Utilizing the Reactional Torque of the Conventional Electric Motor as a Linear Output for Propulsion: A Novel Idea

The reactional torque of a normal electric motor, in addition to the rotor's usual torque output, is presented in this study as a unique approach for propulsion. Electric motors play a crucial role in modern industrial and domestic applications. With the trend of more and more electric drives, such as electric vehicles (EVs), the requirements for electric motors become higher and higher, e.g., high power density with good thermal dissipation and high reliability in harsh environments. A theoretical proposal to linearize the stator of one of the most popular motors in electrical and hybrid vehicles serves as an example of the concept. The suggested linear stator motor is a straightforward upgrade that doesn't include any functional adjustments to the standard 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 and in the case of space crafts no fuel shooting out is required. It is just an internal force that can push the vehicle forward, backward, or laterally, while the conventional rotor out- put can be utilized for energy recovery by driving a DC generator.
