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 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 ...

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 Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

After only a few years of being completely immersed in the culture of motor drivers, it is very easy for me to take for granted the fact that most people are not familiar with electromechanical ...

DC Motor Applications provides a comprehensive overview of DC motors and their uses in industry. DC motors generally consist of an armature, a commutator, brushes, and field windings. DC motors may be ...

The tips and tricks when testing motor-driver ICs on the lab bench can help engineers reduce time spent on evaluating and prototyping motor systems. The first installment of this two-part article ...

One of the great things about the Gearing Up challenge of the 2023 Hackaday Prize is that it lets you discover tools that you don’t encounter every day. We had never given much thought to spin coaters ...

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...
