STEPPING MOTOR
The following contents and illustration shows the explanation of stepping motor’s basic principle by using a
simple structure.
Tachometer is driven by stepping motor. Its pointer moves to the full-scale immediately after the ignition
switch is turned on to enable self-calibration.
The stepping motor consists of the stator, coils, rotor, angle position sensor, exciter circuit and distribution
circuit. The stator has 6 poles and the rotor has 4 poles. 6 coils are installed in each poles of stator and
connected in series.
The rotor can be turned freely to any position by changing electric current sent through the coils. The rotor
angle position is constantly monitored by the angle position sensor, which then feeds back signal to the
distribution circuit so as to control the exciter circuit current.
