Employing variable speed motor drives gives an opportunity to have more sophisticated control programs. This enhances the appliance performance and increases overall energy efficiency. Thus home ...

Traditionally, DC motors have been used in precise speed control applications because of their ability to provide acceleration and deceleration from a dead stop position to full speed fairly easily.

As shown in Figure 1, a VFD has three main components: an AC to DC power converter; a DC filter, and a DC to AC pulse-width-modulated inverter that is factory built and tested in an enclosure with ...

Best Electric Machine (BEM), an American innovator in variable-speed electric motor-generator systems, announces the launch ...

TYING IT ALL TOGETHER Dombrowski pointed out that the effectiveness of variable speed does not stand alone, it depends on factors such as the quality of a home’s ductwork. He noted, “There are two ...

IR-SA Integrated Technologies, a collaboration between International Rectifier (IR) and Sanyo Semiconductor, will design, develop, and market variable-speed motor-drive power modules. These ...

Increasingly, manufacturers have migrated to inverterised variable-speed drives for two motor types: three-phase induction and permanent magnet synchronous.

The autoclavable, variable-speed motor controller is designed by Sensitron Semiconductor (Deer Park, NY) to withstand 10,000 autoclave cycles. Outfitted with an overtemperature shutdown protection ...

Motion-control algorithms run in a specialized chip called the IRMCF312, one of IR’s iMotion processors optimized for variable-speed motor control. About the Author ...
