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 ...

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 ...

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 ...

The SmartFan Stratus variable-frequency drive provides variable-speed control of single- and three-phase fans, motors, and pumps. The microprocessor-based device operates from a 115- or 230-V ...

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 ...

Adjustable-frequency drives have been billed as an energy efficient way to drive three-phase ac induction motors. Nevertheless, designers should understand that motors fed by inverter power experience ...

Stepper motors are increasingly important for positioning tasks in automated systems due to their compact size, cost ...

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.

In this episode of “EC&M Tech Talk,” Randy Barnett, a journeyman electrician, electrical instructor, inspector, author, trainer, and electrical safety expert, first briefly discusses the background of ...
