I have been studying synchronous reluctance motor since a month. I am curious to know why is this motor not self starting? If used with an inverter, this motor can be made self-starting. Or by adding conductors bars on the rotor just like an induction motor, to make it line-start motor.

Synchronous reluctance motors do not have conductors or permanent magnets in their rotors. It is just iron with flux guides/barriers. There is no opposing force in this motor as present in PM motors. I am aware that if position sensor and inverter is not used, the rotor may rotate in any direction that is undesirable. Is there any other reason that this?

The main challenge includes stuff like rotor inertia and knowing the position of the rotor, without which the stator field cant be aligned in such a way to provide the required starting torque.
