For example an 80°C rise is often referred to as a Class B as 80°C is the maximum allowable temperature rise for a 1 0 S F motor with Class B insulation and a 40°C ambient temperature This practice means that a motor with Class F insulation and an 80°C rise is referred to as an F B motor

If a motor is subjected to an ambient temperature higher than 40 o C it must normally be de-rated or a higher insulation class of material used Note motors are typically rated for class B or F insulation Tip specify a class F insulation but a class B

Example a motor operating at 180°C will have an estimated life of only 300 hours with Class A insulation 1800 hours with Class B insulation 8500 hours with Class F insulation tens of thousands of hours with Class H insulation Temperature Tolerance Class B is the most common insulation class used on most 60 cycle US motors

Alternatively the motor could be specified for an insulation class but be design to run at a low class for example insulation class F temperature rise B The advantage of the second method is that there is an inherent 25 o C safety margin - useful if you are in a region with high ambient temperatures or need to date the motor for some

Class B Class B insulation consists of materials or combinations of materials such as mica glass fibre asbestos etc with suitable bonding impregnating or coating substances beware a few older applications used asbestos Other materials or combination of materials not necessarily inorganic may be included in this class if by experience or tests they can be shown to be capable of

Each insulation class has a margin allowed to compensate for the motor s hot spot The hot-spot is a point at the center of the motor s windings where the temperature is higher As can be seen from the above table hot-spot over temperature allowance for A B F …
