Direct current motor, from 24V to 144V
A direct current (DC) motor is a type of electric motor that operates through the use of direct electric current to generate rotary motion. Unlike alternating current (AC) motors, which operate on alternating current, DC motors are powered by a constant electric current that flows in a closed circuit. Here are some essential features and components of DC motors: Induction Coil: The main component of a DC motor is an induction coil, also called an armature. This coil generally consists of a coil of copper wire wrapped around a metal core. When electric current flows through the coil, it creates a magnetic field. Permanent magnet: A permanent magnet is often used in DC motors to create a stable magnetic field. When the induction coil and permanent magnet are placed close to each other, they interact to create a torque (rotational force) that turns the coil. Commutator: The commutator is a rotating component that reverses the direction of electric current in the induction coil as the motor rotates. This keeps the spool rotating continuously in the same direction, creating a continuous rotating motion. Collector: The collector is a conductive device located on the motor rotation shaft, in contact with the brushes. The commutator is responsible for distributing electric current to the induction coil through the brushes. Brushes: Brushes are parts made of conductive material (usually carbon) which are in contact with the collector. They allow the electric current to be transferred from the power supply circuit to the winding of the induction coil. Speed control: The speed of a DC motor can be controlled by adjusting the supply voltage or by using an electronic regulating device to change the electric current. This allows precise regulation of the engine rotation speed.
DC motors are used in a variety of applications, including electric vehicles, industrial equipment, power tools, toys, fans, positioning systems, and many others. They are valued for their ability to provide high torque at low speeds, their ease of speed control, and their reversibility (ability to turn in either direction). However, they require brushes and commutators that can wear out over time and require periodic maintenance.
A brushed direct current (DC) motor, often called simply a "brushed motor" or "brushed motor", is a type of electric motor that operates by using a mechanical switch (or brushes) to reverse the direction of electric current in the winding of the induction coil, which creates a rotating magnetic field that rotates the motor shaft. Here are some important features of brushed motors: Brushed commutator: Brushed motors have brushes made of conductive material (usually carbon) in direct contact with a rotating commutator. Brushes are used to switch (reverse) the direction of electrical current in the rotor coils as the motor rotates. Simplicity of design: Brushed motors are relatively simple to manufacture and maintain due to their simple mechanical design. This often makes them less expensive than other types of engines. Speed control: Brushed motors are easy to control by adjusting the supply voltage or changing the brush geometry. This makes it possible to regulate the rotational speed of the motor relatively simply. High Torque at Low Speed: Brushed motors are capable of delivering high torque at low speed, making them suitable for many applications requiring high starting torque. Brush wear: A major disadvantage of brushed motors is brush wear. Over time, brushes degrade and need to be replaced periodically, requiring regular maintenance. Less efficient than brushless motors: Brushless motors (brushless motors) are generally more energy efficient than brushed motors due to the lack of brush friction. Brushless motors are increasingly used in many applications. Common Applications: Brushed motors are often used in applications such as power tools, toys, household appliances, ventilation systems, remotely operated vehicles, and other applications requiring simple speed control and low cost.

In summary, brushed motors are DC motors that use brushes to switch electrical current in the rotor winding, which generates rotary motion. They are known for their simplicity of design and ease of speed control, but they require periodic maintenance due to wear of the brushes. Brushless motors are increasingly used to replace brushed motors in many applications due to their improved energy efficiency and increased durability.
A brushless motor, also known as a brushless motor or BLDC (Brushless DC Motor), is a type of electric motor that operates without using brushes or a mechanical commutator to reverse the direction of the electric current in the rotor winding. Instead, these motors use control electronics to switch the current in the rotor coils electronically. Here are some important features of brushless motors: Energy Efficiency: Brushless motors are generally more energy efficient than brushed motors due to the lack of brush friction. This means they produce less heat and consume less power for a given power output. Durability: Brushless motors have a longer lifespan than brushed motors because they do not suffer from brush wear. This makes them suitable for applications requiring continuous and reliable operation. Precise Speed and Position Control: Brushless motors are capable of providing precise speed and position control through the use of sensors such as encoders. This makes them suitable for applications where precision is crucial, such as 3D printers, drones and CNC machine tools. Low noise and vibration: Due to their brushless design, these motors tend to produce less noise and vibration than brushed motors, making them suitable for applications where quietness or reduced vibration is important. Less Maintenance: Brushless motors require less maintenance than brushed motors because they do not have brushes to replace periodically. Common Applications: Brushless motors are used in a wide variety of applications, including computer fans, drones, robots, electric vehicles, medical devices, air conditioning systems, remote control toys and many more. 'others. Different Types: There are several types of brushless motors, including permanent magnet brushless motors, variable reluctance brushless motors, and synchronous magnet brushless motors. Each of these types has specific characteristics suitable for different applications.
In summary, brushless motors are an evolution of brushed motors, offering benefits such as energy efficiency, durability, precise control, less noise and vibration, and less maintenance. They are increasingly used in a wide variety of modern applications due to their superior performance and increased reliability.
