14 Appendix for Motor Size 210R
14.1 General
To improve the clarity of this documentation, this chapter describes
special IndraDyn T motor characteristics that vary from the standard size
and model for size and design:
• MST210R-xxxx-FT-N0CN-D302
• MST210R-xxxx-FT-N0CN-T302
in conjunction with rotor:
• MRT210R-3N-0130
The rotor in design MRT210R-3N-0130 has been designed to be part of
the spindle. Its mechanical characteristics thus differ significantly from the
standard design of rotors for IndraDyn T motors.
Note: Note that, due to the construction of the rotor as a part of the
spindle and the resulting increased shape and position
tolerances, this rotor design is not suitable for highly precise
applications.
The construction of the rotor as a part of the spindle is shown
schematically below; the special feature for cooling the stators is also
described. Detailed information and notes can be provided by the
machine manufacturer only after the entire system has been designed.
