[0008] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0009] A structure and operation mode of an electric motor, the main body of which includes a driving motor and a labor-saving planetary gear train; The rotor of the driving motor is connected to a labor-saving planetary gear train, and the driving motor outputs power through the labor-saving planetary gear train; The labor-saving planetary gear train body includes: the labor-saving planetary gear train body includes: a power input sun gear, a planetary gear carrier, a power input planetary gear, a power output planetary gear, a ring gear, a power output sun gear, and a power output sun gear mounting cover; The power input sun gear is fixed on the rotor of the drive motor and is directly connected to the rotor of the drive motor; The planetary gear carrier is installed with power input planetary gears and power output gears, and is cylindrical, with a plurality of power input planetary gear mounting shafts arranged on one bottom surface, and a plurality of power output planetary gear mounting shafts arranged on the other bottom surface; The power input planetary gear is installed on the power input planetary gear installation shaft and is a double-layer gear, the large gear layer bites the power input sun gear, and the small gear layer bites the ring gear; The power output planetary gear is a single-layer gear, which is mounted on the power output planetary gear mounting shaft and not only engages with the power output sun gear, but also engages with the ring gear; The gear ring is provided with an inner gear ring and a planetary gear receiving hole, and the diameter of the inner gear ring is smaller than the diameter of the planetary gear receiving hole. The inner gear ring not only bites the small tooth layer of the power input planetary gear, but also bites the teeth of the power output planetary gear; The power output sun gear body includes a power input gear, a large shaft, a mounting and power output shaft; The power output sun gear is mounted on the power output sun gear mounting cover; The power output sun gear mounting cover is mounted and fixed on the gear ring.

[0010] The gear ring is fixed to one end of the driving motor and cannot rotate; The power input sun gear engages with the large tooth layer of the power input planetary gear, the small tooth layer of the power input planetary gear engages with the ring gear, and the power output planetary gear engages not only with the ring gear but also with the power output sun gear.

[0011] The driving motor drives the power input planetary gear of the labor-saving planetary gear system through the power input sun gear on the rotor. The power input planetary gear drives the planetary gear frame to rotate while rotating. The power output planetary gear on the planetary gear frame drives the power output sun gear to rotate, and the power output sun gear transmits power outward.

[0012] In order to more intuitively and conveniently calculate the speed, torque of the drive motor and the speed and torque of the power output gear, because it is a gear transmission, the power arm takes the original length minus twice the tooth depth as the power arm, and the tooth depth is unified to 0.2 cm.

[0013] Assume that the power generated by the drive motor is transmitted to the power input sun gear with a value of 10; the gear radius of the power input sun gear is 2 cm, that is, the resistance arm is 2 cm, the power arm and the resistance arm of the power output sun gear are the same, offset each other, and the fulcrum is at the center of the power input sun gear; the radius of the large tooth layer of the power input planetary gear is 12 cm, and the radius of the small tooth layer is 1.5 cm, that is, the power arm is 12+1.5-0.4=13.1 cm, the resistance arm is 1.5 cm, and the fulcrum is at the position where the power input planetary gear contacts the ring gear; the distance from the center of the power input planetary gear installation shaft on the planetary gear carrier to the center of the planetary gear carrier is 12+1.5=13 .5 cm, the distance from the center of the power output planetary gear installation shaft on the planetary gear frame to the center of the planetary gear frame is 5.75+2=7.75 cm, that is, the power arm is 13.5 cm, the resistance arm is 7.75 cm, and the fulcrum is at the center of the planetary gear frame; the radius of the large tooth layer of the power output planetary gear is 5.75 cm, that is, the power arm is 5.75-0.4=5.35 cm, and the resistance arm is 5.75×2=11.5 cm, and the fulcrum is at the contact position between the power input planetary gear and the ring gear; the gear radius of the power output sun gear is 2 cm, that is, the power arm is 2-0.2=1.8 cm, and the resistance arm is consistent with the power input sun gear and offsets each other.

[0014] To sum up, the speed ratio of the sun gear and the planetary gear carrier is (12+1.5+2+2)÷2=8.75, that is, the sun gear rotates 8.75 times and the planetary gear carrier rotates one circle; the speed ratio of the planetary gear carrier and the power output sun gear is (5.75+5.75+2+2)÷2=8.75; it can be seen that the rotor of the drive motor rotates 8.75 times and the planetary gear carrier rotates one circle, and the power output sun gear rotates 8.75 times when the planetary gear carrier rotates one circle. Therefore, when the rotor of the drive motor rotates one circle, the power output gear also rotates one circle, and the rotor speed of the drive motor is consistent with the speed of the power output gear.

[0015] The torque value of the torque generated by the drive motor and transmitted to the power output gear is: 10÷2×13.1÷1.5×13.5÷7.75×5.35÷11.5×1.8=63.6957644 It can be seen that the labor-saving planetary gear train has the following characteristics: The power input member speed may be equal to the power output member speed.

[0016] A small input power can produce a huge output power.

[0017] In summary, it can be seen that the drive motor can not only output more than 6 times the power generated by itself through the labor-saving planetary gear system, but also make the speed of the drive motor equal to the speed of the power output sun gear, not only realizing 100% conversion of electrical energy into mechanical energy, but also far exceeding it.

[0018] The present invention has the characteristics of strong practicality, high working efficiency and green environmental protection. It not only does not have the limitation of limited power stored by batteries as power sources and the safety hazards of spontaneous combustion or explosion, but also does not have the disadvantages of using fuel engines to drive power generation in traditional power generation systems as power sources, which consumes fuel and also emits a large amount of exhaust gas to pollute the environment.

[0019] The above are merely preferred embodiments for illustration, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
