High-Frequency Portable Tools and Equipment
Transactions of the American Institute of Electrical Engineers, 1929This paper presents practical information regarding the application of high-frequency (180-cycle) induction motors with low-resistance rotors to portable electric tools. In order to compete with existing tools it became necessary to increase the rotor speed above that of 60 cycles, and 180 cycles per second was adopted as commercially practical ...
