Problems solved by technology

However, when the direct drive motor is used in a low-speed system (such as a 10-20 rpm wind turbine generator), a large number of magnetic pole pairs are required, resulting in a complex system structure, a sharp increase in volume and weight; and the system must be used together The power converter converts the low-frequency voltage into a power-frequency voltage, which further leads to a complex structure and an increase in cost

Abstract

The invention provides an integrated motor comprising a permanent-magnetic gear and a general-purpose motor with rotors and stators, wherein the permanent-magnetic gear and the general-purpose motor are arranged in a case; the permanent-magnetic gear is connected with an external loading or a driving source by a low-speed rotating shaft, on one side and the permanent-magnetic gear is connected with the rotors of the general-purpose motor by a high-speed rotating shaft on the other side; or , the permanent-magnetic gear is connected with the rotors of the general-purpose motor by the low-speed rotating shaft on one side, and the permanent-magnetic gear is connected with the external loading or the driving source by the high-speed rotating shaft on the other side. As the permanent-magnetic gear and the general-purpose motor share a supporting system, a rotating shaft system, a bearing system, a radiation system, and the like, the whole integrated motor has simple and compact structure. In addition, the permanent-magnetic gear and the general-purpose motor of the integrated motor can be a radial or axial magnetic-flux permanent-magnetic gear and a radial or axial flux general-purpose motor according to the actual need.

Description

technical field [0001] The invention relates to an integrated electrical machine (Electrical Machine), in particular to an integrated electrical machine integrating an axial or radial magnetic flux permanent magnet gear and an axial or radial magnetic flux universal motor. Background technique [0002] Existing motors are generally designed to run at high speeds to reduce volume and weight and cost. When a motor used as an electrical generator (Electrical Generator) or a motor (Motor) needs to convert low-speed rotation into high-speed rotation or high-speed rotation into low-speed rotation, it usually needs to use a mechanical gearbox to complete the conversion. [0003] U.S. Patent No. 4,763,031 discloses an integrated universal motor and mechanical gearbox unit, wherein the gearbox includes a casing and a crankshaft bearing and an epicyclic gear train disposed within the casing, the bearings also serve as The shaft of the universal motor outside the housing.
