The design of a novel multi-sectional linear synchronous machine and its driver are proposed in this paper. The driving method of the proposed linear motor is quite different with the driving method of the conventional linear motor.
The multi-sectional linear synchronous machine and its driver mean that the motor is composed of several individual sub-sectional units. The sub-section unit is formed by individual winding, E-core and Hall-IC. The multi-sectional design implies that the proposed linear synchronous machine can be controlled by the aspect of module. It can easier achieve the implementation and control of infinite expansion railway than the conventional linear synchronous machine.
To reduce the power consumption on the infinite expansion railway (E-core and its winding), the digital signal processor (DSP2407) with an encoder is used to dispatch the ON-OFF signal for the corresponding individual Hall-IC and winding. All of the windings are indirectly governed by the encoder. By the property of the encoder, there is only one winding is driven at a moment, that is, other windings are under rest. Therefore, the multi-sectional design is helpful for the energy management of this proposed linear motor.
