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 ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

Variable speed drives that drive three phase motors are ubiquitous components of industrial machines that help save energy and optimize systems. Traditional scalar control techniques for variable ...

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 ...

An introduction to the symmetric, multiphase, wound-rotor “synchronous” doubly-fed motor or generator system, called SYNCHRO-SYM. How SYNCHRO-SYM is only possible with brushless, automatic, ...
