Embodiment Construction

[0026] Such as figure 1 As shown, a magnetic suspension bearing dynamic torque sensor of the present invention is characterized in that it includes: a frame structure part 1, an electric drive part 2, a rotating shaft sensing part 3, a magnetic suspension bearing part 4, a signal processing part 5, and a rotational speed measurement part 6. composition.

[0027] Such as figure 2 As shown, the frame structure part 1 is the frame of the dynamic torque sensor, which bears the function of fixed connection with the external frame. In order to facilitate processing and assembly, the frame structure is divided into three parts: Body, 108 upper side shell, 102 installation base, and connect with screw 101 and screw 109. The frame structure part undertakes the function of installing the rack, which is realized by the 102 installation base. The frame structure is mostly made of stainless steel, in order to minimize the magnetic circuit interference of the electric drive part. 106 i...
