Selecting and choosing a drive motor for your robotic device will require research, detailed power requirements analysis, and creating a corresponding robot profile.
Most robotic applications require the robotic device to be mobile, along with its operational ability; therefore, they will need to be powered by a battery source, hence needing a DC motor solution like a stepper motor. And when we talk about a DC motor, we are referring to a DC permanent brush-type motor.
Adjustable voltage and current levels will provide the necessary control via an amplifier, and you have a DC solution system that will provide the motor power for your robotic device.
In simplistic terms, a DC motor will convert electrical energy as provided by the direct current into mechanical energy. Robotic applications expect a high starting torque power capability. The DC motor has a high torque-to-speed ratio, enabling it to provide sufficient high torque speeds with ease and minimal effort – it is this fundamental reason why DC motors are preferable to AC motors for the robotic power source. It also makes them a good choice for security cameras.
As the name implies, AC motors apply alternating current to the electric motor, which is insufficient for the basic mobility and sudden torque actions required by robotic devices. AC motors are used in robotics – there are AC synchronous brushless motors (servo) that enable precise movement control for robotic movements.
What are DC Motors?
A brushed DC motor has a rotor with electromagnets around it. When you apply current to the electromagnets, they repel each other and cause the rotor to spin. The electromagnets and the rotor can become worn out over time, and they require periodic maintenance.
Why DC Motors Are Used in Robotics
DC motors are used in a wide range of applications, including robotics. Robotics is the science and engineering of creating machines that can perform human tasks. It also includes the design and manufacture of computer systems that can simulate human behavior. Robotics is a very versatile field, and it can be applied to a wide range of industries, including healthcare, education, security, and transportation.
Why do you need to use DC motors for your robotics project? DC motors are ideal for robotics applications that require a motor with high torque at low RPMs. They are especially useful for projects that require precise positioning or movement.
There are multiple advantages to using a DC motor for your robotics project. Here are a few of the most important advantages of using a DC motor for robotics applications.
DC motors have high starting torque. This makes them ideal for robotics applications that require significant force to get the motor moving. DC motors have high sustained torque. This makes them ideal for robotics applications that require a constant force. Furthermore, DC motors have a wide range of speed capabilities that make them ideal for robotics applications that require accurate speed control.
Additionally, DC motors can be easily controlled with an embedded computer system. This makes them ideal for robotics applications that require computer control. DC motors also provide a smooth and consistent rotational motion which makes them ideal for robotics applications that require precise motion.
Selecting the Right DC Motor for Robots
Three main factors need to be considered when selecting a DC motor type for any robotics application:
- Motor Speed: both minimum and maximum speed, with acceleration
- Torque: maximum torque that can be generated and its relation to speed
- Precision: of the motor’s operation and its repeatability.
If the budget needs to be contained or is inflexible, then a stepper motor will need to be seriously considered. When performance is a priority for your robotic application, a servo motor will be more suitable but will present a more expensive option.
Regardless of whether a DC motor is used for industrial or personal environments, designing a high-end motor requires accurate positioning capabilities. A versatile and reliable solution is needed to optimally operate any mechanical robotic application.
The scope for the application of DC motors and robotics devices is endless, and such motors have recently been associated with emerging functions such as drone manufacturing and drone flying operations, through to the big Agriculture 4.0 large-scale precision machines.
