Types of electric motors that are commonly used today in industry
In the current era of industrialization, electric motors have become an integral part of many different industries. From operating production lines to home appliances, electric motors play a key role in improving efficiency and minimizing operating costs. In order to choose and use electric motors effectively, it is essential to have a good understanding of the common types of electric motors and their characteristics. Let’s find out in detail with RX Tradex about the types of electric motors that are widely used in the industry today.
1. Types of electric motors
Currently, there are many different types of electric motors used in industry, each with its own advantages and disadvantages. Here are some of the most common types of electric motors:
1.1. Brush DC Motor
Brushed DC motors use coils and armatures, which act as a bipolar electromagnet. The current in the coil is continuously reversed by the commutator, creating a rotational movement of the motor. This motor is commonly used in applications that require high torque at low speeds such as in home appliances, electronic toys, and small industrial machinery.
1.2. Brushless DC Motors
Brushless DC motors have a brushless design, which reduces friction and increases service life. This type of motor uses permanent magnets and controllers to create movement. Brushless DC motors are commonly used in applications that require high precision and performance such as computers, medical devices, and automated control systems.
1.3. Brushless AC Motor
Brushless AC motors (Induction motors) use a magnetic field generated in the stator to rotate the rotor. This motor is commonly used in industrial applications such as water pumps, fans, and conveyor systems due to its stability and continuous operation.
1.4. Direct drive motor
Direct drive motors connect directly to the load without the need for mechanical drive components such as gearboxes. This helps to minimize wear and maintenance, while increasing performance. This motor is used in equipment such as washing machines, air compressors, and applications that require high precision.
1.5. Linear motor
Linear motors produce linear motion instead of rotational motion. This type of motor is used in automated conveying systems, CNC machines, and applications that require precise linear motion.
1.6. Servo Motor
Servo motors allow precise control of position, velocity, and acceleration. These include a motor, a position sensor, and a controller. Servo motors are widely used in automation systems, robots, and equipment that requires high precision.
1.7. Stepper motor
Stepper motors move in fixed steps, allowing for precise control of the position. This motor is commonly used in printers, CNC machines, and devices that need precise position control.

2.1. 1-way electric motor
A 1-way electric motor works on the principle of interaction between magnetic field and current. When an electric current flows through the motor’s coils, it generates a magnetic field. This magnetic field interacts with the magnetic field of the permanent magnet, creating a torque force that causes the motor to rotate.
2.2. AC electric motor
AC electric motors operate on the principle of electromagnetic induction. When an alternating current flows through the motor winding, it generates an alternating magnetic field. This alternating magnetic field causes electromagnetic induction in the rotor, which generates an induction current. The induction current interacts with the magnetic field of the stator, creating a torque force that causes the motor to rotate.
AC electric motors are divided into four main types as follows:
Synchronous motor
The synchronous motor works on the principle of magnetic field. The magnetic field is generated in the stator and interacts with the rotor, causing the rotor to rotate at the same speed as the magnetic field. The stator is supplied with alternating current, which generates a rotating magnetic field at a certain frequency. The rotor is excited by a direct current or permanent magnet, which helps the rotor to synchronize with the stator magnetic field. They are used in applications that require fixed speeds such as generators and pumping systems.
Asynchronous motor
Asynchronous motors, also known as induction motors, operate on the principle of electromagnetic induction. When alternating current passes through the stator, it generates a magnetic field. This magnetic field induces an electric current in the guides on the rotor, creating a magnetic force that rotates the rotor. The rotor rotates slower than the magnetic field speed, this difference is called slippage, which helps create torque.
Asynchronous motors are often used in industrial applications due to their simplicity and high durability.
1-phase engine
1-phase motors use a single-phase AC power supply and often have additional capacitors to create the phase offsets required for starting. They are commonly used in small household appliances such as fans, water pumps, and air conditioners.
3-phase engine
The 3-phase motor uses a three-phase AC power supply, which generates a continuous and regular rotating magnetic field, which makes the motor work stably and efficiently. They are widely used in industrial applications due to their ability to provide torque, provide high performance, and are often used in large industrial applications such as compressors, pumps, and drive systems.
