Synchronous motor high starting current
These are permanent magnet synchronous motors, so there is no high (600%) starting current as there is in an induction motor. High starting current in an induction motor are the result of the extremely poor power factor because the stator and rotor frequencies are so far apart initially. In a PM motor like this, there is no rotor current, the magnetic field is always there by virtue of the magnets.

But that does not mean there is NO inrush current. Anything that has a coil will have inrush current because for the brief moment (1-2 cycles) that power is first applied and no magnetic field interactions are yet taking place, the two ends of the coil represent a short circuit. In addition, anything with a capacitor will have inrush current to charge the capacitor, and your motor SHOULD have a capacitor considering that it is a 3 phase motor that can run on single phase input, so long as the capacitor creates the initial phase shift to start it turning. So between the coil and capacitor inrush currents, you DO still have the possibility of blowing fuses, especially those that are not "time delay" type.
