Embodiment Construction

[0032] The multi-port energy conversion device includes a high-speed side rotor, a low-speed side rotor and a magnetic modulation mechanism. The high-speed and low-speed side rotors are separated on both sides of the magnetic modulation mechanism, and there is an air gap between them and the magnetic modulation mechanism. The space is symmetrical about the magnetic modulation mechanism. The axis coincides with the axis of the magnetic adjustment mechanism. Permanent magnets are respectively installed on the low-speed side rotor and the high-speed side rotor, and the high-speed side and low-speed side rotors are respectively connected with the high-speed and low-speed rotating shafts, and the two rotating shafts can rotate freely. The magnet adjustment block is made of magnetic material, and the armature winding is placed on the magnet adjustment block (such as figure 2 shown).

Abstract

A multi-port energy conversion device comprises a low-speed-side rotor composed of a low-speed-side rotor yoke (1) and a low-speed-side permanent magnet (2) on the inner side of the low-speed-side rotor yoke (1), a high-speed-side rotor composed of a high-speed-side rotor yoke (6) and a high-speed-side permanent magnet (5) on the inner side of the high-speed-side rotor yoke (6) and a magnetism regulating mechanism composed of an armature winding (4) and magnetism regulating iron blocks (3) located on the two sides of the armature winding (4). The low-speed-side rotor and the high-speed-side rotor are located on the two sides of the magnetism regulating mechanism respectively, air gaps are reserved between the low-speed-side rotor and the magnetism regulating mechanism and between the high-speed-side rotor and the magnetism regulating mechanism, and the low-speed-side rotor, the high-speed-side rotor and the magnetism regulating mechanism are coaxial. The low-speed-side rotor and the high-speed-side rotor are connected with a low-speed rotating shaft and a high-speed rotating shaft respectively, and the rotating shafts can freely rotate. The conversion device is provided with two mechanical ports and an electric port, and multi-directional multi-output conversion of mechanical energy and electric energy is achieved.

Description

technical field [0001] The invention relates to a multi-port energy conversion device, which is suitable for occasions such as non-contact variable speed drive and multi-directional energy conversion, and belongs to the field of special electromagnetic equipment. Background technique [0002] As a speed conversion device, mechanical gears are widely used in industrial and agricultural production, national defense, aviation, aerospace and other fields. However, mechanical gears have problems such as high noise, high maintenance, short life, and non-isolation. The permanent magnet gear is a non-contact transmission device, which has the advantages of good reliability, stable transmission, long life, no friction energy consumption, no lubrication, no oil pollution, isolation of input and output, automatic overload protection, etc. Therefore, permanent magnet gears can replace traditional mechanical gears in many fields to reduce maintenance workload, reduce noise, pollution, a...
