... is the winding current, A is the cross area of lateral tooth, δ is the length of air gap, μ0 is the permeability of air. The coupling extents among the three phases of magnetic circuit are negligible because of 3-phase windings displaying a symmetrical distribution with 120 degree in space. Hence, to simplify the ...

... an accurate mechanical power measurement, the test bench is fitted with speed and torque transducers. Due to the torque transducer presence on the common shaft, three elastic couplings are required. As generator, a 4kW/1500rpm series induction motor is employed. Its nameplate power is the mechanical shaft power, thus, in generator ...
