Claims

[Scope of Claim for Utility Model Registration] In an electric switch machine used for converting railway rail turnouts, in which a deceleration drive system is driven by the output shaft of an electric motor, a plurality of permanent magnets are The end of the output shaft of the electric motor is connected to the deceleration drive system through a magnetic coupling for power transmission in which a permanent magnet ring plate and a hysteresis magnetized disk arranged on the outer periphery are opposed to each other so as to have different polarities. An electric point machine characterized in that a magnetic coupling ring for position holding is provided at the opposite end of the electric point machine.
