  • Exercise apparatus with a magnetic resistance
    Patent number: 9186550
    Abstract: Exercise apparatus (1) in which a person exercising exerts a force against a movable actuator (6) to which is applied an adjustable force by a load system which resists or assists the movement of the actuator and is connected to the actuator by cables (9). The load system comprises a fixed, longitudinally arranged coaxial series of coil units (15), each coil unit being independently connectible to a source of electric current. The series of coils provides an elongate passage (18), and a shuttle (19) of ferromagnetic material is mounted for relative longitudinal movement within the passage, in response to movement of the actuator. Passage of a current through a coil unit exerts a force on the shuttle when in that coil unit, and is controlled by a microprocessor (22).
