Provided are an electromagnetic driving device that is resistant to failure, highly practicable, safe and reliable and of a simple structure, and methods for manufacturing and controlling the electromagnetic driving device. The present invention aims to provide an electromagnetic driving device able to operate and serve the function of driving even if a power supply system of an electromagnetic clutch malfunctions or a sudden power cut occurs, avoiding the series of adverse effects brought about by the failure of the electromagnetic clutch. The electromagnetic driving device comprises a driving disc (102; 202; 302; 402; 502; 602), and also a first driving device (106; 206; 306; 406; 506; 606), a second driving device (107; 207; 307; 407; 507; 607) and a first electrical control device (103, 104; 203, 204; 303, 304a; 403, 404; 503, 504; 603, 604). When the first electrical control device (103, 104; 203, 204; 303, 304a; 403, 404; 503, 504; 603, 604) is energized, the first electrical control device (103, 104; 203, 204; 303, 304a; 403, 404; 503, 504; 603, 604) drives the first driving device (106; 206; 306; 406; 506; 606) such that the second driving device (107; 207; 307; 407; 507; 607) is disengaged from the driving disc (102; 202; 302; 402; 502; 602). When the first electrical control device (103, 104; 203, 204; 303, 304a; 403, 404; 503, 504; 603, 604) is denergized, the first electrical control device (103, 104; 203, 204; 303, 304a; 403, 404; 503, 504; 603, 604) drives the first driving device (106; 206; 306; 406; 506; 606) such that the second driving device (107; 207; 307; 407; 507; 607) is engaged with the driving disc (102; 202; 302; 402; 502; 602). |
