Rexroth IndraDyn A Type Codes
6-3
Motors ordered with a keyway are always supplied with a key .
Centering holes with a "DS" thread according to DIN 332, Sheet 2 are
located on all motor output shafts. Details are contained in the respective
motor dimension sheets.
See the sections regarding the shaft seal and the output shaft in Chapter
9, ”Application Notes”.
9. Holding Brake
MAD100-180 and MAF100-160 can be supplied with integrated holding
brakes with different holding torques. Depending on the application, an
"
electrically-clamping
" or "
electrically-releasing
" holding brake can be
selected.
Note:
The motor holding brake is not suitable for protection of
personnel or as a service brake! Heed the notes regarding
holding brakes in Chapter 9, "Application Notes" and Chapter
12.1, "Commissioning ".
10. Frame Shape
IndraDyn A motors are supplied in the frame shape
05
(flange mounting)
or frame shape
35
(flange and foot installation). The permitted conditions
of installation are explained in Chapter 9, "Application Notes".
11. Bearings
The standard bearing (option "
N
") consists of deep-groove ball bearings
in all IndraDyn A motors.
Reinforced bearings (option "
V
") can be used in order to bear greater
radial forces. With reinforced bearing, there is an additional cylindrical-
roller bearing at the drive side next to the deep-groove ball bearing.
High-speed bearings (option “
H
“) consists of a deep-groove ball bearing
and permits higher speeds at a reduced axial and radial load-bearing
capacity.
The bearing for the coupling attachment (option “
R
“) consists of a deep-
groove ball bearing. This type of bearing has a special bearing seat to
absorb rotary radial forces that may occur in motor operation with a
coupling.
Heed the notes regarding holding brakes in Chapter 4, ”Technical Data
….” and Chapter 9, "Application Notes".
12. Vibration Severity Class
IndraDyn A motors are dynamically balanced according to the
requirements of DIN ISO 2373; the standard is class "
R
". With frame
sizes MAD/MAF100-180, options
”S”
and
”S1”
can be selected.
