Have a larger dc brushed motor rated at 12V or higher to control the speed of, then this controller with its 10A rating could well be what you are looking for.
This is a non-reversing controller which means the motor will only run in a single direction.
As with most speed controllers, drawing more than 10A especially if the motor is stalled may damage the controller.
