The Electromagnetic Rail Motor (ERM) can power anything from aircraft and cars, to artificial human limbs. The ERM is based on the modern rail gun. By taking the two rails and forming a ring, a continuous rotational force is created that is easily managed and controlled. The speed of rotation can be directly controlled by adjusting the voltage, similar to a gas pedal. Once the ERM powers up, the motor rotation will accelerate to its terminal speed. The blades act as both rotational shafts and as propeller blades to help cool the motor during extremely high speeds. The rail housing holds the assembly together and keeps the rails in place to counter the immense separation force.
