ABSTRACT: This paper presents a novel idea of utilizing the reactional torque of
the conventional electric motor as a linear output for propulsion in addition
to the conventional torque output of the rotor. The idea is demonstrated by a
theoretical proposal of linearizing the stator of one of the most used motors in Electrical Vehicles and Hybrid Vehicles. The proposed Linear Stator Motor is a simple
modification without involving any functional change of the conventional motor.
Though theoretical, the indicated possible input energy saving of more
than 75% as compared to the conventional motor is no surprise, as by
linearizing the stator, an almost equal linear propulsion output is added to
the conventional rotor output. In addition to this remarkable saving in input
energy, the proposed Linear Stator Motor that suits all types of vehicles, can maintain propulsion
without the need for a mechanical transmission system. Also, in the case of watercraft and
aircraft vehicles, no external mechanical propulsion drive system is required.
It is just an internal force that can push the vehicle forward, backward, or laterally, while the
conventional rotor output can be utilized for energy recovery by driving a DC
generator.
