Calculation to determine the
Number of Turns
of Polyglass Tape to be applied, to carry out a proper banding
Type values in below boxes for Automatic
Calculation of Formula
Weight of windings in
kg
exposed to the centrifugal force; normally is only end winding of the rotor/armature
P
kg
(Should the slots be closed by wedges, winding weight
to be taken intio account is that of the heads only)
Maximum distance, in
mm
between
windings and axis of rotation
R
mm
Number of revolutions per minute
(rpm)
, at the
maximum speed of rotation reached by motor
N
rpm
Safety factor normally used (
eg. Ks = 5
)
Ks
-
Tensile breaking stress of the tape, in
kg/cm
(185 kg/cm at operating temperature)
C
kg/cm
Width of the tape, in
cm
, used for banding
L
cm
Determine the Tangential Force
(F)
which the banding will have to withstand,
from the following formula:
(F)
=
P x R x N
2
5.6 x 10
6
=
=
=
kg
The number of Polyglass tape turns
(n)
to be applied is obtained
from the following formula :
(n)
=
F x Ks
C x L
=
=
=
Turns
The minimum breaking load of
(n)
turn banding can be calculated
from the following formula:
Minimum Breaking Load
=
(n)
x (
C
x 2) x 2
=
=
kg
