Motors play an important role in daily life. You can find motors, especially a China DC motor, in many electronic appliances. Many motor applications include:

  • Security cameras
  • DVD players
  • Fans
  • Washing machines
  • Phones

The most common types of motors are:

  • DC motor
  • Stepper motor
  • Servo motor

With so many factors to consider, many people still find it difficult to select the motor for their project. Here provided is the basic information about the motors. You must select the motor depending on the type of your project. So, it is essential to pay attention to your requirements.

Every project is unique! Understand the type of your project and decide on what motor will be best suited for your project.

DC Motors:

To convert electrical energy to mechanical energy, DC motors are the devices that use the interaction of magnetic fields and conductors. There are two types of DC Motors:

  • Brushed DC Motor
  • Brushless DC Motor

Brushed DC Motor:

Brushed DC motor is the most common type of motor used in several things, such as:

  • Toys
  • Household appliances
  • Computer cooling fans

This is one of the simplest motors to control and construct. They are called brushed motors, as the current there is provided through two stationary metallic brushes. These brushes contact distinct segments on the ring.

When the commutator rotates, brushes contact the next segment and continue to the rotation of the motor.

Advantages of brushed DC motor:

  • They are simple to control
  • They produce high torque at low speeds
  • They are 75%-80% efficient
  • They are reasonable in prices

Brushless DC Motors:

Brushless DC motors are simpler as compared to brushed ones. When the commutation is achieved, the noise of the brushed DC motor is eliminated. This enables the flow of the current to switch silently. This allows the motor to drive silently. These quiet motors applications are:

  • Drones
  • Computer fans
  • Electric vehicles
  • Disk drives
  • High-precision servomechanisms

Advantages of Brushless DC Motor:

  • These are quiet and don’t produce sound as compared to brushed DC motors.
  • These are more efficient as they achieve maximum rotational torque.
  • They have high durability and require less maintenance.

Stepper Motors:

Motors that move in precise, slow, and discrete steps are called stepper motors. With the value of their precise position control, they are found in several applications, such as:

  • Desktop printers
  • Security cameras
  • CNC milling machines.

Advantages OF Stepper Motors:

  • These have precise positioning
  • They have precise speed control
  • They have high torque and maintain position
  • They are easy to control

Servo Motors:

Motors providing precise motion control are called servo motors. A servo motor’s input identifies the difference between the real and desired speed and position. This is because the controller may adjust any deviation from the target position.

Advantaged of Servo Motors:

  • They have high torque characteristics at high speeds.
  • They come in distinct sizes and torque ratings.
  • They are inexpensive.
