Description

technical field [0001] The invention relates to a cylindrical induction synchronizer, which is applied to an automatic measurement system and an automatic control system of a rotating shaft mechanism, and belongs to the field of automation technology as a high-precision angular position detection element. Background technique [0002] The induction synchronizer is a high-precision micro-control motor. The existing induction synchronizers are divided into two structural forms: linear type and disc type. Among them, the linear induction synchronizer is used to measure the linear displacement, and the disc type induction synchronizer is used to measure the angular displacement. [0003] The structure of the disc induction synchronizer is shown in Figure 1. The rotor disc base plate 1 is made of an annular metal plate with a thickness of about 10mm. Four or eight rotor installation fixing holes 2 and rotor shaft holes 3 are arranged on the rotor disc base plate. A rotor winding...

AI Technical Summary

Problems solved by technology

In many applications, the radial size of the shafting is limited

[0012] Third, the rotor is installed on a plane perpendicular to the shaft system, and an adapter flange is required, which limits the structure of the measurement shaft system and is inconvenient to install and use

Especially when the installation shaft diameter is small, it is very difficult to adjust the perpendicularity between the rotor winding plane and the shaft system through the flange

[0013] Fourth, the larger the radial dimension of the rotor ring, the greater the moment of inertia of the load on the shafting, which will greatly reduce the stiffness of the shafting structure, thereby making the dynamic performance of the shafting worse

[0014] Fifth, the single pair of polar plane spiral windings of the absolute zero disc induction synchronizer has very few turns, small magnetic flux, poor signal-to-noise ratio, and low accuracy of rough readings, so it has high requirements for application circuits and operating conditions
