Abstract

The invention discloses an asymmetric double three phase camber line permanent-magnet synchronous electrical machine. The electrical machine comprises two parts that are stator combinations (I) and arotor (IV), wherein the three stator combinations (I) form a camber line structure on a circumference outside the rotor (IV), each stator combination (I) comprises a 12-slot stator module (II) and a 9-slot stator module (III) arranged side by side on the circumference outside the rotor (IV), the 12-slot stator module (II) and the rotor (IV) form a 12-slot 10-pole unit motor, the 9-slot stator module (III) and the rotor (IV) form a 9-slot 8-pole unit motor, the stator combinations (I) and the rotor (IV) together form the two-phase three phase electrical machine, permanent magnets are arranged in the rotor in an embedded manner in such a way that a V shape structure is formed, strong assembled magnetic effects are exerted, main magnetic flux can be effectively improved, torque density of theelectrical machine can be improved, the permanent magnets form 120 pairs of electrodes, the electrical machine is enabled to be characterized by low speed and large torque, and the electrical machineis applied to low speed and large torque direct driving occasions and large aperture astronomical telescope driving occasions.

Description

Technical field [0001] The invention relates to an asymmetrical double three-phase arc permanent magnet synchronous motor, which is applied to low-speed and large-torque direct drive occasions and large-aperture astronomical telescope drive occasions. Background technique [0002] Large-aperture astronomical telescopes play a vital role in the process of human exploration of the universe. It integrates astronomy, optics, mechanics, computers, automatic control and precision machinery and other technologies, and it has extremely high requirements for driving accuracy. Usually the frame of a large-scale astronomical telescope weighs hundreds to thousands of tons and is large. The total load moment is greatly affected by the attitude of the telescope and the environment. In order to simplify the structure of the telescope and reduce the influence of the control system of the structural moment of inertia, the large-aperture astronomical telescope The pitch axis of all adopts an open ...
