Permanent magnet synchronous motor with high power density

Abstract

The invention provides a permanent magnet synchronous motor with high power density, and relates to the technical field of permanent magnet synchronous motors. A rotor device and a stator device are mounted in the mounting assembly, the rotor device is located in the stator device, and a heat dissipation device is mounted on the right side of the rotor device; the connecting assembly is installed on the left side of the rotor device, a soft start assembly is installed in the connecting assembly, and two sets of fixing devices are installed on the left side of the connecting assembly; the number of the anti-loosening assemblies is two, the two anti-loosening assemblies are installed on the installation assembly, and limiting assemblies are installed on the two anti-loosening assemblies; load damage is avoided, meanwhile, the reliability is high after starting, looseness cannot occur after long-time use, and the use stability is improved; the problem that looseness is prone to occurring after long-time use is solved.

Description

technical field [0001] The invention relates to the technical field of permanent magnet synchronous motors, in particular to a permanent magnet synchronous motor with high power density. Background technique [0002] The permanent magnet synchronous motor provides excitation with permanent magnets, which makes the structure of the motor relatively simple, reduces the cost of processing and assembly, and saves the collector ring and brush that are prone to problems, which improves the reliability of the motor operation; and because it does not need excitation current, without field losses, increasing the efficiency and power density of the motor. [0003] However, as far as the current permanent magnet synchronous motor is concerned, it is not convenient for the staff to adjust the gap between the rotor and the rotor, and the phenomenon of bore sweeping is easy to occur during use, and at the same time it increases the difficulty of assembly, and it is easy to be damaged unde...

Problems solved by technology

[0003] However, as far as the current permanent magnet synchronous motor is concerned, it is not convenient for the staff to adjust the gap between the rotor and the rotor, and the phenomenon of bore sweeping is easy to occur during use, and at the same time it increases the difficulty of assembly, and it is easy to be damaged under the action of the load when starting , which reduces the service life, and is prone to loosening when used for a long time, which reduces the reliability. The existing permanent magnet synchronous motor cannot meet the needs of contemporary use
