Accordingly,we divide motors into two ranges of induction motors, four types of motors forexplosive atmospheres, frequency controlled motors, most notable of which aresynchronous motors, and special application motors. The last category of motorsinclude, for example, marine motors, brake motors, and smoke extraction motors,which are based on the basic induction motor but have modifications that varyaccording to the purpose of use. Their features are not further described here.1.2.1 Standard induction motorsABB offers two types of low voltage induction motor series: Process performanceand General performance motors. The first are the most commonly chosen inductionmotors for demanding industrial uses and cover frame sizes 63 – 450, or0.12 – 1 000 kW. Furthermore, these motors exist in three energy efficiency classes:IE2, IE3, and IE4.General performance motors form the basic motor series in the IE2 efficiency class,with less optional features than for Process performance motors, but available off-the-shelf worldwide. These motors come in frame sizes 56 – 355, corresponding to0.06 – 355 kW.Both series include cast iron4242
