Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] The theoretical basis of the present invention is that when the magnet can only move around the center of the circle, if it encounters an arc-shaped magnet, the position of the magnet closest to the center of the circle will generate the greatest suction force on the magnet. If do a test, set up an environment as shown in Figure 1, magnet 102 can rotate around circle center 103, be provided with an involute arc type magnetizer 101 outside the magnet, magnet 102 can move to this magnetizer closest to under the action of magnetic force The part of the center of the circle is the position shown in Figure 2.

[0020] According to the above principles, the present invention proposes an energy-saving motor, including:

[0021] An inner rotor made of non-magnetic material, two or more permanent magnets are equidistantly arranged on the circumference of the inner rotor...

Abstract

The present invention provides an energy-saving electric motor to solve the problems of serious waste of magnetic force in the prior electric motor. An inner rotor made of the material having no magnetoconductivity, a permanent-magnet equally spaced on the circle, and a magnetizer positioned in the center of two adjacent permanent-magnets are provided in the present invention; two or more rotors made of the material having magnetoconductivity are distributed on a same circle of the external of the inner rotor, and said rotors that near the axes of the inner rotor is arc shaped, and the distances from the two endpoints to the axes of the inner rotor are different, wherein, the end that closer to the axes is provided with an electromagnet, and the electromagnets of any two stators are not adjacent. The energy-saving electric motor provided in the present invention has took full use of the function of magnetic force comparing the prior art, and the magnetic force needed in the rotating of the rotators is reduced on the premise of not adding equipment. As a result, the energy sources are saved and the efficiency of the electric motor is improved.

Description

technical field [0001] The invention relates to an energy-saving motor. Background technique [0002] Existing motors all include a stator and a rotor, and the rotor can rotate relative to the stator. The stator of the existing motor is an electromagnet, and the rotor is a magnetically conductive material, which generates magnetic force through the conduction of the stator to make the rotor rotate. The existing motor structure is equipped with permanent magnets on the rotor to provide the working point of the soft magnetic material, while the stator excitation only needs to provide a changing magnetic field without providing energy consumption at the working point of the magnetic material, so the motor has high efficiency, low current, and low heat generation. Low. Due to the existence of permanent magnets, the motor has a strong back electromotive force, and its own damping effect is relatively good, making it relatively stable during operation, with low noise and low-fre...
