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 ...

These variable speed drives (VSDs) were developed to avoid the additional equipment and maintenance requirements associated ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can ...

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 ...

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 ...

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 Ultratech™ variable-speed motor is a four-wire electronically commutated motor with two-way communication. The motor receives commands from the furnace system control board, executes the command, ...

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 ...

What is a variable frequency drive? Heating, ventilation, and air conditioning systems' air supply used to be constant volume into a space. Now a variable air volume control is being used to provide ...
