Description

Technical Field

[0001] The utility model relates to the field of motors, in particular to an energy-saving motor. Background Art

[0002] The rotor slots of existing motors generally have four. If the motor needs to increase its speed, the output power must be increased.

[0003] In order to achieve the rotation speed of motors of the same level, that is, to increase the rotation speed of the motor under the same output power, an energy-saving motor is proposed. Summary of the invention

[0004] The purpose of the utility model is to provide an energy-saving motor for the purpose set forth in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an energy-saving motor, wherein a pump body is installed at one end of the motor housing, and also includes a rotor connected to the motor rotor inside the motor housing, and eight grooves are opened on the outer periphery of the rotor, and the inner wall of each groove is connected to a graphite vane.

[0006] As a further solution of the utility model: one end of the pump body is connected to a front cover by a No. 2 bolt, a No. 1 through hole is provided in the front cover and the interior of the pump body, and a No. 2 screw hole is provided in the motor housing at a position aligned with the No. 1 through hole.

[0007] As a further solution of the utility model: the other end of the pump body is connected to the motor housing by a No. 1 bolt, a No. 2 through hole is opened inside the pump body, and a No. 1 screw hole is opened at the position where the motor housing is aligned with the No. 2 through hole.

[0008] As a further solution of the present invention: the eight slots are equidistantly distributed around the outer circumference of the rotor in an inclined state.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. By setting eight slots, the volumetric efficiency of the pump body cavity can be increased, and the internal leakage from the exhaust side to the intake air can also be reduced. The eight slots divide the pump body cavity into multiple cavities, thereby increasing the compression ratio, improving the exhaust efficiency, and improving the vacuum degree. In general, the internal volumetric efficiency can be improved by adding more slots, and the compression ratio can be increased to improve the exhaust efficiency. Therefore, the motor structure can achieve the high-speed rotation effect of the same motor at a low speed. When the speed is reduced, the exhaust efficiency and the internal volumetric efficiency are high, and the power will inevitably be reduced. While ensuring the performance remains unchanged, the motor power can be reduced by adding more rotor slots, from a two-stage motor to a four-stage motor. BRIEF DESCRIPTION OF THE DRAWINGS

Eight grooves 4 are opened on the outer periphery of the rotor 3, and the inner wall of each groove 4 is connected to a graphite vane 9.

[0016] In this embodiment: the groove body 4 can increase the volumetric efficiency of the inner cavity of the pump body 2, and also reduce the internal leakage of the exhaust side back to the intake air. The eight groove bodies 4 divide the inner cavity of the pump body 2 into multiple cavities, thereby increasing the compression ratio, improving the exhaust efficiency, and improving the vacuum degree;

[0017] In general, the internal volumetric efficiency can be improved by adding more slots 4 and the exhaust efficiency can be improved by increasing the compression ratio. Therefore, the motor structure can achieve the high-speed rotation effect of the same motor under low speed. When the speed is reduced, the exhaust efficiency and internal volumetric efficiency are increased, and the power will inevitably be reduced, which has an energy-saving effect.

[0020] Please refer to Figure 1 and Figure 2The other end of the pump body 2 is connected to the motor housing 1 through a No. 2 bolt 5. A No. 2 through hole is opened inside the pump body 2, and a No. 2 screw hole 7 is opened at the position where the motor housing 1 is aligned with the No. 2 through hole.

[0021] In this embodiment: before fixing the front end cover, it is necessary to first install and fix the pump body 2, pass the No. 2 bolt 5 through the No. 2 through hole, and dock with the No. 2 screw hole 7, and tighten the No. 2 bolt 5. After tightening, the pump body 2 can be fixed, and then the front end cover can be installed.

[0022] Please refer to Figure 1 and Figure 2 The eight slots 4 are equidistantly distributed around the outer circumference of the rotor 3 in an inclined state.

[0023] In this embodiment: the groove body 4 can increase the volumetric efficiency of the inner cavity of the pump body 2, and also reduce the internal leakage from the exhaust side to the intake air. The eight groove bodies 4 divide the inner cavity of the pump body 2 into multiple cavities, thereby increasing the compression ratio, improving the exhaust efficiency, and improving the vacuum degree.
