Six development directions, the future of modern motors is here!

Modern motors are no longer a separate part that simply performs tasks, but become a comprehensive system. It can be said that modern motors are the nerve center of the entire electromechanical system. Modern motors can provide energy for the entire electromechanical system, which means that modern motors are the power center; modern motors can also regulate, balance, and control the entire electromechanical system.

Even many modern motors combine these two functions. Such a powerful and comprehensive function will inevitably put forward higher requirements for modern electric motors. These requirements are not only reflected in the design and production of modern electric motors, but also in the economy, applicability and development of products produced by modern electric machines.

Six major development directions of modern motors

1, from brush to brushless

In the past, the coverage of conventional DC motors was very high, mainly because most of the power supply was DC. Traditional DC motors are brushed. The brushed motor refers to a motor that is automatically completed by the cooperation of the commutator and the brush, and the commutator and the brush are mounted inside the motor. Although the brush motor is technically mature in terms of production, the corresponding accessories are relatively inexpensive, but there are many disadvantages in the brush motor.

For example, the procedure of replacing the parts is troublesome, the service life of the parts is short, the heat generation rate is high, the commutation spark is large, the loss is serious, and the electromagnetic interference is serious. Therefore, despite the many advantages of brushed motors, it has gradually been replaced by brushless motors with the times. The brushless DC motor is composed of a motor body and a driver, and is a typical mechatronic product. There are many types of brushless motors, and there are almost no shortcomings of brush motors. Brushless motors have low wear, low noise, and low interference. It can be said that brushless motors have great advantages over brush motors.

2. Direct drive of modern motors

Modern motors are usually operated at high speeds, and their operating speed can reach hundreds or even thousands of revolutions per minute. It is relatively difficult to change the high and low speeds at high operating speeds, but many applications have such a demand. . Therefore, modern motors are required to provide an accessory system for switching speeds. However, such a conversion system will inevitably increase the size of the entire motor system, and will also affect the accuracy and efficiency of the equipment. At this time, only by modern motor drive to direct drive development, can effectively solve this problem.

3, the speed of the motor

The development of modern industry often requires the speed of the motor, which often requires the motor to maintain extremely high or very low speed. The requirement for the speed of modern motors is closely related to the direct drive of the motor. The extremely fast speed of the motor not only helps to achieve direct drive of the motor, but also improves the working efficiency of the motor and the accuracy of the device.

4, from the uniform speed to the speed change

The traditional motor basically maintains a speed, and most of the motors only have one switch of the switching machine. However, in actual application, it is necessary to adjust the speed of the motor. In this process, the frequent switching of the motor inevitably causes the internal parts of the motor to wear, which will also have a certain impact on the controller and the power grid. . Therefore, the use of the speed control function plays a vital role in the entire motor system. For example, modern inverter air conditioners adopt a speed control method. This way makes it much more comfortable than traditional air conditioners, and this speed control system makes the motor work more efficiently and saves power.

5. The transition from large-scale to miniaturization and miniaturization

Modern industry is increasingly requiring miniaturization and miniaturization of motors, especially for portable products that place higher demands on the size of the motor. For example, the transition from the first generation of electronic computers to desktop computers to laptops to iPads and mobile phones reflects the need for miniaturization and miniaturization of motors. However, in order to achieve the transition from large to small, the power of the basic components must be improved, and the performance of the basic components and the principle of motor operation should be improved.

6, intelligent

In today's society, electronic information technology is changing with each passing day, and intelligent systems penetrate into every aspect of our lives. Modern electric motors not only provide power for the entire electromechanical system, but also have functions such as balance and adjustment for the motor system. In today's society, modern motors are increasingly required to have self-adaptation, self-renewal and other functions to form personalized services for different tasks. And this is the embodiment of intelligent integration into modern electronic systems. The modernization of modern motors also requires the comprehensive application of various electronic theories, intelligent sensors, and high-performance materials.
