This motor type, called SynRM for short, is the motor of the future according to the current status. Arguments for this are that the synchronous reluctance motor:

Is simply constructed
Is sturdy and durable
Contains only common raw materials
Capable of high speeds
Usually has a high overload capacity
is easy to service and repair
has the best efficiencies
In almost all partial and overload loads
In almost all speed ranges
Suitable for high outside temperatures
Is good to recycle
