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 ...

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 ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Motors are driving demand for electricity, accounting for about half of the electricity we consume, according to the Electric Power Research Institute (EPRI). Many of these motors are found throughout ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

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 ...

The MDrive34Plus2 Speed Control combines a motor, driver, and encoder, and includes a programmable digital oscillator for accurate, variable-speed control. The device uses a NEMA-Size-34 brushless ...

Variable Speed Limit (VSL) control represents a dynamic approach to managing roadway traffic, allowing for real-time adjustments to speed limits based on prevailing traffic conditions, safety ...
