Motor solutions form the backbone of modern automation systems, catering to a wide range of applications. Each motor type is designed to meet specific requirements, making the choice of motor a crucial factor in the efficiency and success of an automation project. In this guide, we’ll look into five primary motor types, discussing their features, applications, and suitability for various automation scenarios.


AC Motors: Versatility and Efficiency

AC motors, known for converting electrical to mechanical energy, are a staple in automation due to their versatility and efficiency. These motors are particularly favorable due to their ability to distribute alternating current effectively over long distances.

  • Key Features: AC motors are characterized by their quiet operation and capability to handle variable speed control, making them ideal for consistent speed applications.
  • Applications: They are widely used in applications requiring smooth speed control, such as in fans, pumps, blowers, and conveyor systems.
  • Advantages: Their brushless design minimizes friction, enhancing lifespan, and they offer high efficiency with excellent speed-to-torque ratios.


Brushed DC Motors: Cost-Efficiency and High Torque

Brushed DC motors are preferred for their simplicity and high torque capabilities, particularly in applications that require significant power during start-up and stopping.

  • Key Features: These motors are comprised of stators, rotors, brushes, and commutators and are known for their linear torque-speed relationship.
  • Applications: Ideal for industrial settings involving dispensing, packaging, and certain types of robotic applications.
  • Considerations: The main drawback is the wear and tear on brushes, which can lead to maintenance needs, but their lower initial cost often justifies their use in many scenarios.


Brushless DC Motors: Longevity and High Efficiency

As an advancement over brushed motors, brushless DC motors offer increased efficiency and a longer lifespan due to their brushless design.

  • Key Features: These motors are quieter and more efficient, with magnets placed on the internal rotor, eliminating the need for brushes.
  • Applications: Suited for environments with contaminants like dust and oil, making them ideal for hazardous industrial environments.
  • Benefits: Although they have a higher initial cost, their efficiency, reduced heat output, and longevity make them a worthwhile investment.


Geared DC Motors: Compact Power and Torque Management

Geared DC motors, or gear motors, combine standard DC motors with a gear assembly, providing increased torque and controlled speed.

  • Key Features: These motors work in conjunction with gearboxes, offering a high torque-to-size ratio and a smaller footprint.
  • Applications: Their compact size and power make them suitable for applications where space is limited but high torque is required.
  • Advantages: The gear reduction feature allows for precise control over speed and torque, enhancing application flexibility.


Servo Motors: Precision and Feedback Control

Servo motors like the Sigma 5 and Sigma 7 series from Yaskawa stand out for their precision control and feedback capabilities, making them a key component in advanced automation systems.

  • Key Features: Servo motors provide detailed feedback and require a controller for position and velocity control.
  • Applications: They are extensively used in robotics, CNC machinery, metal cutting, and forming, as well as in packaging and conveyor systems.
  • Advantages: Known for their accuracy, reliability, and high torque-to-inertia ratio, servo motors are ideal for applications where precise motion control is essential.
