Based on long stator slotted effect of linear synchronous motor in high-speed maglev train,the principle of slot detection,hardware structure of the phase detector and signals subdivision with DSP were presented,the scheme of phase detection was proposed,and a new phase detector was developed based on inductive sensors and Digital Signal Processor(DSP).

A new method is forwarded to detect the rotor position for linear synchronous motor in high speed maglev train based on inductive sensor and DSP.

Inductive sensors are widely used in engineering due to their simple structures, high output capacities, good linearity, good disturbance resistance, good stability and low prices.
