Modern motor is no longer simply a mission of separate parts, but to become a comprehensive system, can say the modern motor is the nerve center of the whole mechanical and electrical system. Modern motor can provide energy for the entire electrical system, that is to say, the modern motor is power center; Modern motor also can rise to adjust, balance, control of the mechanical and electrical system.
even many modern motor combines these two functions. So powerful and comprehensive functions of modern motor inevitably put forward higher requirements, these requirements are not only reflected in the design and production of modern motor itself, but also in modern motor to produce a product of economy, application and development.
six major development direction of modern motor
1, the shift from a brush to brushless
in the past, the traditional dc motor using coverage is very high, mainly because of the vast majority of power supply are direct current (dc). And the traditional dc motor has a brush. Is refers to by commutator and brush brush motor with the motor to automatically completed, within the motor commutator and brush. Although there is a motor skilled in production, the corresponding accessories are cheaper, but there are many shortcomings have brush motor.
, for example, replacement program trouble, accessories, high heating rate, short service life, such as severe loss and serious electromagnetic interference. So, despite the brush motor has a lot of advantages, but it still as the change of era has been replaced with the brushless motor. Brushless dc motor is composed of main body of the motor and drive, is a typical mechatronics product. The kinds of brushless motor is very broad, and almost no has all the disadvantages of brush motor, brushless motor wear small, low noise, low interference, to say the brushless motor relative to the brush motor has a big advantage.
2, hyundai motor direct drive
are usually high speed of modern motor, its running speed can reach hundreds or even thousands of revolutions per minute, such a high speed to high speed of transformation is relatively difficult, but there are a lot of applications is such a demand. So, need to provide it with modern motor parts system conversion speed. But such conversion system will inevitably increase the total size of the motor system, and will also affect the accuracy and efficiency of the equipment. At that time, only make the development of modern motor driven to direct drive, to effectively solve the problem.
3, motor speed change
the development of modern industry often need to motor speed, which often need to maintain a very high or very low speed. Requirements of modern motor to speed and direct drive motor are closely related. Motor speed, not only contributes to the realization of direct driving motor, and can improve the accuracy of the working efficiency of the machine and equipment.
4, from the uniform to the control of motor speed change
basic to maintain a traditional motor speed, most of the motor, only the switch machine this a switch. But in practical use and need for motor speed adjustment, and in this process, the frequent switch to the internal parts of the motor will inevitably cause the wear and tear, the controller and power grid also causes a certain impact. Therefore, applying for the motor of the speed regulation system plays a vital role. For example, and the frequency conversion air conditioning is to take the modern control methods. This way makes it comfort is much better than the traditional air conditioning, and the speed control system makes the machine work more efficient, less electricity.
5, the transition from large to miniaturization, micromation
miniaturization and micromation of modern industry more and more need motor, especially the products of the portable, is put forward higher request to motor size. For instance from the first generation of electronic computer to desktop computers to laptops to tablet, mobile phones, change is the people demand for miniaturization and micromation of the motor. But to achieve motor from large to miniaturization, must first to improve the power of accessories, and to ensure that the performance of the basic components and improve the principle of the motor running.
6, intelligent
in today's society, electronic information technology, intelligent system penetrated into every aspect of our lives. Modern motor not only for the entire electrical power system, but also for motor system balance, regulation, and other functions, and in today's society more and more requirements of modern motor has self adaptation, self renewal, and other functions, to develop personalized service for different tasks. And this is the embodiment of the intelligent integrated into the modern electronic systems. The modern motor intelligent also needs all kinds of electronic theory, intelligent sensor, the integrated use of high-performance materials. brushless motor manufacturers
