How do I choose a motor wire size?

The cable size is equal to the 1.5 times of the full load current of the motor/load. Hence the cable rating formula can be written as,

Cable size = 1.5 x Full Load Current

.

How do you calculate motor winding wire size?

Refer to the manufacturer's specification regarding the winding or measure it with a micrometer from the center of the wire coil to the outer section of the coil. Call this value “r.”

A = 3.1415 * (1.5)(1.5)

= 7.068 square meters. Find the number of wire turns and the length of the wire.

How do I size a motor overload?

The overloads are determined using 125% of the FLA, 7A x 1.25 = 8.75A. The maximum allowable size for the overloads is

9.8A

. The overloads can be sized at 140% of the FLA if the overloads trip at rated load or will not allow the motor to start, 7A x 1.4 = 9.8A.

How many windings does a motor have?

The number of slots depends on how many phases of power are provided to the coil windings. A basic single-phase motor usually has

four slots

that contain two pairs of coil windings, each offset by 90 degrees; a basic three-phase motor has six slots with three pairs of coil windings, each pair offset by 120 degrees.

How do you calculate winding area?

The Total Winding Area thus needs to be calculated first, it's as follows:

Total Winding Area = (Primary Winding Area + Total Secondary Winding Area) × Space for External Insulation

. The third parameter i.e. the space for the insulation/former etc.

How do you calculate the length of a coil?

To obtain the coil length we have to

divide the result by the section of the coil determined by coil width and thickness

. The coefficient 1000 is used to compensate the dimensions in [mm] with the length in [m]. For example, a coil with OD = 1600mm, ID = 508mm and T = 0,6mm results in a length of 3010 meters.
