Abstract: The present disclosure relates to an AC/DC closed-loop current sensor, including a magnetism gathering iron core, a TMR chip, a signal processing circuit, a signal generator, and a feedback coil. The TMR chip is arranged at an air gap of the magnetism gathering iron core and connected to the signal processing circuit. The signal processing circuit is connected to the signal generator. The feedback coil is wound around the magnetism gathering iron core and connected to the signal generator. The signal processing circuit is configured to select from the induced signal of the TMR chip and make an amplification to obtain a current signal component and send the current signal component to the signal generator. The signal generator is configured to adjust a current output to the feedback coil based on the current signal component, and output a measurement result of the selected current signal component.

Abstract: A linear positioning platform and a linear positioning system based on magnetic transmission are disclosed. The linear positioning platform includes a moving magnetic linear motor module and a magnetic transmission linear positioning module. The moving magnet linear motor module includes a base, a stator coil, a first yoke, and motor poles. There is a gap between the stator coil and motor pole.
