Basic Knowledge of Motor

Electric motor is a kind of driving or driven rotating mechanical component. It is a special mechanical device that rotates by absorbing electric energy and is a decisive factor in the development of modern industry. The motor control system is called the motor control system. It is an important conversion technology of electric energy, the foundation of traditional mechanical control and intelligent control technology, and plays an irreplaceable role in automation technology.

The motor is a mechanical device that adjusts the movement and position by electric energy, and is a device that converts electric energy into mechanical energy. Common ones include AC motor, DC motor, linear motor and stepping motor, etc.

Among them, the AC motor is divided into three-phase and single-phase. The structure of DC generator and frequency converter can generate permanent magnetic field to control the speed of the motor. The AC motor can change speed directly in a certain power range and a certain frequency. DC motor has four characteristics: high speed, large load capacity, high power and low noise. It is especially suitable for occasions with high requirements for electrical speed adjustability. Its application range is mainly in medical equipment and metallurgical equipment.

Stepping motor is characterized by low noise, high precision, convenient driving and constant torque output, so it is widely used in printing presses, tape drives and various automatic instruments and equipment.

Linear motor, which can realize linear motion, has components such as coil, magnet and coil lamination, and can be used in a variety of in-situ measurement and measurement systems.

Motor type

Generally speaking, according to different structures and circuits, the current commonly used motors can be divided into DC motors, AC motors, speed regulating motors and variable frequency motors, and the forms of motors can also be divided into permanent magnet motors, AC synchronous motors, asynchronous motors, DC rotor asynchronous motors and other categories.

DC motor: DC motor is composed of stator coil and rotor magnetic ring with magnet around the rotor. The current in the stator coil is the stator current. It has the characteristics of adjustable load, adjustable current, high reliability, and is commonly used in special military weapons, aerospace and electrical equipment, automotive electrical equipment, marine operating machinery and other applications.

AC motor: It is an electric energy conversion device. It transmits AC power from the power station and outputs low-voltage AC power. It is used to drive various power machinery. It is an ideal motor for factories, rural areas, schools, etc. The effect of speed regulation can be achieved by using AC motor, which is characterized by simple operation and convenient installation.

Speed regulating motor: It is a kind of motor that converts AC electric energy into mechanical kinetic energy. It has the characteristics of speed regulation control and high reliability. It is the core of large automatic mechanical equipment

SIVO Electric Motor has been developed with the most advanced technology, which is easy to operate, low noise, high precision, long service life and stable performance. It is widely used in the automobile industry, electronics industry, machinery industry and other fields to promote the development of industry and serve the society.
