发明名称 Magnetic coupling device for an elevator system
摘要 An exemplary magnetic coupling device (30) includes a core (40) having an exterior surface. An active portion (48) of the surface is configured to direct a magnetic flux associated with the core in a desired direction. An interruption (80) in the exterior surface near the active portion (48) is configured to establish a relatively high magnetic saturation in the core in a vicinity of the interruption (80).
