How the IE4 Classification Changes the Motor Market

摘要

If an application requires a motor to operate rarely, users just want the cheapest machine they can buy that will be reliable in that application. IE2 is intended to make sure that motors being supplied into these conditions meet a minimum standard of efficiency. IE4 is something many manufacturers are talking about and fewer are actually delivering. There is a cost premium to these motors, but the market uptake is not being driven by legislation, rather by shear economics. For a small to medium sized electric motor that is running close to capacity for the majority of the time, used in a continuous manufacturing process for example, then the additional investment in terms of purchase cost is quickly outweighed by the energy saving.
