Motor winding calculation

Calculate the number of turns: The number of turns is a basic parameter in winding, usually expressed as N. The calculation formula is:

N = (U × 10^3) / (4.44 × B × f × A × K)

Among them, U is the rated voltage of the motor, B is the magnetic density, f is the rated frequency of the motor, A is the cross-sectional area of the core notch, and K is the filling factor of the winding.

Calculate the wire diameter: The wire diameter refers to the diameter of the wire used for winding, usually expressed as d. The calculation formula is:

d = √[(4 × A × N) / (π × K × ρ × I)]

Among them, A is the cross-sectional area of the core slot, N is the number of winding turns, K is the filling factor of the winding, ρ is the resistivity of the wire material, and I is the rated current of the motor.

Calculate the winding length: The winding length refers to the total length of the wire used for winding, usually expressed as L. The calculation formula is:

L = N×l

Where, l is the length of a single turn, which can be calculated based on the wire diameter and fill factor.
