Fig. 36—Showing Crocker Wheeler Motor Armature with Coil Terminals Unsoldered. Alternating current transformers for the production of high voltages may be broadlyclassified under two general types: (1) The constant current transformer; (2) The constant voltage terms of the ratio of transformation, they may be classified as: (1) Step-up transformer; (2) Step-down transformer. According to the design of the coils and the core or magnetic circuit, they may beclassified as: (1) Open core transformer; (2) Closed core transformer; (3) Auto transformer; (4) Air core transformer. Fig. 37 is an elementary diagram of a closed core, step-up, constant voltage primary and secondary windings P and S respectively, are supported by a rectangulariron core built up of strips of sheet iron. The primary winding, for example, may consistof one or two layers of comparatively coarse wire such as No. 10 or No. 12 B. & S. secondary winding S may have several thou
