The utility model discloses a rotational speed magnetic sensor of synchronous output of dual -redundancy, double -deck coiling inside and outside the two sets of coils who has solved present rotational speed magnetic sensor dual -redundancy structure is on same skeleton, this kind of structure is because every ring of girth difference of ectonexine can not guarantee that two sets of coils's resistance and the number of turns are in full accord, the magnetic flux that passes through respectively in same magnetic field is different, responds to then difference of the electromotive force that respectively, the dual -redundancy output signal non -synchronous problem. The utility model discloses a there are two sets of independent coils sensor inside, and the magnet steel produces magnetic field, and magnetic component is led with central subassembly component to the end terminal, and two sets of coils guarantees with two independent coilings of skeleton that two sets of coils's the numberof turns is the same with
