EXAMPLES

[0154] This invention is related to the field of DC electric motors and can be used in the construction of electric motorcycles and all-electric vehicles with high power and low energy consumption with point-to-point control capability. Since today's electric motorcycles usually use a type of electric motor called HUB MOTOR, these motors are installed in the center of the rear wheel of the motorcycle, and in fact, the motor shell is the same wheel and therefore the motor power is limited to the central diameter of the wheel.

[0155] Power transmission in this type of motorcycle is done by timing belts. In this type of power transmission, according to the simple law of wheels and axles, it is possible to design more than five types of electric motorcycles with different powers at different speeds with a three-phase electric motor with constant power. Also, the use of this type of electric motor in the construction of electric motorcycles provides high power, the appropriate speed, and minimum energy consumption for the user and promotes a culture of using clean energy. It is worth mentioning that this three-phase electric motor made for electric motorcycle has a power of 4200 watts, which can be increased.
