Calculate the coil pitches and indicate the slots into which the first coils should be placed for the following armature windings: (a) 36 slots, 4 poles; (b) 57 slots, four poles; (c) 76 slots, 6 poles; (d) 132 slots, 8 poles; (e) 270 slots, 10 poles. 2. The armature of a 6-pole generator carries a total of 350 A. Basic AC Motor Operation. An AC motor has two basic electrical parts: a "stator" and a "rotor" as shown in Figure 8. The stator is in the stationary electrical component. It consists of a group of individual electro-magnets arranged in such a way that they form a hollow cylinder, with one pole of each magnet facing toward the center of the group.

E XPERIMENTAL RESULTS. In order to carry out the experimental test, the winding diagram in Fig. 3 was applied to a 4-kW, 4-pole, 112-Frame, squirrel-cage induction motor. Two test-coils were. Slots may be completely open or semi closed. Semi closed slots are preferred for induction motors because with their use the gap contraction factor is small giving a small value of magnetizing current. The use of semi enclosed slots results in low tooth pulsation loss and a much quieter operation as compared with that with openslots. 4. Stator. The AF16-40-00-13 is a 4-pole DIN-rail mount AC/DC operated Contactor with screw terminals for controlling power circuits. It is mainly used for controlling non-inductive or slightly inductive loads. This contactor includes an electronic coil interface providing reduced pull-in and holding consumption, particularly for AC control circuits. It offers extended operating limits and is suitable.
