[0002] With the development of mankind and the progress of science and technology, new mechanical products are constantly changing people's lives. The birth of motor-driven delivery pumps has made our production and daily life simpler and more convenient. The electric pump currently used is composed of two units: a vane pump and a motor. The power of the motor is transmitted from the motor rotor to the motor shaft, and then to the pump shaft by the coupling, driving the impeller of the vane pump to rotate; or the power of the motor is transmitted from the motor rotor to the motor shaft, driving the impeller of the vane pump installed on the motor shaft to rotate.

[0003] However, in the process of use, the traditional brushless motor adopts rigid connection. When the shaft is directly connected to the pump head or other loads, the concentricity is poor and the machining tolerance will cause resonance, which is easy to cause noise and abnormal sound. In addition, the traditional brushless motor uses ordinary ball bearings, the rotor is noisy, vibrates, and the motor life is short. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a low-noise and long-life brushless vane pump dedicated motor, including a stator and a rotor, the stator is provided with a rotor inside, and the first low-noise bearing and the second low-noise bearing are respectively installed on both sides of the stator;

[0006] A front end cover is installed on one side of the stator, and a boss opening of the front end cover protrudes out. A plastic adapter capable of reducing noise is installed on one side of the front end cover.

[0008] Preferably, a lead wire is installed at one end of the stator.

[0009] Preferably, a bracket is installed at the bottom of the stator.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model provides a plastic adapter, which can utilize a noise-reducing adapter to prevent the problems of loud noise and vibration generated when using a rigid connection.

[0012] 2. The utility model adopts low-noise bearings at both ends of the rotor through the combination of the first low-noise bearing and the second low-noise bearing, thereby reducing noise and vibration and improving efficiency.
