Problems solved by technology

When the common motor propeller is working, the fluid hinders the advancement of the propeller, forcing the bearings between the stator and rotor to bear a huge force, causing serious wear to the bearings, and due to the friction between the stator and rotor bearings, resulting in The noise of the motor propeller is difficult to suppress. Although the control optimization of the motor can reduce the noise to a certain extent, it has not been fundamentally improved in structure, so the effect is not ideal

Abstract

The invention discloses a permanent magnet conical propulsion motor and an aircraft. The permanent magnet conical propulsion motor comprises a stator (2) and a rotor (3) which are installed in a machine shell (1), the stator (2) and the rotor (3) are matched with each other through a bearing (6), the rotor (3) is connected with one end of a transmission shaft (5), and the other end of the transmission shaft (5) penetrates out of the machine shell (1) and is connected with a propeller. The inner wall of the stator (2) and the outer wall of the rotor (3) are parallel to each other and form a certain included angle with the axis of the motor, and an air gap is further distributed between the inner wall of the stator (2) and the outer wall of the rotor (3). The permanent magnet conical propulsion motor provided by the invention has the advantages of simple and compact structure, low bearing friction loss, high propulsion efficiency, long endurance mileage and the like, is stable in operation performance and long in service life, is suitable for being used in different pressure environments, and has wide application prospects in various aircrafts.

Description

technical field [0001] The invention relates to a permanent magnet propulsion motor, in particular to a permanent magnet conical propulsion motor and an aircraft, and belongs to the technical field of propulsion motors. Background technique [0002] Shipping has been booming in recent years, and electric energy has been widely promoted as a more efficient and environmentally friendly new energy source. The use of electric energy as a power source for advancement is also an inevitable trend in the current development of shipping. When the common motor propeller is working, the fluid hinders the propeller's propulsion, forcing the bearing between the stator and the rotor to bear a great force, and the wear of the bearing is very serious, and due to the friction between the stator and rotor bearings, the It is difficult to suppress the noise of the motor propeller. Although the control optimization of the motor can reduce the noise to a certain extent, it has not been fundament...
