Selecting the MOVIGEAR
®
performance drive unit
Observe the following procedure when selecting the MOVIGEAR
®
performance drive
unit:
1. Which torque class (size) is required?
Requirement:
The maximum possible startup torque of the MOVIGEAR
®
perform-
ance drive unit must be higher than the maximum application torque:
M
M
apk
max
≤
Due to the application calculations, the maximum application torque is M
max
=
145 Nm
MGF..2-..-C drive units with i > 10.37 meet these requirements.
Result:
A MOVIGEAR
®
performance of torque class MGF..2 is selected.
2. Selecting the ratio with output speed:
Requirement:
The application calculations result in an output speed of n
a
=
50 min
-1
. To achieve a high setting range and optimum efficiency, the required out-
put speed should be achieved as precisely as possible at an input speed of
n
e
= 2000 min
-1
.
Result:
The drive with a ratio of i
tot
= 37.24 and an output speed of n
a
= 53.7 at
n
e
= 2000 min
-1
is selected from the table in the chapter "Technical data" > "Selec-
