CANNED SYNCHRONOUS MOTOR

PROBLEM TO BE SOLVED: To provide a canned synchronous motor capable of establishing gastightness without efficiency degradation and speed restriction by inserting a can with high design flexibility and no loss with a synchronous motor into a sealed motor, where a partition wall is formed between a stator space and a rotor space and where the rotor space and the stator space are separated in gastight from each other by the partition wall. SOLUTION: This canned synchronous motor consists of a stator 11 having a core teeth 15 and wound with a stator wire loop, a rotor 12 embedded with a permanent magnet 16, and a can 16 inserted in a clearance 13 between the stator 11 and the rotor 12.
