Electric motors, or electric motors, use electrical energy to generate kinetic energy. These devices are used in many industries, including automotive, robotics, aviation, marine, industrial machinery, and electronic devices. Due to their high efficiency, high speed, high acceleration, low noise and no production of polluting gases, these engines are a suitable alternative to internal combustion engines.
ساختار موتورهای برقی
Electric motors consist of three main parts: the stator part, the rotor part and the feeding system. In the stator, a constant magnetic field is created, where wires with several loops are located. These rings are known as stator windings. In the rotor part, a moving magnetic field is created, which affects the rotor due to the Lorentz effect and makes the rotor move. This movement produces kinetic energy in the device.
انواع موتورهای برقی
Electric motors can be divided into two categories according to the type of current they use: DC motors and AC motors. DC motors operate using direct current (DC) and are often used in devices that require variable speed, such as grinders, pumps, and entertainment equipment. AC motors operate using alternating current (AC) and are often used in devices that require constant speed, such as parts of automobiles, industrial machinery, and home appliances.
عملکرد موتورهای برقی
The performance of electric motors is determined based on Faraday's electric law and Lorentz's law. According to these rules, the motor being electric means the presence of electric and magnetic fields in the device. When electric current passes through the stator windings, an electric field is created, which creates a magnetic field in the stator. Then, the movement of the rotor inside the magnetic field created in the stator causes the generation of electric current in the rotor windings. This electric current again creates a magnetic field in the rotor which interferes with the magnetic field of the stator and causes the rotor to move.
Motors are major consumers of electricity in most factories. The task of an electric motor is to convert electrical energy into mechanical energy. In a three-phase AC motor, the current passes through the motor coils and creates a rotating magnetic field that rotates the motor axis. The engines are designed to perform this task well. The most important and basic option to save on engines is related to their selection and use.
