【正文】 f several thousand horsepower and above are built with bartype rotors. Another construction feature dependent in motor size is the type of coil winding small and mediumsize ac motors, most coils are coils are made with round wire, which is wound into the stator slots and assumes a diamond shapr in the end turns; however, the wires are randomly located within a given coil, and hence the name “randomwound.” For large ac motors and particularly for highvoltagemotors, 2300V and above, formwould coils are coils are construted from rectangular wire, which is bent into shape around forms and them coil is formed to the proper size so that the plete coil can be inserted into the stator slots at the time the stator is wound coils are used for highvoltage windings because it is relatively easy to add extra insulation on the individual coils before inserting them into the stator. 。 在制作定子繞組時 , 線圈被做成適當?shù)某叽?, 以便將整個線圈置于定子槽中 。 對于大型交流電動機尤其是高壓電動機 , 如 2300V 以上的電動機 , 則采用模繞線圈 。 這些線圈采用的是圓截面導(dǎo)線 , 這些導(dǎo)線繞置在定子槽中 , 并將其端部繞置成菱形 。 另一個與電動機容
