“A bunch of things are coming together.” That's how V Sukumar, a senior applications manager for Fairchild Semiconductor, begins a discussion of trends in motor control for the white-goods market.

The ZXBM1021Q20TC (621-ZXBM1021Q20TC) is a single-phase, variable speed, motor control pre-driver featuring built-in Hall amplifier and an integrated current control. It operates up to 18 V with speed ...

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 ...

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 ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

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% ...

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 ...

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 ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...
