Synchronous motor (SM): Compensate temperature and current influences
The properties of the permanent magnets of permanently excited synchronous motors
depend on the temperature and the amperage. The relationship between motor current and
resulting torque changes correspondingly.
The influences of the temperature and the amperage on the magnetisation can be taken into
account by the motor control and hence be compensated for.
•
To compensate for the temperature dependence of the magnets, the temperature coeffi-
cient (kT) of the permanent magnet must be entered in object
(linear charac-
teristic).
•
To compensate for the current dependence of the magnets, multiple grid points of a char-
acteristic must be entered in the following object (non-linear characteristic):
