Abstract
Disclosed is a design approach for intrinsically safe electromagnetic devices such as electrically actuated valves, motors, generators, or transformers intended for and capable of safe operation in explosive atmospheres or environments. The design employs a plurality of electrically insulated, intrinsically safe circuits cooperating to induce, or in the case of a generator, create a relatively large magnetic flux in the ferromagnetic core, or iron, of these devices. A method to construct such intrinsically safe devices is disclosed. These devices can be practically used in machines, mechanisms, valves, and manned or unmanned vehicles intended for safe operation in hazardous environments, for example underground coal mines or ATEX or EX classified facilities.
