Harry W. Jeannin, formerly of Century Electric Co., left that company about 1915 and worked for a time as an independent consultant. He obtained a series of patents for single-phase repulsion-start induction-run motors, and then in about 1918 took employment with American Magneto Co., who relocated from Michigan to Toledo, licensed Jeannin's patents and planned to start manufacturing motors. In late 1918, American Magneto went bankrupt; it appears that Jeannin bought back the rights to his patents at the receiver's auction, and in early 1919 started Jeannin Electric Co. to manufacture his line of motors. Jeannin repulsion-induction motors are of a type well suited to most woodworking machines because they have good starting torque. The company continued until Jeannin's death in 1929. The following year, the assets were purchased by Howell Electric Motors Co. of Michigan.
