ESP8266 - Motor

This tutorial instructs you how to use ESP8266 and ......... to control ........... . In detail:

Motor Types

There are three sorts of motors that are frequently used with Arduino:

  • Servo motor
  • Stepper motor
  • DC motor

There are two distinct varieties of servo motor: 180° servo motor and 360° servo motor. Generally, when people think of a servo motor, they are usually referring to the 180° type.

A 360° servo motor is comparable to a DC motor, however, it does not require a hardware driver.

180° Servo motor

Characteristics

  • The range of rotation is between 0° and 180°.
  • It can be rotated in both clockwise and counter-clockwise directions.
  • The position of rotation can be adjusted to a particular angle between 0° and 180°.
  • The speed of rotation can be regulated, but not in a smooth manner.
  • No extra hardware driver is needed for control, just an ESP8266 pin.
  • An additional power source is required.
  • Controlling it is straightforward, just use a PWM signal.

Application

  • Can be done using a single servo motor
  • Any application which necessitates the rotation of an angle between 0° and 180° can be accomplished with a single servo motor.

Stepper motor

Characteristics

  • Provided
  • The amount of rotation is not limited.
  • The direction of rotation can be clockwise or counter-clockwise.
  • The position of rotation can be precisely adjusted to any angle.
  • The speed of rotation can be precisely controlled, as well as the acceleration and deacceleration.
  • Additional hardware and power supply are necessary.
  • Controlling the rotation is complex, so those new to it should use the library provided.

Application

  • Automation and robotics
  • Printers, 3D printers, CNCs, X-Y plotters
  • Cocktail Machines

DC motor

Characteristics

  • The amount of rotation is not limited.
  • The direction of rotation can be either clockwise or counter-clockwise.
  • It is very difficult to rotate to a specific angle with precision.
  • It is easy to control the speed, but it is hard to precisely control it to a certain value.
  • A hardware driver is necessary.
  • An extra power supply is also needed.
  • Controlling it is simple, just use a high-voltage PWM signal.

※ NOTE THAT:

  • , which makes it easier to control the position of the motor.
  • To regulate the position of a DC motor, additional hardware is required, known as an encoder, and a closed-loop control method such as PID control must be implemented. This can be challenging for those who are new to the process.
  • Speed control is much simpler, with options such as slow, medium, fast, and very fast, as well as being able to set the speed to a certain percentage of the maximum. However, to control how many revolutions per second, an encoder and a closed-loop control method such as PID control must be used. This is a difficult task for beginners.
  • Fortunately, some DC motors come with an integrated encoder, making it easier to manage the position of the motor.

Application

  • Previously used to manage something that requires a continual rotation, but the speed does not need to be determined. Examples include fans, pumps, RC cars, drills, etc.

※ NOTE THAT:

There are two primary types of DC motors: brushed and brushless. Brushed DC motors are commonly used in DIY projects.

Motor selection guide

When selecting a motor for a project, there are many factors to consider, such as the weight it needs to carry, power supply, and the characteristics of the application:

  • If your project requires rotation between 0° and 180°, look for an appropriate 180° servo motor.
  • If your project requires precise rotation to any position, a stepper motor is the best option.
  • If your project requires continuous rotation without any specific position, a DC motor or 360° servo motor is the ideal choice.
