Description

Axial flux motor fluid delivery module

The present disclosure is an axial flux motor fluid delivery module that provides for fluid delivery in a pipeline or open space.

In fluid delivery modules, the most common devices are pumps and fans. The purpose of the pump is to pressurize the fluid in the tubing so that the fluid overcomes the flow impedance within the tubing system.

Basically, the pump can be roughly classified into a turbine type (or a turbine type), a displacement type, and other special types (such as a water hammer pump, a vortex pump, etc.), and the artificial heart is similarly pumped except for an industrial pump. The general pump configuration places the motor outside of the pump body, making the pump's volume appear bulky and therefore needs to be improved.

In addition to pumping, the second common device is a fan. Fans, also known as fans, belong to the fluid machinery in the machinery industry, so fans have been widely used in industrial and consumer life, and fans can be divided into industrial fans, and household and home appliances fans.

The main use of industrial fans includes air conditioning systems, factory ventilation, gas delivery on processes or heat dissipation from electromechanical products; fans for household and home appliances include electric fans, range hoods, wall fans or bathroom exhaust fans; It is known that fans are closely related to people's daily lives, so the importance of fans cannot be ignored.

As mentioned above, due to the wide use of fans, there are many types of fans. If the fan is classified according to the basic mechanical type and principle, it can be divided into axial flow. Fans, centrifugal fans and diagonal flow fans, of which the special one is a diagonal flow fan. The main function of this type of fan is to increase the flow rate in the piping system and provide a slightly higher static pressure.

Today's diagonal flow fans are used for exhaust or exhaust in small piping systems. Diagonal flow fans can be used as relay fans or main fans for piping systems, while another major use for diagonal flow fans is For the household range hood, the diagonal flow fan is configured by separating a motor from a fan system, and does not hide the motor in the fan system. This also causes the diagonal flow fan to be a bit criticized, that is, the volume is too large. The inconvenience of the diagonal flow fan is caused, so the diagonal flow fan still has room for improvement.

In view of the above disadvantages, the purpose of the present disclosure is to provide an axial flux permanent magnet motor fluid transport module that uses an axial flux permanent magnet motor and hides the motor in the impeller to reduce fluid transport. The volume of the module allows the fluid delivery module to be integrated into the tubing and can be closely matched to the tubing or applied to an open space to deliver a fluid.

In order to achieve the above object, the technical means of the present disclosure is to provide an axial flux permanent magnet motor fluid delivery module, comprising: a motor, which is an axial flux permanent magnet motor, the motor has a base a plurality of stators disposed on the base; a central shaft disposed at a center of the base, the central shaft protruding toward two sides of the base; and a plurality of rotors; an impeller, The utility model has a plurality of blades, the impeller is coupled to one end of the central shaft, and the impeller is inclined at an angle with respect to the central axis, the blade A side of the wheel facing the base is provided for the rotor.

In summary, the axial flux permanent magnet motor fluid delivery module of the present disclosure has the following advantages:

1. The rotor is installed at the impeller, so it can remove the slip caused by the existing shaft, so as to reduce the heat generation to improve the efficiency.

2. The motor disclosed herein is a tapered axial flux permanent magnet motor having characteristics of high torque and low flow resistance.

3. The axial flux permanent magnet motor fluid delivery module of the present disclosure has the characteristics of high rotation speed, high acceleration and small volume.

The embodiments of the present disclosure are described below by way of specific embodiments, and those skilled in the art can readily understand the other advantages and functions of the disclosure.

Referring to FIG. 1 and FIG. 2 , the disclosure is a first embodiment of an axial flux permanent magnet motor fluid delivery module, which can be a pump module. a group or a fan module, the axial flux permanent magnet motor fluid delivery module can be used in a pipeline or an open space to deliver a fluid, the fluid can be a liquid or a gas, the axial flux The permanent magnet motor fluid delivery module includes a motor 1 and an impeller 2.

The rotor 13 is disposed on one side of the impeller 2 facing the base 10, and the rotors 13 are arranged equidistantly. The rotor 13 is formed by a permanent magnet around which a coil is provided, since the structure of the rotor 13 and the stator 11 is existing. The technology is not the focus of this application, so it will not be repeated. The motor 1 of the present disclosure is an AXIAL FLUX PERMANENT MAGNET (AFPM).

The circuit unit 14 is disposed on the other side of the base 10 facing away from the impeller 2, and the circuit unit 14 is electrically connected to the stator 11.

The blade 20 is disposed on a side of the hub 21 away from the base 10, and the hub 21 is inclined at an angle θ with respect to the central axis 12, and the inclination angle θ can be 75 to 150 degrees. As described above, the rotor 13 is provided on one side of the hub 21 facing the base 10, and the rotor 13 and the stator 11 are parallel to each other.

In addition, since the tilt angle θ is such that the motor 1 has a tapered structure, the axial magnetic flux permanent magnet motor having a tapered structure has an average electromagnetic force distance greater than that of a general axial flux permanent magnet motor, that is, generally not tilted. Axial flux permanent magnet motor. The average electromagnetic force of an axially magnetic flux permanent magnet motor that is generally not tilted can be seen in detail. Jacek F. Gieras wrote AXIAL FLUX PERMANENT MAGNET BRUSHLESS MACHINES, so I don't want to discuss it more.

Referring to FIG. 3, the disclosure is disposed inside a pipeline 30. As shown, the circuit unit 14 provides a power supply to the stator 11 to make the stator 11 magnetic, between the stator 11 and the rotor 13. The magnetic action causes the impeller 2 to rotate, and the blade 20 drives the air flow to bypass the motor 1 thereby achieving the effect of airflow extraction or discharge.
