Understanding and Controlling Motors

Driving motors from a microcontroller will be required for a project eventually. This video by NerdKits will go over some of the basics that are needed.

Thanks Humberto.

"Electric motors are a key way of converting electrical power (voltage and current) into mechanical power (torque and speed), and because electric motors are simple and reliable machines, they can be found all over, in many different shapes and sizes. In this video tutorial we’re just going to address the electrical side of the system. This includes some experiments you should try with a DC motor, a model of the system from an electrical perspective, building a MOSFET-based switching circuit, and finally two demos of a microcontroller-operated motor. This video and webpage specifically addresses a brushed DC motor, and although the specifics are not fully applicable to brushless (BLDC) motors, stepper motors, or AC motors, the big ideas about motor modeling and control will be useful in those areas as well."
