the position of the rotor magnetic pole relative to the stator winding, and generates a position sensor signal at the determined position, which is processed by the signal conversion circuit To control the power switch circuit, switch the winding current according to a certain logic relationship). The working voltage of the stator winding is provided by the electronic switching circuit controlled by the output of the position sensor.

The winding forms of brushless motors mainly include full-pitch concentrated windings, full-pitch distributed windings, and short-pitch distributed windings. The difference in the winding form will affect the back electromotive force waveform of the motor, and then affect the performance of the motor. Generally speaking, the full-pitch concentrated winding can get a better trapezoidal back EMF waveform, and the short-pitch winding is conducive to weakening the torque ripple.

Ningbo Nide Mechanical Equipment Co., Ltd. not only actively introduces advanced foreign motor manufacturing technologies, but also recreates them on the basis of absorbing these advanced technologies, increases investment in independent research and development, and masters the core technology of motor manufacturing industrial automation.

NIDE brushless motor manufacturing production line design

Before designing the automatic production of the brushless motor manufacturing line, we must first do a good job in the layout design of the production line.

In order to achieve a lean layout, the following points should be considered:

1, Reduce the distance of material transmission;

2, The design of the production line needs to have certain flexibility to adapt to the production mode of multiple varieties and small batches;

3, Rationally utilize the internal building space of the workshop to improve the space utilization rate;

4, Realize the linear flow of the manufacturing process, make the production continuous, and prevent the problem of overlapping;

5, Make reasonable arrangements for production operations to avoid accumulation in the process of material circulation.

During the design process, we comprehensively consider, highlight efficiency optimization, complete tracking and debugging work in a timely manner, formulate maintenance measures, avoid system failures due to design problems, and ensure the safety of operators.
