Physical Properties of Coil – Calculating Physical Properties

calculating physical properties such as length, diameter, resistance, number of windings etc can be a complex task but it has been made easy with this calculator. This is an efficient electrical engineering tool.

Physical Properties

To calculate Physical Properties of Coil:

Wire Diameter

mm

Number Of Turns

turns

Bobbin Length

mm

Bobbin Diameter

mm

Current (I)

A

Turns per Winding

Number of Windings

Coil Diameter

(mm)^{2}

Cross sectional Area

(mm)^{2}

Total Length of Wire in Coil

m

Resistance/meter

ohms/m

Resistance

ohms

Voltage at Rated Current

V

Power at Rated Current

W

Formula:

T = bl / d
n = Turns/ T
cd = (2 x n x d) + bd
r = (n x d + bd) / 2
a = PI x r x r
L = (2 x PI x r x n) / 1000
rpm = .0333 *((0.812/2)*(0.812/2))/((d/2)*(d/2))
R = rpm x L
V = R x I
P = V x I

Where,
T = Turns per winding,
bl = Length of Bobbin,
d = Wire Diameter,
n = Number of windings,
cd = Outer diameter of coil,
bd = Diameter of Bobbin,
r = radius of middle of coil,
a = Cross sectional area,
L = Total Length,
rpm = Resistance/meter,
R = Resistance,
V = Voltage at Rated Current,
I = Current,
P = Power at Rated Current,

calculating physical properties such as length, diameter, resistance, number of windings etc can be a complex task but it has been made easy with this calculator. This is an efficient electrical engineering tool
