Fairbanks, Morse & Co. — This company manufactures several lines of constant-speed, shunt-wound motors, using the same frames as for their lines of belted generators. The separate motors range from 1.50 H. P. at 650 R. P. M., like Fig. 29, down to 2 H. P. at 1,800 R. P. M., like Fig. 28. The same frames are also compound wound giving a drop in speed of about 20% between no load and full load. They are wound to operate on 110-, 220-, or 500-volt circuits. Their smaller sizes are made in all the varieties, similar to other manufactures, and also furnish a line of adjustable-speed motors with speed variation of 2 to 1 or 4 to 1, as called for. Fig. 83 shows one of their smaller motors driving an exhaust fan. |
