AUTO RECOVERING PROTECTION OF ELECTROMECHANICAL COMPONENTS IN A HIGH MAGNETIC FIELD

An apparatus (100) protects a device (80) which has a ferrous electromechanical component which saturates in a high magnetic field (40) and draws a dangerously high electric current. A current sensor (110) senses current in excess of safe operating conditions of the protected device (80) in or near...

Summary:An apparatus (100) protects a device (80) which has a ferrous electromechanical component which saturates in a high magnetic field (40) and draws a dangerously high electric current. A current sensor (110) senses current in excess of safe operating conditions of the protected device (80) in or near the magnetic field (40). A current switch (120) is controlled by the current sensor (110) and interposed between a power supply (90) and the device (80) to interrupt the current flow to the protected device (80) when the current sensor (110)senses current flow above a threshold due to the saturation.
