This manuscript presents a novel consequent pole hybrid brushless wound rotor synchronous machine (CPH-BLWRSM) topology. Compared to existing BLWRSM, the proposed topology mainly exploits the inherent ...

Advancements in electrical machines have paved the way for their use in diverse industrial applications. Meeting the unique requirements of each application demands continuous research into different ...

From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life ...

The electric motor industry is undergoing a fundamental transformation. As CEO of ECM PCB Stator Tech, I’ve seen firsthand how artificial intelligence and digital manufacturing are reshaping what’s ...

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 ...

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, ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

The increasing importance of energy efficiency has brought electric motor makers to promote a variety of schemes that improve motor performance. Unfortunately the terminology associated with motor ...

Mechanical Dynamics & Analysis (MD&A) recently completed generator field rewind with a rotor slot dovetail repair on a customer’s GE® 650,000 KVA generator field. The work scope was performed at the ...

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 ...
