ELECTRIC MOTOR SYSTEM INNOVATION IS ESSENTIAL

ELECTRIC MOTOR SYSTEM INNOVATION IS ESSENTIAL:

Although today’s rare-earth permanent magnet (RE-PM) electric motor system is anecdotally considered the most efficient and compact, the electric motor system community is ethically searching for innovation that will reduce (if not eliminate) RE-PMs, which are monopolized by a global adversary seeking world dominance with harmful emissions, such as net zero carbon, material shortages, such copper and rare-earth materials, electric motor innovation, exploited labor, human rights, environmental, and geopolitical consequences:

Today’s advances in electric motor system (EMS) innovation is technically limited to “me-too” electric machine systems, which are always with the “non-optimal asymmetry” of a wasteful “passive rotor” comprising either slip-induction windings, reluctance saliencies, rare-earth permanent magnets (RE-PM), or DC field windings that reasonably consumes half of the electric motor system cost, loss, and size, while including associated friction, electronic control, and enabling components for consistently maintaining the air-gap flux density during rotation, but cannot contribute additional active power to the electromechanical energy conversion process along with the universally essential “active stator” for primary torque and working-power production. Instead, the symmetric EMS, as only provided by SYNCHRO-SYM with brushless and sensor-less real-time emulation control (BRTEC), with the symmetry of active rotor comprising another directly-excited multiphase winding set (as found on the active stator) provides another increment in working power to the electromechanical energy conversion process, which in accordance to EMS physics, provides 2-8x the performance/price with the same packaging as any other (i.e., asymmetric) EMS.

Although the EMS is the backbone of the industrial and commercial electricity infrastructure as well as the electric transportation infrastructure, the question isn’t “Will the electric vehicle (EV) dominate the transportation market in order to motivate electric motor system innovation?” Instead, the question should be “What is the best propulsion drivetrain solution for any type of vehicle, regardless of fossil, hydrogen or battery fueled,” which will more efficiently and reliably replace the “gearbox and differential mechanical drivetrain” of today’s so-called EVs, which is necessary to improve peak torque and to reduce the amount of RE-PM materials with a smaller, ultrahigh speed asymmetric RE-PM electric motor system? By ignoring the established mechanical drivetrain infrastructure or the monopoly on EMS innovation by a global adversary, most would choose the “electromagnetic drivetrain” with high peak torque, direct-drive (gearless) electric motor and generator systems, and high power and energy storage ballast for energy recovery, such as supercapacitors and batteries, as the best solution but only provided by SYNCHRO-SYM. 

As the following informal rendering shows, two SYNCHRO-SYMs can replace the typical EV high speed asymmetric electric motor system package with its complementary high frequency electronic controller, speed-reduction gears, and differential (e.g., Vitesco EMR-3 or EMR-4) without increasing the original package size, loss, or cost but delivering twice the power, twice the reliability, half the complexity, and rapid precision independent torque vectoring of the two wheels, full electromagnetic braking, full regeneration, etc.:
