Specific embodiment
A kind of triplex redundance rotation-speed measuring device based on magneto-electronic theory of the utility model, including end cap 1, armature 2, skeleton 3,
Column 4, shell 5, permanent magnet 6, bushing 7, ground line 8, electric connector 9, conducting wire 10 and enameled wire 11.3 surface insulation of skeleton is stood
Column 4 is mounted on the circular hole 12 of 3 end face of skeleton, and blend compounds stick agent and fix, and enameled wire 11 divides three groups to be wound on skeleton 3, and six
The circular hole of circular hole 12 and column 4 that terminal passes through skeleton 3 is welded in the semi-circular recesses 13 of column 4, and armature 2 is mounted on bone
Inside frame 3, the both ends of permanent magnet 6 are fixed by skeleton 3 and bushing 7, and conducting wire 10 is welded on the circular hole 14 of 4 end face of column, conducting wire
Other one of 10 passes through bushing 7 and is connected on electric connector 9, is grounded one of 8 and is connected on electric connector 9, ground line 8
Other one be stuck in the gap of shell 5 and electric connector 9, electric connector 9 and shell 5 are welded and fixed, and the inside of shell 5 is completely
Sealant pouring and sealing, end cap 1 are threadedly coupled with shell 5.
Permanent magnet 6 magnetizes armature 2, the magnetic field that external magnetic conduction rotary part cutting armature 2 is launched, the enamel-cover after coiling
Corresponding induced electromotive force is generated inside line 11, and electric connector 9 is transferred to by conducting wire 10, exports corresponding electric signal.
Enameled wire 11 divides three groups of independent coiling forms, can form three groups of coils, can acquire three groups of independent signals, increases
Add design remaining, improves reliability.In the form of three groups are independent, different radial zones is wound on skeleton 3 enameled wire 11,
First group of enameled wire is directly wound on skeleton 3, and second group of enameled wire is wound on the coil outer diameter that first group of enameled wire turns to
On profile, third group enameled wire is wound on the coil outer diameter profile that second group of enameled wire turns to.
