π³ππ = [π.π (π«+π ππ)/πΊπ ] + πππππ ππππ + ππ³
π³ππ = [π.π (π«+π ππ)/πΊπ ] Γ πππππ ππππ ΓΒ ππ³
π³ππ = [π.π (π«+π ππ)/πΊπ ] Γ πππππ ππππ + π³

Quick Summary: The length of a mean turn of each coil per pole in the design of a single-phase induction motor is given by the formula $L_{mt} = [8.4 (D+d_{ss})/S_s] imes ext{slot span} + 2L$. This formula is crucial for designing the motor to achieve optimal performance.
The length of a mean turn of each coil per pole in the design of a single-phase induction motor is given by the formula Lmtβ=[8.4(D+dssβ)/Ssβ]ΓslotΒ span+2L. This formula is crucial for designing the motor to achieve optimal performance.
Lmtβ=[8.4(D+dssβ)/Ssβ]ΓslotΒ span+2L β length of a mean turn of each coil per pole
D β diameter of the stator
dssβ β diameter of the slot span
Ssβ β number of slots per pole
The working principle behind this formula involves considering the physical dimensions of the motor, including the diameter of the stator, the diameter of the slot span, and the number of slots per pole. The formula takes into account the span of the slots and the length of the coil ends to calculate the mean turn length.
