Approximately only 4% of the world's induction motors are controlled by variable speed drives.

Perfected during the 1960s, the loop is essentially the reverse of the speed drive.

Not until they were still farther from the System could the high speed drive be safely used.

Process control and energy conservation are the two primary reasons for using an adjustable speed drive.

The following are process control benefits that might be provided by an adjustable speed drive:

To counteract these tendencies it was necessary to build a very heavy press, frequently with an expensive variable speed drive.

New chip technology that will give a variable speed drive is also being introduced with a replacement control panel.

Single, two-speed or variable speed drives are available on the new Interstore.

Their speed drive is a time distortion apparatus, I'll wager.

Once, the Mother had thought her brilliant, hoped this physicist might find the forgotten secret of the speed drive.
