Discussion on “single-phase squirrel-cage motor with large starting torque and phase compensation” (Fynn), St. Louis, Mo., Oct. 19, 1915. (see proceedings for October, 1915)

H. Weichsel. A few words in regard to the working characteristic of this machine, might be of interest. Mr. Fynn shows in his paper, a series of test curves. A study of these curves shows that this type of machine acts very much like a synchronous motor. With a certain compensation the power factor of the machine at no-load is leading. When the load increases, the power factor approaches unity, and with still further increase of load, the power factor goes slightly below unity. An over-excited synchronous motor shows exactly the same behavior.
