Topic: speed contraller (Read 1 time) previous topic - next topic


hey guys,

simple question,

can anybody tell me ,, when exactly we need to use speed contrallers in robots,,

am making a two wheeled robot with cylindrical body,, do i need speed conraller or not?


The main deciding factor is probably related to the current requirements of you intended motors.  Do you have any in mind?
If your system involves lethal voltages/life critical/flamable elements - you probably shouldn't need to ask.
The Arduino != PC.


More like you require a speed controller if the motor is capable of going faster than you require.   If the motor speed is suitable and you want to control its acceleration you will require a speed controller.   If the in-rush current during uncontrolled acceleration (the motor running up to full speed from a stopped condition) is greater than your power source can supply, you will require a speed controller.  If you want to reverse the motor whilst in motion you will require a speed controller.

In fact for any reason other than the most basic system you will find a speed controller a desirable feature
