LINEAR MOTORS AND IT’S USE IN MAGLEV TRAIN
INTRODUCTION
A LINEAR MOTOR OR LINEAR INDUCTION MOTOR IS AN AC ELECTRIC MOTOR THAT HAS ITS STATOR UNROLLED SO THAT INSTEAD OF PRODUCING A TORQUE(ROTATION) IT PRODUCES A LINEAR FORCE ALONG ITS LENGTH.
HOW LINEAR MOTORS WORK
SPLIT A ROTORY MOTOR RADIALLY ALONG ITS AXIS OF ROTATION
FLATTEN IT OUT:
RESULT: A FLAT LINEAR MOTOR THAT PRODUCES A DIRECT LINEAR FORCE INSTEAD OF TORQUE.

Conclusion
In this work we presented a rotary engine design which is capable of implementing the High Efficiency Hybrid Cycle. It is expected that this engine will demonstrate superior volumetric efficiency, as well as fuel efficiency across a broad range of loads. The result is an engine which may offer up to 57% peak efficiency & above 50% sustain efficiency across typical driving loads. The engine is currently being prototyped, with a functioning compressor already wor ....etc
