Elevator system governors include a housing, a first pulley, a second pulley, and a cable wound about the two pulleys. A target element is arranged on at least one of the pulleys and a motion sensor assembly is arranged to detect the target element and determine if an overspeed condition is present. An electromagnet is operably coupled to the motion sensor assembly that is configured to transition the electromagnet from a first electromagnetic state to a second electromagnetic state in response to a detected overspeed condition. A trigger arm is releasably connected to the electromagnet and configured to actuate a safety brake assembly with a biasing element arranged to bias the trigger arm into an actuated state with a magnetic force of the electromagnet being greater than a biasing force of the biasing element when the electromagnet is in the first electromagnetic state.
