Some electric motors are designed for a very specific purpose. These types of motors are used in a steel annealing furnace application where temperatures can reach up to 1400 degrees F. The motors have special alloy shafts and drive large fans. The fans circulate hot gasses within the furnace in order to anneal steel […]
What is VPI? What is dip and bake?
These two terms are often used in the motor repair industry to describe a type of insulation finishing process used on rewound electric motors. When a motor is rewound, it must be processed in some type of varnish in order to hold the windings together. This varnish, also known as resin, helps to bond the […]
