What Are the Main Applications of Motor?

As an important part, electric motors are widely used in many applications. Many modern industries involve the use of servo motor products, especially the use of high-speed electric motor. In this article, we will introduce the important application areas of electric motor.

1. Electric servo drive field

In occasions requiring speed control and position control, special electric motors are widely used, such as switched reluctance motors, permanent magnet brushless DC motors, stepping motors, permanent magnet AC servo motors, permanent magnet DC motors etc. Some motors have been used in CNC machine tools, industrial electrical automation, automatic production lines, industrial robots, various military and civilian equipments etc. For example, the AC servo motor drive system is applied to the gravure printing machine, which achieves extremely high synchronization and coordination with its high control accuracy, so that this printing equipment has many advantages, such as high degree of automation, high registration accuracy, large printing range, low production cost and energy saving and convenient maintenance etc. In industrial sewing machines, with the extensive use of permanent magnet AC servo motor control systems, brushless DC motor control systems, and hybrid stepping motor control systems, industrial sewing machines are becoming automated, intelligent, compound, integrated, and efficient, and developing rapidly towards the direction of oil-free, high-speed, and direct drive.

2. Information processing field

Nowadays, the information technology and information industry take microelectronics technology as the core, communications and networks as the forerunner, and computers and software as the foundation. A large variety of special motors are used in information products and semiconductor manufacturing equipment supporting the information age, electronic devices including information input, storage, processing, output, transmission and communication equipment such as hard disk drives, optical disk drives, floppy disk drives, printers, fax machines, photocopiers, and mobile phones etc. We know that the information industry is highly valued at home and abroad, and has achieved rapid development. The world's annual demand for special motors in the information field is about 1.5 billion units (sets). Most of these motors are permanent magnet DC motors and brushless DC motors, stepping motors, single-phase induction motors, synchronous motors, linear motors etc.

3. The field of transportation

At present, in high-end cars, in order to control the fuel and improve the comfort of the car and the needs of display device status, 40-50 pieces electric motors are used, while the electric motors on luxury cars can reach more than 80 pieces. The motors for automobile electrical equipment are mainly permanent magnet DC motors, permanent magnet stepping motors, brushless DC motors, etc. As a green transportation tool in the 21st century, electric vehicles are generally valued in many countries. The motors for electric vehicles are mainly high-power permanent magnet brushless DC motors, permanent magnet synchronous motors and switched reluctance motors etc. The development trend of these motors is high efficiency, high output and intelligence. Domestic electric bicycles have developed rapidly in recent years. Electric bicycles are mainly driven by wire-wound disc permanent magnet DC motors and permanent magnet brushless DC motors. In addition, special motors have also been widely used in locomotive driving and ship propulsion, such as linear electric motors.
