Motor Driver Vs. Motor Controller
You are learning a lot of new information that is essentially technical, and you sometimes face conflicting details, because sometimes the subject you are investigating has some room for debate between experts and enthusiasts.
You may have noticed that some websites have used \"motor drives\" and \"Motor controllers\" in their articles and can sometimes be exchanged.
They have \"motors\" in their names, so it must mean they are the same, right?
Not very good.
Indeed, sometimes you can use these two terms alternately depending on the project and usage.
For example, just let a small robot with a brush motor move a little bit, the two hardware can do a good job.
Don\'t let this fact mislead you,
The two devices are actually completely different.
The motion controller is the brain that operates.
With one of them, you have the ability to program the actions of your robot and focus on how your interior works.
An accurate analogy is that the motion controller in the robot is like the CPU in the computer.
It handles input and output and gives you access to the capabilities of robot projects through your computer.
The motion controller can manipulate the small Brush Motor without difficulty.
Disadvantages: due to the inherent state of the motor controller as a microprocessor, it can directly enter the voltage range of the motor is limited.
If your brush motor needs more than 5 V/3.
3 V, it is possible that your motor controller will not be able to adapt to this situation.
So, what does the car driver have to do with the driver?
They are similar to motor controllers because they all make it easy for your brushed motor to move the motor driver, however, there is no logic circuit for the motor controller.
The motor driver cannot achieve programming and more digital functions.
You need a separate microprocessor to handle the problem.
This may be beneficial.
Because the driver does not need to worry about the logic circuit, a higher voltage range can be handled.
If your robot uses a more powerful motor than usual, the motor driver is more likely to handle this situation than the motion controller.
They have a larger chip that can be processed without a microprocessor.
Which one do you buy?
What hardware to get is a good question, which depends to a large extent on what you are trying to accomplish.
Basic motion requirements will make the motor drivers an attractive option because they lack circuits and are cheaper than the motor controllers.
No need for a feature-
Fully loaded with microprocessor, you can easily save money by choosing a motor drive.
However, if you know that your project requires some programming or computerized functionality, motion controllers may be the best option as they come with logic circuits that are already built in.
Think about it, be alert to your project needs.
