Benefits of DC Motors and Why They’re Great for Robotics

DC engines are capable of making them a desirable option for robotic drive motors, which is a big consideration. DC engines come in a variety of shapes and sizes; in our blog 4 DC Engines Styles, you will learn about four of the most common types: an overview. A DC motor, simply put, converts direct power into mechanical energy.

This is in contrast to an AC motor, which uses alternating current to power the electric motor. At its most basic level, DC motors are useful in Abb Robotic because they enable the robot to power the battery, which has numerous advantages in a variety of robotic applications, especially mobile and collaborative robots. Any device that can control the direction, speed, or torque of a DC-powered motor is referred to as a DC motor controller.

 

Not to mention that other motors, such as AC synchronous servo motors, which allow for precise control of the robot's motions, are not used in robotics. In reality, these engines' drive electronics are driven by a DC source.

 

To choose your drive engines, you must first build a robot profile that specifies the robot's size, weight, handling speed, working environment, and necessary joint movements. Both of these variables influence the drive motor you choose.

 

DC motors are ideal for robotics because they allow for speed variation and torque, in addition to making mobility easier with batteries.

 

Variable speed: 

A DC motor is advantageous since it can operate at speeds both above and below the rated velocity. A DC motor's speed can be regulated in three ways. Since the engine speed is proportional to the supply voltage, the variety can be varied by varying the supply voltage. Furthermore, since the flow is inversely proportional to the motor speed due to field results, field windings will vary the flow and current accordingly. Finally, with an engine speed inversely proportional to the armature voltage decrease, you can adjust your speed by varying frame voltage and resistance.

 

Torque:

Many people agree that the greatest advantage of DC motors in ABB robotic Applications is their high torque. They can be used to accelerate applications with a high starting torque and to push heavy loads on start positions. They can also torque continuously at a set rpm, with shaft strength varying with velocity. A DC engine has a high starting torque, making it suitable for applications that shift heavy loads, such as wiper systems, as well as industrial automation, such as conveyor systems or material handling equipment. DC engines are suitable for maintaining a constant torque when an application is in use because of their reliable drive power.

 

Seamless Operations:

DC motors have a smooth operation because they operate at a wide range of speeds and have a high degree of controllable strength. DC motors must be able to start and stop quickly in order to satisfy application specifications in certain industries. A DC engine is an excellent choice if you need fast acceleration, the ability to reverse direction and start/stop efficiency.

 

Harmonic-free: 

Nonlinear charges such as rectifiers or magnets create a harmonic voltage or current at several simple device frequencies, which is usually generated by an electrical power system. Harmonics are absent. Harmonic frequencies in the power grid can cause power quality issues, and harmonics in certain AC engines can cause torque pulsations to be reduced. Harmonic issues are not an issue with DC engines.

 

Selecting any motor for the Robot:

Many different criteria must be considered when selecting an electric motor, such as the amount of load a particular motor can bear, the torque needed to move the robot without overloading it, the motor's rotations per minute when loaded, and so on.

 

Since there are so many different types of engines, one should be chosen based on the application. The ground is navigated by robotics with a basic design and motorized wheels. The wheels are often simpler to design and build than tracks or legs. Navigation over walls or low-friction areas is difficult with wheels, for example.

 

The most popular electric motors in such robots are DC motors. The DC engines have a lot of torque and are very powerful. The speed and torque curves of DC engines can be differentiated by applying torque in response to load. The DC motors used in hobby robots usually have voltage ratings of 3, 6, 12, and 24 volts. When the engine is operated at a voltage lower than that specified in the datasheet, internal friction - primarily from the brushes - is not overcome. Furthermore, if a higher voltage than that supported is applied to the motor, the heat will build up and cause harm.

 

Conclusion:

Since DC engines are free of reactive power (which isn't really power but refers to volts and amperes that are out of phase and carry the active power in an electrical device away), the load supply requires no additional energy. DC motors benefit from quick start-up and acceleration, as well as quick reversing and stopping.

 

DC motors, despite being a more expensive choice, have a wide range of capabilities that make the ABB robotic Application a desirable drive engine.
