installation of the MV drive can lead to a significant savings on
energy cost. It was reported that the use of the variable-speed MV drive
resulted in a payback time of the investment from one to two and a half
years [7]. The use of the MV drive can also increase productivity in some
applications. A case was reported from a cement plant where the speed of
a large fan was made adjustable by an MV drive. The collected dust
on the fan blades operated at a fixed speed had to be cleaned regularly,
leading to a significant downtime per year for maintenance. With variable-speed
operation, the blades only had to be cleaned at the standstill of the production
once a year. The increase in productivity together with the energy savings
resulted in a payback time of theclose.

The Rams’ strange, blind loyalty to Jeff Fisher had to end, and it finally did. None of Fisher’s five Rams teams finished .500 or better, and none of them ranked higher than No. 23 in the NFL in points scored. He was fired during last season.

Two men will determine if the Rams can actually move the needle in L.A. over the next few years: new coach Sean McVay and quarterback Jared Goff.

He’s young, but he has already drawn praise for his acumen as an offensive coach. With McVay as their offensive coordinator last season, the Redskins finished third in the NFL in yardage and
