5.5.2 Synchronous motor I²t monitoring
A synchronous motor by design has lower loss than an asynchronous motor,
because permanent magnets replace the magnetizing current. It is normally not
internally cooled, but discharges its heat loss by internal convection. For that reason
a synchronous motor has a different characteristic to an asynchronous motor. It is
necessary to adapt the I
2
t characteristic because the factory setting mostly does not
exactly map the present motor.
