Electric motors and rotor power units, aircraft

Abstract

The invention relates to a motor, a rotor power device and an aircraft. The motor includes a rotor, stators and a fixing shaft; the rotor and the stators are distributed with the fixing shaft adopted as an axis; the stators include a first stator and a second stator; the rotor is arranged between the first stator and the second stator; power output interfaces are arranged at the periphery of the rotor; when the rotor rotates around the circumferential direction of the fixing shaft, since driving radius is larger, generated driving torque is larger, and load capacity is increased accordingly; the power output interfaces are located in between the first stator and the second stator, so that stability in rotation can be improved; and a plurality of external components such as blades, which require driving, can be symmetrically arranged along the circumferential direction of the rotor, so that the load and stress of the rotor tend to be more uniform.

Description

technical field [0001] The invention relates to a motor, a rotor power device and an aircraft using the motor. Background technique [0002] Motor, commonly known as "motor", refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. [0003] A stepper motor is a control motor that converts electrical pulse signals into mechanical angular displacements, and is often used as an actuator in a digital control system. A stepper motor mainly includes two parts: a stator and a rotor. Such as figure 1 and figure 2 Shown is a schematic diagram of the structure of a three-phase stepper motor. Such as figure 1 As shown, when phase A is energized, the magnetic flux in the direction of AA1 passes through the rotor to form a closed loop. Generally, the rotor has a certain angle ...

Problems solved by technology

However, the force output end of this type of motor bears external force in a unilateral way, and the force on the output shaft of the motor is unbalanced and subjected to a large flexural moment, especially for some more sophisticated machines such as aircraft. , this unbalanced force tends to affect the overall performance of the machine

On the other hand, for this method of driving external equipment relying on the circumferential rotation of the rotating shaft, the force arm or torque of the force transmission method is small, so the consumed rotor is prone to overload and heat, reducing efficiency
