One of, cause magnetic field power to change when tooth peak passes through wheel speed sensors with tooth paddy on gear ring, the rotating speed of wheel is obtained with this.
The basic principle of magnetoelectric sensor is electromagnetic induction principle.According to the law of electromagnetic induction, when N circles coil is equal permanent
When being moved in magnetic field, if the magnetic flux across coil is φ, then induced potential E=△ φ/△ t in unicoil have following relationship, therefore
Its induced electromotive force is E=N △ φ/△ t under N number of coil.
And in stationary magnetic field, coil does linear uniform motion, and induced electromotive force formula can transform to E=NBLvsin θ
In formula, N is coil turn；B is magnetic induction intensity；L is the average length per circle coil：V is the speed of coil relative magnetic field movement
Degree；θ is the angle in coil movement direction and magnetic direction.
However, its simultaneously cutting magnetic line that rotate that work on real vehicle one of ABS or CS, therefore its formula can
To be transformed in E=NBA ω sin θ formulas, ω is the opposite angular speed of rotary motion；A is the sectional area per circle coil；θ is coil
The angle of the direction of motion and magnetic direction.
According to above-mentioned basic principle, magnetoelectric transducer can be divided into two types：Become magnetic flux type（Variable reluctance）With it is constant
Magnetic flux type.Magnetic flux type magnetoelectric transducer is simple in structure, secured, reliable operation, cheap due to becoming, and is widely used on vehicle
Wheel speed sensors as detection vehicle wheel rotational speed.
Induced electromotive force major parameter is influenced according to formula E=NBA ω sin θs：
（1）N coil turns（It is determined by product）
（2）B magnetic field intensities（1. product determines, 2. the air gaps）
（3）A is per circle coil section product（Product determines）
（4）The opposite angular speed (being determined by test rotary speed) of ω rotary motions
Therefore it is directed to test equipment, major control point is 1. the air gaps, and 2. turntables are with respect to angular speed.
