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 ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

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 ...

The high-accuracy TachSyn from ServoTek Products Inc. may be used as either a brushless DC tachometer or brushless DC motor commutator for monitoring the rotational speed of brushless industrial DC ...

I am trying to reduce the electrical noise from a 12V 5A brushed dc motor, driven via a pulse width modulator. Much as I would have fun trying various configurations, I would also like to get the ...

Brushed DC motors are widely used in applications ranging from toys to push-button adjustable car seats. Brushed DC motors are inexpensive, easy to drive, and are readily available in all sizes and ...

RECENT advances in the application of single-phase alternating currents to electric traction have given rise to a large volume of literature dealing chiefly with the motors employed. The possibility ...

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 ...

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 ...
