NettetDouble-layer winding. Pole pitch (τ \tau τ) = 6 slots, coil span (y y y) = 5 slots. y < τ y<\tau y < τ → \rightarrow → Short-pitch coil. As shown below, (a) is a schematic diagram of the full and short pitch coil, (b) is an expanded view, and (c) is an EMF vector diagram. B. Pitch factor. For the full-pitch coil, the single-turn coil ... NettetWhat I think is happening... The motor produces forces from its poles, not its slots. Now if you trace the U winding, you find it starts (0 degrees) in the first slot - i.e. after the first pole ... and returns (180 degrees) in the sixth slot i.e. just before the 7th pole. But keep tracing it ... it starts again in the 12th slot and returns (180 degrees) in the 7th slot.

Nettet24. feb. 2012 · We express it as the ratio of the phasor sum of the emfs induced in all the coils distributed in some slots under one pole to the arithmetic sum of the emfs induced. Distribution factor is, As pitch factor, distribution factor is also always less than unity. Let the number of slots per pole is n. The number of slots per pole per phase is m. NettetPitch Factor - Pitch Factor, the ratio of the voltage induced in a short-pitch winding to the voltage that would be induced if the winding were full pitch. Short Pitched Angle - (Measured in Radian) - Short Pitched Anglel, the coil span will be (180 - θ)° electrical (θ = angle by which coils are short-pitched and always less than pole pitch).

Nettet23. feb. 2024 · Pitch Factor(K p): It is the ratio of EMF induced in the short pitch coil to the full pitch coil.. It is given by, \({k_p} = \cos \left( {\frac{α }{2}{n^{}}} \right)\) Where n th is the order of harmonics..
