Figure6-5 Typical speed/power diagram for 1PH8 three-phase synchronous motors
Note
Like those for induction motors, the data sheets for the supply voltage "ALM400V" include
additional ancillary rated points for the con󹪝guring of main spindle applications for machine
tools. These allow an extended speed range to be con󹪝gured.
The theoretical curve of the maximum permissible overload capacity is shown as a limit in
the characteristic diagrams and corresponds to value P
max
.
Note
Voltage limitation
A SINAMICS Voltage Protection Module (VPM) is required for operation at speeds of n
max,Inv
and
above. Voltage Protection Modules are available for rated currents up to 200A.
For further information, please refer to the SINAMICS S120 con󹪝guration manuals.
6.2.5 Selecting synchronous-reluctance motors
Characteristics for synchronous-reluctance motors
For synchronous-reluctance motors, the S1 characteristic (uninterrupted duty) has a response
similar to that for synchronous motors. The S1 characteristic represents the thermally maximum
possible continuous torque that can be produced.
As a result of the very low rotor losses, in the medium speed range, synchronous-reluctance
motors have a higher thermal utilization and when compared to induction motors, have a
better e󹪟ciency class. When con󹪝guring, one of two versions can be selected:
• E󹪟ciency (IE3 to IE5)
• Performance (IE2 to IE4)
