Iron phase pair.By the way that the encoder is changed to electromagnetic type, using magnet in rotor rotation process, magnetic line of force position
It sets relationship constantly to change, electromagnetic sensor is used to receive the change information of the magnetic line of force and will become portion by processing circuit module
Part change in location is changed into electric signal and is fed back this information to external reception peripheral hardware by interface module.
In order to make magnet generate optimal magnetic line of force variation effect during rotation, further: the pole N of the magnet
Be divided into the same both ends diametrically in rotor end face with the pole S, i.e., the line of the pole N and the pole S be in the shaft of rotor
Heart line be it is orthogonal, guarantee deflecting same angle in this way, the magnetic line of force variation that electromagnetic sensor receives is the largest,
Improve the received sensitivity of electromagnetic sensor.
For the ease of incuding the position signal of magnetic pole, further: the magnet is 1~2mm with electromagnetic sensor spacing.
For optimization processing circuit module, further: the processing circuit module includes deflecting motor rotor position
Information is converted into the signal processing module of electric signal and the energy-storage module to electromagnetic encoder configuration backup power source；The interface electricity
Road module includes that the power interface for receiving power supply signal and the signal for external transmission electrical machine rotor deflection information connect
Mouthful.
Compared with prior art, the utility model has the beneficial effects that first is that due to using electromagnetic induction principle, as long as AD turns
Parallel operation digit is sufficiently high, and precision can improve；Second is that electromagnetic induction principle, can be installed separately, it is big to coaxial fixed requirement
It is big to reduce；Third is that it is small in size, it is at low cost.Fourth is that can require according to user, interface is provided, it if necessary can also be with several interfaces
It provides simultaneously.
