7.4.6 Minimum distance between the motors
a) Motor cables pointing away from each other
b) Motor cables pointing in the same direction
c) Motor cables pointing towards each other
x
min
= minimum distance between the motors
n = auxiliary variable
a = distance between phase line and housing wall of motor 1 (see previous page)
b = distance between phase line and housing wall of motor 2 (see previous page)
r
min
= Minimum bending radius of the motor cable (see section entitled Technical data [ } 50])
Calculation for example a): Calculation for example c):
(AL2006 and AL2012 motor) (AL2006 and AL2012 motor)
n‘ = (23 + 22) / 16 = 2.81 n‘ = (43 + 46 + 96 + 96) /16 = 17.56
n = 3 (rounded up) n = 18 (rounded up)
x
min
= 3 * 16 – (23 + 22) = 3 x
min
= [18 * 16 – (43 + 46 + 96 + 96)] + 96 + 96 = 199
