Variable speed control of a compressor motor significantly reduces both the peak and average energy consumption. However, since the standards for air conditioners require a reduction in the seasonal ...

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 ...

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 ...

Developed by Farnell element14, the S12ZVML-MINIBRD variable speed motor control kit is based on the Freescale S12 MagniV. It includes both the hardware and software needed to get a variable speed ...

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 ...

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.

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 ...

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 ...
