Background
The principle of the existing direct current motor is that an electrified conductor generates force in a magnetic field to rotate, and the rotating conductor cuts magnetic force lines to generate counter-electromotive force.
The formula: u=ir1+ir2+ce
n M = BILN xr from the formula: first, reversibility at rated voltage (can be generator, motor); secondly, the current and the rotating speed are changed due to the moment change under the rated voltage, and the rated current of the motor coil works for a long time without burning the maximum current born by the coil, so that the current is increased when the moment is increased, and the rotating speed is reduced to burn the coil; third, the back emf consumes much more energy than the coil resistance, and back emf is not useful work, which is determined by the existing motor structure to overcome by the back emf and output energy, and therefore is not energy efficient.
Namely: there is a need for a dc motor that is energy efficient without stalling the coil.
