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 ...

A recent world-wide interest in the environmental friendliness, water consumption, and energy saving particularly impinges on the home appliance area. The actual regulatory standards and ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

Danfoss introduces Vickers VSD solutions for efficient hydraulic systems, reducing energy use and improving machines ...

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 products ...

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 ...

While advanced field-oriented control enables the use of compact permanent-magnet motors, reductions in drive electronics are also possible when a single controller manages dual motors. Appliance ...

Upgrades that included a constant-torque flux-vector variable-speed motor let a pre-1912 vintage stamping press handle modern production duties. The rebuilt press was refurbished with new ac-drive ...

Danfoss Power Solutions has announced the launch of its Vickers by Danfoss variable speed drive (VSD) solutions across Europe ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...
