6-2 Type Codes Rexroth IndraDyn T
DOK-MOTOR*-MBT********-PR03-EN-P
Type Codes for Stator MST
1. Product
MST is the designation of an IndraDyn T stator unit.
2. Motor Frame Size
The motor frame size is derived from stator dimensions and represents
different power ranges.
3. Motor Frame Length
Within a series, the graduation of increasing motor frame length is
indicated by ID letters in alphabetic order. The higher the motor frame
length, the higher the torque.
Frame lengths are, for example, A, B, C and D.
4. Winding Code
Winding codes "0010", "0027", etc. act to differentiate the winding variants
and indicate the rated speed.
Example: The rated speed for the winding “0027” is n
N
= 270 rpm
.
The
intermediate circuit voltage of 540 V
DC
. is a fixed reference value.
A drive combination is selected based on the corresponding selection
data and operating characteristics.
5. Type of Cooling
The IndraDyn T motors are always fitted with a stator-cooling jacket for
operation with liquid cooling.
The MST130 also has the option “Natural convection”, while the
MST530 has the option “Surface ventilation”.
Operation without liquid cooling is permitted only under certain conditions.
In general, reduced power data apply here. For notes, see chapter 9.5
“Motor Cooling”.
6. Encapsulation
The thermal encapsulation consists of an aluminum cooling jacket,
ensuring the thermal isolation of the motor and the machine.
The MST130 also has the option standard encapsulation (only in
combination with the “natural convection” cooling type). In the standard
encapsulation, the stator package is installed in the machine housing
without a cooling jacket.
7. Motor Encoder
IndraDyn T motors are available without a motor encoder. For information
about the selection of motor encoder, see chapter 9 “Application notes”.
