Clutch for switch machine and electric switch machine
The embodiment of the invention discloses a clutch for a switch machine and the electric switch machine. The clutch for the switch machine comprises a rotor provided with a hysteresis ring; a stator to which a permanent magnet is mounted; and a bearing connecting the rotor and the stator; when the current load of the switch machine is smaller than a set load, the rotor and the stator can be driven by a power source of the switch machine to synchronously run, and torque is transmitted through magnetic torque between the hysteresis loop and the permanent magnet. When the current load of the switch machine is larger than the set load, the rotor and the stator can be driven by a power source of the switch machine to rotate relatively, the hysteresis ring is magnetized repeatedly by the permanent magnet, and stable hysteresis torque is generated. According to the technical scheme, a non-contact slipping mode is adopted, so that no abrasion exists between the stator and the rotor, and the fatigue resistance is good.
