Technical characteristics
Type of motor
Synchronous motor with permanent-magnet excited rotor (4, 6 or 8-pole)
Type of construction
Individual components (IM 5110 acc. to IEC 60034-7)
Stator, rotor
Degree of protection
IP00 (acc. to DIN IEC 60034, Part 5): Stator, rotor
Cooling
Water cooling with T
H2O
= 25° C acc. to EN 60034-1
Standard protection - temperature
monitoring
Two KTY 84 or Pt1000 PTC thermistors in the stator winding (1x reserve)
Full protection (optional)
In addition to the standard protection 1 x PTC thermistor triplet (3 sensors in series)
Can be evaluated, e.g. using a thermal motor protection unit:
Order No.: 3RN1013-1GW10
Universal protection (optional)
Full prot NTC PT3-51-F + NTC K227
Winding insulation
Temperature class 155 (F) acc. to EN 60034 permits an average winding tempera-
ture rise of 105 K. The power data is valid for a cooling water temperature of +5° -
25° C.
Balance quality of the rotor (acc. to
ISO 1940-1)
•
Rotor with sleeve:
Depending on the particular version, pre-balanced, balance quality G 2.5
reference speed 3600 rpm or non-balanced for complete balancing after mounting
and installation
•
Rotor without sleeve:
Not pre-balanced
Motor voltage
