Sprague Electric Company — The shunt-wound, constant-speed motors placed upon the market by this firm consist of two separate lines. Their round type motors are bipolar and built in frames of 12 sizes, ranging from 1/20 to 7½ H. P. The features of these machines are an almost spherical field casting or yoke and only a single field coil to energize both poles. Fig. 98 is a section of such a machine and clearly shows the principal parts. The Sprague Company also manufactures several sizes and forms of direct-current fan motors. |
