SPECIFYING A REQUIREMENT

There are times where you would need extra features other than the standard features provided
by the manufacturer. It is unfair to supplier, that customer complains that I want this and not that
after the item is delivered ,As an example , we highlight the case of an electric motor

a) Protection : IP 54 or IP 55 is usually the standard protection.
b ) Insulation : Generally Class F .there are special class for furnance application.as working enviroment is of higher temperature

c) terminal box : for bigger motors of 300 kw .you may need bigger termination to suit to your cable size , do check your cable size before ordering
Or you may ask for special terminal box cover
Or location of the terminal box, left ,right or top

d) bearings : for big pulley diameter application and belt driven, and because of the big pulley is used is heavy ,you may need upgraded bearing to handle to overhung load

Or the installation of the motor does not facilitate easy greasing or maintenance work .you may opt for life lubricated bearings

Most of the cases, Engineers do not take note of these details

So far .we only come across one Engineer from the Fibreboard industry who knows exactly
his requirement .
