Description

Technical Field

[0001] The utility model relates to a ducted motor, in particular to a tail thrust ducted motor, belonging to the technical field of motors. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetic-electrical power rotation torque. Electric motors are divided into DC motors and AC motors according to the power source used. Most of the motors in the power system are AC motors. The working principle of the motor is that the magnetic field acts on the force of the current to make the motor rotate.

[0003] The utility model with patent number CN219204254U discloses a brushless ducted motor, including a housing, a rotating shaft is arranged inside the housing, and a fan blade is installed at the first end of the rotating shaft. In the utility model, the outer side of the fixed base is zero-matched with the housing, and the fixed base and the inner housing can be installed together by pressing the fixed base into the inner housing during installation, and it is not necessary to use fasteners such as bolts to connect, which is convenient for installation; the first bearing and the second bearing are distributed at the end of the rotating shaft or near the end, and the exposed parts at both ends of the rotating shaft are shorter, thereby reducing the amplitude of the swing, so as to reduce the vibration of the motor, and further reduce the noise of the motor.

[0004] In order to save costs and reduce the weight of the drone industry, a large amount of plastic materials are used. Ducted motors generate more heat when running at high speeds. Although the device in the above patent improves the stability of the motor operation, the heat generated by the motor can easily be transferred to the drone through the outer casing, causing fusion of the joints. For this reason, we provide a tail thrust ducted motor to solve the above problem. Utility Model Content
