Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

When applied to blowers and pumps, variable-frequency drives (VFDs) offer energy savings. In mechanical applications, they allow fine adjustments that wouldn't be possible by other methods. Despite ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

Recent advances in power electronics have driven the evolution of motor drive systems into the high-frequency domain, where precise modelling and analysis are essential. High-frequency modelling ...

Adjustable or variable frequency drives AFDs or VFDs use rectifiers to convert ac powerline electricity into direct current. Then inductor-capacitor filters Adjustable or variable frequency drives — ...

Motor control, particularly frequency-controlled drives, is a technology that has advanced quickly in recent years as a result of the widespread use of motors in a variety of applications and the ...

A new low-voltage platform combines ultra-fast gallium nitride (GaN) switching with intelligent filtering to create ultra-high-frequency motor drives. QPT claims its MicroDyno platform facilitates the ...

The new revolution in power. How GaN-based motor drives can significantly reduce power consumption. Electric motors are one of the biggest consumers of energy, both in business and consumer products.

Flat-rolled steel producer Cleveland-Cliffs Inc. has announced plans to introduce its Motor-Max product line of nonoriented electrical steels (HF NOES) for high-frequency motors and generators in the ...
