Calculation methods used in maintenance of seven kinds of high voltage motors
- Feb 02, 2018 -

One of the most common calculation methods for high voltage motor maintenance: The number of slots divided by the maximum span equals the series (the series is even 2, 4, 6, 8, 10 ...). When the result is equal to the decimal number, take a close even number, such as 3.8 even level 4.

High-voltage motor maintenance commonly used calculation method of two: 5760 divided by the series equals speed.

High-voltage motor maintenance of the common calculation method of three: Circular line cross-section area equal to the radius of the square multiplied by 3.14.

High-voltage motor maintenance of the common calculation method of four: aluminum wire to the copper line is equal to the cross-sectional area multiplied by 0.85.

High-voltage motor maintenance of the common calculation method of five: flat-line cross-sectional area is equal to the thickness times the width multiplied by 0.95.

High-voltage motor maintenance of the common calculation method of six: A change of two is equal to two of the cross-sectional area of the sum (two wire diameter The closer the better).

The usual calculation method of high voltage motor maintenance Six: The line mode circumference equals trough od (trough bottom to opposite trough bottom) multiplied by 3.14 divided by the slot number multiplied by the span iron core length times 2.

High-voltage motor maintenance commonly used in the calculation of the seven: the coil span can be divided by the number of series, just about the span, such as 36 groove 4 motor Winding is 1x8, 2x9, but 48 slots 4 double layer has 1x11, 1x12, 1x13, and other stepover.
