Brushless DC motors are common place in RC Vehicles. They are small, light, fast and can be inexpensive. [Raynerd] wanted a new spindle for his CNC machine and thought that a brushless DC motor would ...

Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Having to choose between brush-type or brushless motors can complicate the selection. Even experienced designers may ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

DC servomotors are DC motors that incorporate encoders and are used with controllers for providing feedback and closed-loop control. Specifically, servomotors provide precise motion and position ...

Continuing on with our series of Hackaday original videos, this week we are presenting a video all about DC motors. DC motors are relatively simple electromechanical devices that turn electrical ...

DC motor drives are the interface between a controller and a DC motor. Their job is to convert speed and direction input from the controller to currents and voltages compatible with the motor. There ...

DC motors may not be the wave of the future, but they certainly have a secure place in today’s workplace (see DC Isn’t Dead). Therefore, it’s worthwhile for electrical professionals to take a look at ...

In 1834, an American blacksmith along with his wife built the first practical DC electric motor, changing how electrical energy could be converted into mechanical motion. Thomas Davenport used a ...
