Electronic safety actuator electromagnetic guidance

An elevator car comprising:

• a car frame which translates along a guide rail during ascents or descents;
• a safety disposed along the car frame to selectively engage with the guide rail to selectively permit vertical elevator car movement;
• an electronic safety actuator (ESA) configured to actuate the safety and comprising:
• an ESA body secured to the car frame with horizontal maneuverability and defining a groove through which the guide rail translates during the vertical elevator car movement;
• a magnetic guide operably disposed within the groove to exert magnetic force on the guide rail;
• and
• a sensor disposed within the groove to sense horizontal distance between the guide rail and corresponding portions of the ESA body;
• and
• a control system configured to control the magnetic guide to exert a magnetic force in accordance with reading of the sensor to maneuver the ESA body horizontally,
• wherein the magnetic guide comprises:
• an electro-magnet disposed in an upper portion of the groove at one of a first and second side of the guide rail;
• a permanent magnet disposed in the upper portion of the groove at the other one of the first and the second side of the guide rail to magnetically oppose the electro-magnet in the upper portion of the groove;
• an electro-magnet disposed in a lower portion of the groove at one of a first and second side of the guide rail;
• and
• a permanent magnet disposed in the lower portion of the groove at the other one of the first and the second side of the guide rail to magnetically oppose the electro-magnet in the lower portion of the groove.
