Robotics involves several different concepts, but five in major. These are generally- mechanical, software, electrical, electronics, and architecture. Now, amongst all these, the driving force of a robot is motor. You can still build a robot without software, and that will be manually operated. However, no robot can even move a bit without having a motor system.
First, these servo motors are used to facilitate motion in multiple directions at joints and other vital parts of a robotic chassis. Second, engines are known for delivering power measured in watts, which enables the robotic frame to work. Be it a standard robotic car or an arm, no such structure can be successfully created without the implementation of a servo motor.
Now, with the introduction of the mini motors, implementing this electromechanical component has become more comfortable and hassle-free. However, as these motors are pretty much new to the market, confusions can arise while choosing the most appropriate one.
So, let’s first learn how to choose the most suitable mini motor for your project, then you can move onto deciding why you need one.
Torque is the force with which a body can be moved about its perpendicular axis in the direction of the applied reasonable force component. This means that torque symbolizes to which extent a force applied perpendicularly on the surface can rotate the body about its line of action.
While considering mini motors, make sure you are choosing one which can nearly satisfy your torque requirement. Obviously, you need to calculate how much torque you need and then you can look for the suitable motor.
Rated Speed Of The Rotations
Now, every motor, be it DC, brushless DC, or servomotors- each of them is associated with a rated speed limit. This signifies the number of revolutions done by the rotor in a minute. Calculate how much speed you need and always buy the motor with a speed limit higher than what you need. This will keep your motor safe even if you are operating it at its maximum speed.
The Power Output Of The Motor
The next thing that you will have to keep in mind is power output. Obviously, this should be the rated output so that you can safely operate the motor without having to worry about it becoming obsolete.
The motor should be capable of delivering the power that you need to run your project. For this, you have to be very precise about how much outage you need in terms of mechanical energy. Rozum is a mini motor dealer who houses some of the best motors- both with low and high power outputs. You can always get in contact with them to have the most appropriate motor for your project.
Direction Of Motion
The next thing which will matter is in which directions the mini motors are rotating. As per your direction requirement, the type of motor will vary and hence, be very careful while choosing the motors.
Amount Of Load To Be Lifted
The output power is also associated with the amount of weight you need to handle. If your robot needs to handle a capacity of 5kg, then the motor should be able to deliver mechanical power equivalent to 5kg of weight. In the absence of any mechanical load, the motor should be able to handle the electrical load.
