Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, when the existing high-voltage permanent magnet variable frequency motor integrated machine is used in the mine environment, on the one hand, the air-cooling mechanism tends to cause excessive dust accumulation inside the motor, and at the same time, the water-cooling mechanism needs external water pumps and other equipment. The use of more troublesome problems in mines, a 3300V high-voltage permanent magnet variable frequency motor integrated machine proposed by the present invention

Abstract

The invention belongs to the technical field of variable frequency motors, and particularly relates to a 3300V high-voltage permanent magnet variable frequency motor all-in-one machine which comprisesa machine shell, a frequency converter assembly and a permanent magnet synchronous motor assembly. The permanent magnet synchronous motor assembly comprises a stator, a rotor and a rotating shaft. Amotor cavity and a frequency conversion cavity are formed in the machine shell. The permanent magnet synchronous motor assembly and the motor cavity jointly form a permanent magnet synchronous motor.The frequency converter assembly is installed in the frequency conversion cavity. A heat dissipation cavity is formed in the end, located in the motor cavity, of the machine shell. A rotating shaft inthe permanent magnet synchronous motor assembly extends into the heat dissipation cavity. By arranging a water storage cavity and a circulating cavity and utilizing rotation of the rotating shaft, water flow in the lower water storage cavity is pumped into the circulating cavity through the water pumping pipe, after the water flow makes contact with the pumped outside air, the water flow flows into the heat exchange cavity, the air flow enters the motor cavity, and heat conduction between the permanent magnet synchronous motor assembly and the machine shell is effectively accelerated and enhanced.

Description

technical field [0001] The invention belongs to the technical field of variable frequency motors, in particular to a 3300V high-voltage permanent magnet variable frequency motor integrated machine. Background technique [0002] In the prior art, the high-voltage permanent magnet frequency conversion motor integrated machine combines the frequency converter and the permanent magnet synchronous motor to form an integration. Under the premise of greatly reducing the volume, the motor and the frequency converter can work together, reducing the need for using cables to combine frequency conversion. When using inverters and permanent magnet motors, the electromagnetic interference and power loss caused by cables are especially convenient when used in mines. However, due to the integration of permanent magnet motors and frequency converters, both work Heat will be generated, and the integrated setting puts forward greater requirements for heat dissipation. At the same time, there a...
