A contractor wants to raise the car speed from 100fpm to 125fpm, it currently has a 12" sheave. What sheave is required? - Diam=12" 12/4=3" 25fpm=3" 100fpm + 25fpm= 12"+3"= 15" sheave A MOV (Metal Oxide Varistor) burns out. You replace it, but cannot read voltage or resistance. What should you do? - Replace it with a larger MOV On a Ward-Leonard circuit the break is set, but the motor is trying to slip through the break. What is the issue? - Suicide Circuit You have an old DC motor and ar...
