PURPOSE: To measure the no-load property of a rotating electric machine with accuracy and besides simply. CONSTITUTION: Windings 3 are applied in toroidal form for every pole to the slots S0, S1, S2, ... of a stator iron core 1. In this case, the number of windings is set so that the distribution of magnetic flux of the teeth 1a of the stator iron core 1 may be in sine wave. A rotor iron core 2 is arranged through a uniform gap inside the stator iron core 1. When winding is supplied with electricity, the magnetic flux flowing in the teeth la of the stator iron core 1 turns out to be distributed in sine wave similar to the time of operation of a rotating electric machine. |
