The capacity of the pull out machines used for making the coils limits the pole pitch to less than 0.8 m.

The statement indicates that the type of pull out machines used in the production of coils imposes a technical limitation on the pole pitch, restricting it to be less than 0.8 meters. This limitation is due to the operational capabilities or physical constraints of the machinery used in the coil-making process. The pole pitch is a critical parameter in the design of electrical machines, referring to the peripheral distance between two consecutive poles of the same type (north to north or south to south) on a machine. A limitation on the pole pitch can affect the design and efficiency of electrical machines, including motors and generators, as it influences the magnetic flux distribution, electromagnetic force, and ultimately, the performance of the machine.
