Hypermagnetic electric motor

**Hypermagnetic electric motors** (HMEMs) are the modern standard for motors in most civilian and military vehicles in the Coalition of Congressional Republics, being introduced in the late 2100s to phase out early iterations of electric motors. Drawing power either from advanced batteries or compact energy reactors, HMEMs utilize powerful electromagnetic fields to maximize the mechanical output.

The fundamental working principle of HMEMs revolves around the interaction of the magnetic fields generated by electromagnets and sustained by superconducting materials. As electrical current flows through the superconductor coils, magnetic forces act upon the permanent magnets, inducing rotational motion in the motor shaft. The optimized magnetic flux control and ferromagnetic core materials amplify this effect, resulting in powerful, efficient propulsion.

## Function

For the production of magnetism, HMEMs incorporation of rare-earth elements such as neodymium, samarium, and dysprosium into the motor's construction. These elements are alloyed with other materials to create powerful neodymium-based magnets, ensuring intense magnetic fields within the motor's core. HMEMs utilize a highly sophisticated coil system comprising of superconducting materials to generate strong electromagnetic fields. These coils are wound with extreme precision to ensure efficient energy conversion and minimize resistive losses. The motor's core is constructed from high-permeability ferromagnetic materials, typically incorporating iron-silicon alloys and laminated cores. These materials facilitate the concentration and propagation of magnetic flux within the motor, ensuring optimal torque and power output.

To optimize motor performance, HMEMs employ novel techniques for magnetic flux control, involving precise manipulation of magnetic field strengths and orientations within the motor. This is possible thanks to magnetic field regulators composed of iron-cobalt alloys, which maintain consistent magnetic flux and prevent unwanted interference.

This entire system is encased within a shielded shell to prevent the magnetism of the motor from going beyond where it is intended.

### Power

HMEMs can draw power from two distinct sources, depending on the weight and energy demands of the vehicle. For lightweight vehicles, advanced lithium-sulfur batteries with unprecedented energy densities are employed. For heavier or more energy-intensive applications (such as in military vehicles), compact energy reactors utilizing fuel cells are available.

## Advantages and disadvantages

### Advantages

HMEMs exhibit industry-leading energy efficiency, minimizing energy waste and heat generation. The high torque output of HMEMs allows for rapid acceleration, critical in the modulation of speeds for vehicles such as hovercars.

The use of superconducting materials and advanced alloys ensures reduced wear and tear, minimizing maintenance requirements, and the ability to switch between batteries and reactors makes HMEMs versatile for various vehicle sizes and missions.

### Disadvantages

HMEMs are highly complex and require advanced materials and manufacturing techniques, making them expensive to produce and maintain. The use of rare-earth elements and superconducting materials drives up the initial cost of these motors, and repairing or replacing components can be prohibitively expensive on worlds that lack these materials or a logistics line to support it.

While HMEMs are designed for minimal maintenance compared to traditional internal combustion engines, when they do require maintenance or repair, it can be complex and time-consuming. Specialized technicians and equipment may be necessary, leading to extended downtime for vehicles in areas where this is in high demand. The incorporation of strong magnets, superconductors, and specialized materials can also add significant weight to the vehicle. While this may not be a major issue for heavy-duty vehicles, it can impact the overall efficiency and handling of lightweight vehicles, thus yielding even more expenses for the latter.

The powerful electromagnetic fields generated by unshielded HMEMs can pose safety risks to passengers.

If connected to dealer servers, an HMEM may be vulnerable to hacking or cyberattacks, potentially allowing malicious actors to gain control over vehicular function or disrupt transportation networks.
